Introduction2.1 Overview

2.1 Overview.

SICAM Feeder Condition Monitor (FCM) is an Intelligent Electronic Device (IED) used for detecting and indi-cating short-circuits or earth faults with and without directional information. SICAM FCM accurately monitors, measures, and displays electrical variables and performs the condition monitoring task in a medium-voltage distribution grid. SICAM FCM is typically used in the medium-voltage secondary substation that ranges from greater than 1 kV up to 36 kV.

SICAM FCM measures the TRMS (True r.m.s value) for alternating voltage, alternating current, and power fre-quency. SICAM FCM calculates the active power (P), reactive power (Q), apparent power (S), power factor (cos Φ), and phase angle.

SICAM FCM consists of the following hardware components:

• 3 current inputs

• 3 voltage inputs

• 1 digital input

• 1 communication interface (Modbus RTU)

Figure 2-1 SICAM FCM Block Diagram

Applications

SICAM FCM is used in the medium-voltage energy distribution grid:

• As a fault indicator in the medium-voltage secondary substations

• As a directional and non-directional short-circuit detection and ground-fault detection

• As a simple power quality meter in various applications

Flush Mounting

SICAM FCM can be flush mounted in the panel and operated inside an enclosed dry room.

To mount SICAM FCM in the panel, follow the procedure:

• Cut a hole in the Ring Main Unit (RMU) panel measuring 92.0 + 0.8 mm x 45.0 + 0.8 mm (W x H).

• Carry out all required internal wiring connections.

Battery Freshness Seal Mode

NOTE

Battery Freshness Mode (BFM) enhances the battery life of the device. BFM keeps the battery from discharging until the device is plugged in and used for the first time and preserves the battery life. When the device is shipped, BFM is enabled to avoid the discharge of the battery power during shipping and storage.

To operate the device with the battery power for the first time, you disable the BFM by supplying an auxiliary power to the device. Before storage, it is always recommended that you enable BFM of the device to avoid discharge of battery after use. During installation and commissioning, the BFM is automatically disabled once powered-on from an external power supply.

Device Functions4.1 Fault Detection

4.1 Fault Detection.

The device determines the fault based on the following criteria:

• Overcurrent detection for phase currents (I>>) and earth current (INE >)

• Earth current and neutral-point displacement voltage (IE > and VE) for resonant earthed/isolated grid

where, VNE is an internally calculated value.

The device allows individual settings of time delays for phase and earth currents. If any of the above criteria is met, the device identifies the nature of the fault and determines the direction using the sampled values of the relevant voltage and current.

For more information on fault-detection parameters, see Figure A-3 and refer to the Fault Parameters > Phase Fault Detection menu and to the Fault Parameters > Earth Fault Detection menu.

4.2 Determination of Fault Direction.

The fault direction for the phase faults are determined by calculating the phase angles between the fault current and the corresponding phase-to-phase voltages. If the fault occurred is more than one phase and if the phase angles of the corresponding voltages cannot be measured accurately, the previously stored voltage phase-angle data is used to compute the fault direction.

Device Functions4.3 Direction Determination of Phase Elements

4.3 Direction Determination of Phase Elements.

In SICAM FCM, the directional overcurrent element operates for any faults either in the forward direction or in the reverse direction. The forward direction refers to the power flow away from the busbar and the reverse di-rection refers to the power flow towards the busbar.

The directional determination of phase elements works in the quadrature connection to prevent the loss of po-larizing quantity for close-in phase faults. Each current element has a direction by a voltage derived from the other 2 phases. This connection introduces a 900 phase jump (current leading voltage) between reference volt-ages and operating quantities (currents). A fault is determined to be in the selected direction if its phase rela-tionship lies within a quadrant of ± 850 on either side of the characteristic angle, which is hard-coded as +450.

Figure 4-1 Direction Determination of Phase Elements

4.4 Directional Earth Fault (Compensated/Resonant Earthed).

In compensated/resonant earthed grid, the arc-suppression coil is configured to match the capacitive charging currents, such that when an earth fault occurs the negligible fault current flows through the coil. The character-istic angle is set to 00 and a boundary of +900 is used to detect the direction of the resistive component within the residual currents.

The measuring element circuit is subjected to cosine component of the zero-sequence current for directly mea-suring the real current due to losses. The characteristic angle is set to 00.

Calculate the active power (P) and if the value is falling in the 1st and the 4th quadrant, then the direction is forward. If the active power (P) is falling in the 2nd and 3rd quadrant, then the direction is shown as reverse.

For more information on directional earth fault parameters (compensated/resonant earthed), see Figure A-4 and refer to the Process Parameters > Earth Connection menu.

Device Functions4.5 Directional Earth Fault (Isolated Earthed)

Figure 4-2 Directional Earth Fault (Compensated/Resonant Earthed)

4.5 Directional Earth Fault (Isolated Earthed).

During earth-fault on isolated distribution grid, no fault path is detected and subsequently no fault-current flows. The phase-to-neutral capacitive charging current of the healthy phases for the entire grid is supplied through the fault path. This produces a current that is used to detect the presence of the earth fault. It appears as a residual current which lags the residual voltage by 900 and the characteristic angle is -900.

Calculate the reactive power (Q) and if the value is falling in the 1st and the 2nd quadrant, then the direction is forward. If the reactive power (Q) is falling in the 3rd and 4th quadrant, then the direction is shown as reverse.

