Insulation resistance measurements and tests low-and-high

voltage installations

Ensure the safety of your installation

Every new electrical installation has a high insulation resistance to guarantee safety of the

installation and to minimize leaking current. As your electrical installation ages, moist,

dirt, and damages can decrease the insulation resistance. When the insulation resistance

drops below the acceptable level, it can lead to electrical shocks. This can result in

serious injuries, downtime, high costs, and fi re damage. Therefore, legislation requires you

to monitor the condition of your installation’s insulation.


Bakker Sliedrecht can determine the condition of the insulation resistance with

specialized measurement equipment. The insulation resistance is determined by

matters can be solved directly during the inspection.

Your insurance demands a NEN-EN 50110-1 inspection

Not only legislation requires you to comply with NEN-EN 50110-1. Your insurance

can also require you to comply. It is important to meet the requirements of your

insurance requiring the NEN-EN 50110-1. Without prove that you are compliant with

NEN-EN 50110-1 they may not cover damage. Bakker Sliedrecht can help you meet

the requirements of your insurance. Moreover, we are happy to support you with all

uncertainties you may have regarding your insurance policy or provide a second opinion.

Protective relays inspection


Protective relays are attached to electrical installations to detect abnormalities in the

current, voltage, and frequency, fl owing in the electrical system. When an abnormality

is detected, it will send a signal to a trip coil on a particular device, such as a circuit

breaker, that is designed to interrupt the circuit, thus limiting damage to equipment and

personnel.

If the protective relays are not monitoring or measuring properly, they can cause non-

tripping or false tripping. This can result in dangerous situations and damage to critical

component, or unnecessary downtime of critical equipment.

INSPECTIONS

Highlights:

Ensure the safety of your staff and installations

Prevent unnecessary downtime

For low-and-high voltage installations

Inspection of all brands and types

Periodic comprehensive inspection

Since these devices operate during abnormal conditions on the power system, the only

way to ensure correct operation is by a periodic comprehensive inspection, maintenance,

tests and calibration programs.

Safeguard the protection functionality

Bakker Sliedrecht offers brand independent protective relays inspections and test

programs that inspect all protection systems of low-and-high voltage installations that

ensure an automatic stop in case of emergency. Amongst others, the following parameters

and functionalities are checked by current and voltage injection with our calibrated

portable protective relays testing kit.

Online partial discharge measurement on high voltage cables

Prevent high unexpected costs and damage to your high voltage cables and

installation

Failure of the high voltage (HV) cable network in your installation can lead to unexpected

downtime and extra costs for your organization. These costs include urgent corrective

maintenance costs, production losses and stress to fi nd the origin within the total

(underground) cable network. One of the causes of cable failure is Partial Discharge.

Partial Discharge is a dielectric breakdown caused by small deterioration (cracks) which

is to small to cross between the conductors. This will lead to eroded insulation (usually

forming a tree-shaped pattern of detoriation). In the end this can lead to a complete

breakdown of your HV cables and installation, damage to your installation or even fi re and

explosions.

INSPECTIONS

Highlights:

Improved reliability and safety of your installation by minimizing costly unexpected

breakdowns

Measurements during operations (online) without disrupting your operation

Discover detoriation trends in the insulation

Benchmark with similar cables worldwide

Minimize unnecessary cost by proposing only replacements of segments of your cable

Calibrated measurement equipment

Report including recommendations on replacement of cable sections

Maximize uptime with online measurement and direct replacements

To optimize the reliability and performance of your electrical system while keeping

your maintenance cost and time effi cient it is essential to determine the possible fault

locations in an early phase. Bakker Sliedrecht can assist you with preventive maintenance

and inspections. Partial Discharge measurement is an inspection that reveals the weak

points in the isolation of your high voltage cable. Our technicians comply with IEC

60270:2000/BS EN 60270:2001 standards. Bakker Sliedrecht will measure the partial

discharge of cables during operation (online) to determine their condition without any

downtime.

The collected data is benchmarked within a worldwide database and analyzed by Bakker

Sliedrecht to discover trends and provide a lifetime expectation. The report categorizes

HV cables in fi ve categories ranging from healthy to immediate replacement needed.

Bakker Sliedrecht can also take care of all follow-up actions, such as the replacement of

cable sections and advise on further maintenance planning. With replacing only the cable

sections that are necessary, lower costs are made.

Power Quality Analysis on Low Voltage electrical systems

The impact of poor power quality

Are you experiencing harmonic distortion problems after changes, like a retrofi t, to

your installation? Poor power quality results in extra costs due to excessive energy

use, unscheduled stops, increased maintenance, and replacement of components that

have aged too quickly. End use equipment, such as automation systems or computers,

have become more sensitive to disturbances in the power quality that arise both on the

supplying power system and within the electrical system. Furthermore, equipment is more

interconnected in networks and industrial processes so that the impacts of a problem with

any piece of equipment are much more severe.

Analyze your power quality to discover disturbances

Bakker Sliedrecht can analyze the power quality of your electrical installation by

INSPECTIONS

Highlights:

Calibrated measurements


Minimize energy losses

Prevent lifetime reduction of electrical equipment

Measurements during operation

Fast measurements of high speed transients

Report including recommendations for corrective measures

Bakker Sliedrecht can take care of complete power quality mitigation

Power quality analysis can be part of a predictive maintenance program

performing measurements during operation to identify disturbances. These disturbances

can take many forms ranging from: harmonics, voltage sags/swells/ unbalances, fl icker,

and transients etc. Our specialized measurement equipment enables us to accurately

monitor and record voltage, current, power, harmonics and many other relevant

parameters. Short term testing can be used to record the behavior of specifi c equipment.

Long term testing can be used to record ongoing power quality parameters and detect

intermittent electrical supply issues.

Cost-effective power quality power mitigation

Analyzing power quality is an effective way to identify electrical disturbances without

having to shut down the system. Once disturbances have been identifi ed, Bakker

Sliedrecht can advise and implement cost-effi cient solutions for power quality mitigation.

We can make sure that the power quality level is compliant with standards that are

required by classifi cation. The investments for solving power quality issues often have a

quick return on investment.
