0A consistent design of offers from Medium Voltage to Low Voltage

All Merlin Gerin offers are designed according to electrical, mechanical and communication consistency rules.The products express this consistency by their overall design and shared ergonomics.

Electrical consistency:

Each product complies with or enhances system performance at co-ordination level: breaking capacity, Isc, temperature rise, etc. for more safety, continuity of supply (discrimination) or economic optimisation (cascading).The leading edge technologies employed in Merlin Gerins Guiding System ensure high performance levels in discrimination and cascading of protection devices, electrodynamic withstand of switches and current distributors, heat loss of devices, distribution blocks and enclosures.Likewise, inter-product ElectroMagnetic Compatibilty (EMC) is guaranteed.Discrimination guarantees co-ordination between the operating characteristics of serial-connected circuit-breakers. Should a

fault occurs downstream, only the circuit-breaker placed immediately upstream from the fault will trip.

Mechanical consistency:

Each product adopts dimensional standards simplifying and optimising its use within the system.It shares the same accessories and auxiliaries and complies with global ergonomic choices (utilisation mode, operating mode, setting and configuration devices, tools, etc.) making its installation and operation within the system a simpler process.

Direct connection of the Canalis KT busbar trunking on the Masterpact 3200 A circuit breaker.

Communication consistency:

Each product complies with global choices in terms of communication protocols (Modbus, Ethernet, etc.) for simplified integration in the management, supervision and monitoring systems.

Thanks to the use of standard Web technologies, you can offer your customers intelligent Merlin Gerin switchboards allowing easy access to information: follow-up of currents, voltages, powers, consumption history, etc.

Insulation monitoring is provided on ITsystems to detect and indicate insulationfaults as soon as they occur.The basic function is carried out by anInsulation Monitoring Device (IMD), alsoreferred to in certain documentation as apermanent or continuous insulation monitor(PIM or CIM respectively). The monitoringdevice injects a DC or low-frequencyAC voltage between the installation andearth. The insulation resistance is determinedfrom the resulting current. This technique canbe used on all types of installations: AC, DC,rectified, mixed AC/DC, etc.

36off-line insulationmonitoringThe failure of a motor to start can haveserious consequences. This is especiallytrue in the following applications:c safety equipment (fire pumps, smokeextractors, etc.);c production (glass works, cement plants,etc.);c manufacturing processes (rolling mills, etc.).Motors often fail to start due to insulationproblems caused by the humidity thataccumulates in the microscopic cracks of theinsulation during periods when the motor isnot running. The SM21 device monitors theinsulation of critical motors while they areoff-line. Insulation faults give rise to analarm or motor starting lock-out.

fault locatingOnce detected, an insulation fault must belocated and eliminated in order to guaranteemaximum continuity of supply.Manual fault locatingThe fault is located by testing different pointsin the installation, one after another, using aVigilohm System XRM mobile receiver and acurrent probe. The receiver captures thelow-frequency fault locating signal.Two cases may be encountered:c the installation is equipped with an XM200or XM300C insulation monitoring device(Vigilohm System).In this case, the manual system is used tofine-tune the results of the automaticlocating systemc the installation (relatively small or anisolated sub-system) is equipped with aninsulation monitoring device for DC injection.In this case, a Vigilohm XGR portablegenerator is used together with an XRMreceiver.

communication featuresIn addition to displaying the insulation valuesit measures for the installation as a whole, aninsulation monitoring device can also providea centralised display for informationconcerning specific circuits. It receives thisinformation from communicating insulationfault locators and detectors distributedthroughout the installation. All this informationmay also be transmitted to a remotesupervisory system.These communication features satisfy theoperating requirements of modern electricalinstallations. All information concerning theinsulation can be transmitted via acommunication bus for display on acentralised insulation monitoring device or toa supervision system for centralisedprocessing and management.

prevention of insulationfaultsPrevention is the best way to ensure thecontinuity of supply of electrical installations.It may be applied in two ways:c the insulation monitoring device signals adrop in the insulation resistance below anon-critical prevention threshold determinedby the user;c the measurements are transmitted to asupervisor, which can then process them topredict insulation faults on ageing cables.These indications can be used to schedulepreventive maintenance.

New devices can be added atany time to adapt to installationmodifications or provide higher levels ofmonitoring.

insensitivity to electricaldisturbancesThe Vigilohm System offers bothmeasurement accuracy and insensitivity toelectrical disturbances. Designed to operateon modern installations, it is not affected bythe harmonics generated by loads such asvariable speed drives, UPSs and switch-mode power supplies.

easier operation ofIT systemsAn installation implementing the IT system,i.e. isolated from earth or connected to earththrough a sufficiently high impedance, givestop priority to continuity of supply.Today, the operation of such installationscan be greatly facilitated by the use ofdevices that offer functions going far beyondthe simple fault signalling imposed bystandards.