For more information on directional earth-fault parameters (isolated earthed), see Figure A-4 and refer to the Process Parameters > Earth Connection menu.

Device Functions4.6 Inrush-Current Detection

4.6 Inrush-Current Detection.

SICAM FCM detects the presence of high levels of 2nd harmonic current which is indicative, for example, for a transformer inrush current. If the 2nd harmonic current is greater than 10 % of the fundamental, then the device does not issue an indication for any detected fault in the grid for a duration of less than 2 seconds.

The detection enable flag for earth and phase controls the protection algorithm. These flags are disabled if the settings value of phase and earth are set to zero respectively.

The inrush-current detection function starts when the current exceeds the set values (I>> for I1, I2, and I3 and IE> for IE).

If the fault current persists for the respective time setting (tI>> for phases, tIE for earth), the inrush-current block-ing function checks for the inrush current. The inrush current is detected by analyzing the magnitude of 2nd harmonic component of phase vectors. The inrush current is detected if any of the 2nd harmonic component of phase vector exceeds 10 % of the I>> setting.

If the inrush current is present the detection function blocks the inrush-current detection to generate an indica-tion. If the inrush current is present for more than 2 seconds, the function is disabled and the inrush-current detection function is allowed to generate an indication. The detection function blocks both the phase and earth fault detection.

Device Functions4.7 Voltage Alerts

4.7 Voltage Alerts.

The device displays overvoltage and undervoltage alarms as well as warnings when it is connected to a grid. The 2 threshold voltages of Vmax and Vmin provide alarms and warnings which are displayed and communicated via Modbus. The device maintains a hysteresis band of 2 % for indicating undervoltage and overvoltage alarms and warning. The alert screens on the HMI are displayed once the thresholds are exceeded and are cleared once the voltages are restored back to normal.

For more information on voltage alerts parameters, see Figure A-3 and Overvoltage Alarm and Fault Param-eters > Undervoltage Warning and Undervoltage Alarm menu.

4.8 Fault Indication.

When the device detects a fault, the following components are activated:

• LED - The red LED is turned on and indicates a fault

• LCD - Displays current and voltage values with the fault type and fault information sent via Modbus

• Modbus - Fault type and additional fault information will be sent to the RTU

NOTE

If any fault is detected, the red LED flashes for every 1 second. In case, SICAM FCM is not powered through auxiliary supply, the device reaches to sleep mode and the communication with RTU is disconnected. In the sleep mode, you can press any one of the key to view the events. After 8 hours of sleep mode, the device needs a power on from a power supply.

In the sleep mode, the fault reset and the effect of changes made in parameters can take few minutes.

NOTE

Under sub zero temperature -20 0 celsius, the LCD display can take up to 2 minutes to start or display the data.

4.9 Fault Reset Modes.

After the fault indication, you can reset the fault status of device through any one of the following modes:

• Auto reset as per user-defined time settings. see Figure A-3and refer to Fault Parameters > Auto Reset Time menu.

• Digital input

• HMI selection from menu

• RS485/Modbus interface

Device Functions4.10 Measurements and Derived Values

4.10 Measurements and Derived Values.

The device internally calculates and displays the derived values. The following table shows the measured values and derived values of the device when it is connected to the medium-voltage grid.

Table 4-1 Measurements and Derived Values

NOTE

The phase current measurements I1, I2, I3 may vary by 1 A for the measured range from 5 A to 40 A. The earth current measurement IE may vary by 0.3 A for the measured range from 1 A to 8 A.

4.11 RTC Synchronization.

SICAM FCM provides an internal real-time clock. In order to get an external time synchronization, use Modbus for the accurate time stamp of events. The real-time clock synchronization is mandatory for a valid time stamp.

The device needs a time synchronization, whenever it resumes from the sleep mode to ensure correct time and date. Also a time and date update is required when the device is powered on after 8 hours of sleep mode.

4.12 Archive Logging.

An archive log is composed of:

• Event logs

The device stores 20 faults as event logs on the non-volatile memory. The event logs consists of time stamp and fault current values. It is designed as a ring buffer where in a new fault will always over write the oldest stored event.

• Trailing Pointers

The minimum and maximum values of current and voltage are archived at every 15 minutes, 30 minutes, 45 minutes, 1 hour, 24 hours, 1 month, and 1 year.

For more information on parameters of archive logging, see Figure A-3 and refer to Events and Trailing Point-ers menu.

NOTE

Whenever the device is powered on or it resumes from the sleep mode, the date and time display format would be 01-01-2012, 00:00:00. The Modbus registers for date and time is set as invalid.

Introduction

Modbus is a fieldbus which is used to exchange data between programmable logic controllers (PLCs) and other devices via the communication protocols. The communication protocol is typically based upon the master/slave system over a serial line (RS485).

Modbus is a master/slave communication. The Modbus master requests data from the slaves which are con-nected to the bus. The slaves answer to the request from the master. The device works as Modbus Slave and supports communication via RS485. Regardless of the transmission mode, the communication cycle and con-tents remain the same. The message frame contains the following format:

• Device address

• Function code

• 8-bit data bytes

• Error Checking

The Modbus data models are classified as follow:

• Bit type data

- Discrete Input

- Coil

• Register type data

- Input Register

- Holding Register
