FEEDER CONTROL METERING PROTECTION RELAY

Comprehensive Feeder Protection

FCOMP

The combines the ruggedness of conventional feeder

protection and the versatility of advanced feeder protection

features, annunciations and metering in MV and LV switchgear

assemblies into one single, simple-to-configure, communicating

module with a large color display.

It is scalable, modular and of the right size to cater to your varied

feeder protection requirements.

To make it suitable for the often dusty and corrosive environs of

substations (as in process industries and petrochemical

complexes), the FCOMP has a conformal coating on its

hardware.

User-friendly options and features

Universal auxiliary power supply of 80-264 VAC /

110-250 VDC oOperating temperature range of -20 C to 85 C

Current-based metering and protection with optional

scalability for voltage-based metering and protection built

into a single unit

Reduced and simplified wiring(especially in auto bus transfer

schemes) and reduced dependence on auxiliary components

in different schematics through varied DI/DO combinations

Facilitation of reconfiguration of auto bus transfer conditions

/interlocks, configuration of load shedding and load-sharing,

reverse interlocking, conditions for tripping and closing of the

circuit breaker, annunciation and status exchange.

Six configurable pushbuttons for control and

12 configurable LEDs for indication

INTERFACE SOFTWARE

TMThe COMPfigurator is a specialized software designed to interface with the FCOMP.FCOMP parameters can be configured, metered, monitored

TMthrough the COMPfigurator .

The FCOMP settings file can be generated by the TMCOMPfigurator by either of these methods:

Online mode (FCOMP-powered on and connected with TMthe COMPfigurator )

Offline mode (FCOMP disconnected). The settings file is generated with FCOMP disconnected and downloaded later onto it.

The settings file comprises the following configurations which can be modified as per user requirement:

General settings (CT ratio, PT ratio, sync input, DIO, AIO, phase rotation, nominal freq, etc.)Protection settings (All current and voltage-based protections)Pushbuttons LEDsDigital output, analog outputEvent recordPre- and post-fault settings of disturbance recordSingle line diagram

TMThe COMPfigurator can also be used for real time / online metering of:

Analog Data: Current, Voltage, Frequency, Power, Power factor Digital Data: Digital input status, digital output status, electrical fault status

TMThe COMPfigurator can also be used to monitor and record parameters like event history, sequence of events (1024), disturbance record (64 samples / cycle x 6 channels) and hour meter.

TMThe COMPfigurator has an option to save the setpoint files file and event records, as required, with password protection.

TMCOMPlogic

TM TMThe COMPlogic is part of the COMPfigurator software.It is used to programme the FCOMP to tailor the control and operation of the circuit breaker.

The COMPlogic includes:Arithmetic operation (+, -, >, <, =)Logic Gate (AND, OR, NOT)Timer (Pick up, Drop out) Latch512 lines for control equations

Note: For details of sample control equations to implement schematics, refer to the FCOMP operation manual.