... with Vigilohm SystemVigilohm System is a range of Merlin Gerinproducts meeting the needs of IT systems interms of performance, practical operationand continuity of supply.This range features modular design. It ismade up of Insulation Monitoring Devices(IMDs) and fault detection and locatingdevices. Some of these devices makeindependent measurements of the insulationresistance on each circuit.In addition, the Vigilohm System cancommunicate with a supervisor or PLC.

principle and functionsThe basic device is the InsulationMonitoring Device (IMD). It injects a low-frequency AC voltage between earth and theinstallation. Based on a measurement of theresulting current, the Vigilohm Systemaccurately determines the true insulationresistance of the installation and its earthcoupling capacitance. This technique can beused on all types of installations: AC, DC,rectified, mixed, etc.Fault locating is the main functionassociated with insulation monitoring.Toroids placed on the various circuitscapture a signal proportional to the currentinjected by the insulation monitoring device.This signal is transmitted to fault detectionand locating devices which automaticallyidentify any faulty circuit.Distributed measurements of theinsulation resistance and the earth leakagecapacitance are possible on each circuit viathe toroids used for fault locating.Centralisation on a supervisor. Via acommunication bus using JBUS protocol,the Vigilohm System can forward allmeasurements, information and events to asupervisor. In this way, the supervisormaintains full knowledge on the insulationstatus of the overall installation and theindividually monitored circuits. Thesupervisor (or PLC) can be connected to aprinter to log all events occurring on theinstallation, complete with location andtimestamp.Adaptation to variable installationconfigurations. The system automaticallyexcludes all but one insulation monitoringdevice connected to the same set ofbusbars.

Vigilohm: presentationVigilohm System:two examples of installations

automatic fault locatingwith or without supervisionThe following examples cover two typicalinstallation configurations with insulationmonitoring and fault locating systems.Example 1:c automatic fault locating with localdisplay.The use of an XM200 insulation monitoringdevice together with XD301 and XD312detectors represents the typical caseproviding basic detection and automaticlocating of insulation faults on the mainfeeders as well as on certain secondaryfeeders.Fault locating can be fine-tuned using anXRM mobile receiver and a current probe todetermine the exact location of the fault onthe faulty circuit.The auto-exclusion of other XM200 insulationmonitoring devices is controlled by the circuitbreaker position indication contacts.

Example 2:c measurement and automatic faultlocating with local and centraliseddisplay, for an installation with more thanone set of busbars and a bus couplingcircuit breaker.The measurement of the insulationresistance on the main feeders is provided inaddition to fault detection with automaticlocating (XL308/316 and XML308/316).The secondary feeders are monitored simplyby an XD312/301 detector or by an XD308Cdetector that communicates detected faults tothe supervisor (via the XTU300 interface).The architecture of the installation (severalsources and sets of busbars) makes itnecessary to use an XTU300 interface tohandle the exclusion of other insulationmonitoring devices and the link between thelocators and their corresponding insulationmonitoring devices.

Vigilohm: functions and characteristicschoosing an insulation monitoring devicefor different types of installations

device XM200 XM300C

Continuity of supply is the requirement that most oftenleads designers to chose the IT system for an electricalinstallation.This requirement may apply to the entire installation(e.g. chemical process plant, steel plant, etc.).Such an installation requires continuous monitoring ofthe insulation level.

The requirement for continuity of supply may apply toonly a part of an installation, for example a single shopor plant, or a circuit subject to special conditions(safety lighting).In this case, it is recommended to use the IT systemfor this part of the installation, whatever the systemused for general distribution.

In many cases, the use of direct current corresponds toa need for continuity of supply. The use of an ITsystem and insulation monitoring is thereforeconsistent with this choice.

The use of motors in industrial processes creates a furtherneed for insulation monitoring. By checking the insulationwith power off, the presence of insulation faults can bedetermined before starting motors (fire pumps, smokeextractors, etc.). It is also possible to prevent motor startingautomatically if the insulation resistance is below a certainthreshold.

basic function: overallinsulation monitoringThe XM300C provides overall insulationmonitoring of electrical installations byinjecting a low-frequency AC voltagebetween the installation and earth.

main functionsc measurement:v insulation resistance,v earth leakage capacitance;c indications:v satisfactory insulation resistance (greenlight on bargraph),v drop in insulation resistance: below prevention threshold (orange lighton bargraph and relay actuated), below fault threshold (red light on bargraphand two relays actuated, including one witha failsafe feature),v transient faults (orange light);c display:v measurements,v events detected by any XL308/316locators connected.All this data is accessible locally on the LCDscreen of the insulating monitoring deviceand remotely via the Vigilohm System bus.

additional functions withother devicesLocating of faulty circuitsThis function is obtained by using theXM300C together with:c XL308 and XL316 locators connected to 8or 16 toroids. They are linked to theXM300C by the Vigilohm System bus;c XD308C communicating detectors. Theyare linked to the XM300C by the VigilohmSystem bus, and connected to the toroidsplaced on the circuits to be monitored;c XD301 and XD312 detectors connected tothe toroids placed on the circuits to bemonitored;c an XRM mobile receiver and a currentprobe to fine-tune the automatic locatingresults.All these devices can be combined on agiven installation.Distributed measurementsThis function is provided by combining anXM300C monitoring device (or anXML308/316 monitoring-locating device)with XL308 or XL316 locators.These locators measure the insulationresistance and the earth leakagecapacitance of each of the circuits.They have a fault alarm threshold that canbe set to a different levels for each channel.

Vigilohm: functions and characteristicscommunicating Vigilohm SystemXM300C insulation monitoring device

communicationCommunication with the supervision system.The XLI300 and XTU300 interfaces allowmonitoring devices + locators+ communicating detectors to exchangeinformation with a supervision system viaJBUS protocol.The XLI300 and XTU300 interfaces connectto the Vigilohm System bus and allowtimestamping of insulation monitoringevents.

configuration managementOn installations with a number of insulationmonitoring devices installed to covervariable configurations, only one device at atime can be allowed to inject a voltagebetween earth and the installationdownstream of the incoming circuit breaker.For this reason, the system must managethe exclusion of other connected insulationmonitoring devices. In addition, each locatormust identify the monitoring device fromwhich it is to capture the signal.The exclusion of monitoring devices andtheir identification by the locators is handledin one of the following manners:c by the XTU300 interface for multiplebusbar installations;c by the XLI300 interface for single busbarinstallations.In both cases, the circuit breaker positionindication contacts are wired to the all-or-nothing inputs of the XM300C orXML308/316.If only XD308C detectors are associatedwith the XM300C, monitoring deviceexclusion is handled by the XLI200 interface.

standardsThe XM300C insulation monitoring devicecomplies with the following standards:c IEC 364, parts 4 and 5;c class CPI/XA of UTE C 63-080.It is implemented in accordance withstandard NF C 15-100 paragraph 413.4;c IEC 61557-8.

installation and connectionc horizontal flush mounting on the front faceof a cubicle or enclosure;c easy mounting in Prisma enclosures usingthe corresponding mounting plates and frontplates that come with the appropriatecut-outs;c the devices are interconnected by shieldedcables (double 0.75 mm2 twisted pairs).The resistance between the two most distantpoints must not exceed 12 .The coupling capacitance between pairsmust not exceed 250 nF;c if no XTU300 or XLI300 interface isincluded, operation of the Vigilohm Systembus will require an XAS interface.

additional functions withother devicesIt is possible to monitor more than 8 or 16circuits by adding any of the followingdevices:c XL308 or XL316 locators that measure theinsulation resistance on each additionalcircuit;c XD308C communicating detectors thatautomatically detect the faulty circuit andcommunicate via an XLI300 or XTU300interface;c XD301 and XD312 detectors thatautomatically detect the faulty circuit andprovide local indications.The communicating detectors and locatorsare connected to the XML308/316 via theVigilohm System bus.

communicationCommunication with the supervision system.The XLI300 and XTU300 interfaces allowmonitoring devices + locators+ communicating detectors to exchangeinformation with a supervision system viaJBUS protocol.The XLI300 and XTU300 interfaces connectto the Vigilohm System bus and allowtimestamping of insulation monitoring events.

configuration managementOn installations with a number of insulationmonitoring devices installed to cover variableconfigurations, only one device at a time canbe allowed to inject a voltage between earthand the installation downstream of theincoming circuit breaker. For this reason, thesystem must manage the exclusion of otherconnected insulation monitoring devices. Inaddition, each locator must identify themonitoring device from which it is to capturethe signal.The exclusion of monitoring devices and theiridentification by the locators is handled in oneof the following manners:c by the XTU300 interface for multiple busbarinstallations with bus coupling;c by the XLI300 interface for single busbarinstallations.In both cases, the circuit breaker positionindication contacts are wired to the all-or-nothing inputs of the XM300C orXML308/316.

standardsThe XML308 and XML316 devices complywith the following standards:c IEC 364, parts 4 and 5;c class CPI/XA and DLD/M of UTE C 63-080.They are implemented in accordance withstandard NF C 15-100 paragraph 413.4;c IEC 61557-8.

toroidsThe XML308 and XML316 devices operatewith type A and OA toroids. They are alsocompatible with type XS toroids.

installation and connectionc horizontal flush mounting on the front faceof a cubicle or enclosurec easy mounting in Prisma enclosures usingthe corresponding mounting plates and frontplates that come with the appropriate cut-outs;c the devices are interconnected by shieldedcables (double 0.75 mm2 twisted pairs). Theresistance between the two most distantpoints must not exceed 12 .The coupling capacitance between pairs mustnot exceed 250 nF;c connection of toroids using twisted, shieldedcable (1 pair);c if no XTU300 or XLI300 interface isincluded, operation of the Vigilohm Systembus will require an XAS interface.

Vigilohm: functions and characteristicsVigilohm TR22A and TR22AH insulation monitoring devices

(1) For the TR22A, the upper limit is extended to this value by adding a P1 subassembly. This is not possible for the TR22AH.(2) Failsafe: the relay is disactivated either on occurrence of a fault or if the auxiliary supply voltage accidentally fails.(3) Locating signal changeover switch: this device identifies the faulty feeder during locating by opening each feeder in turn.When the faulty feeder is opened, the alarm sounds.(4) Suitable for use in all climates:c damp heat, equipment not operating (IEC 60068-2-30)c damp heat, equipment operating (IEC 60068-2-56)c salt mist (IEC 60068-2-52).
