APPLICATION

GRD150 feeder manager is designed for protection, control, metering and supervision of medium voltage networks.

GRD150 includes multiple, high accuracy, overcurrent protection elements (for phase and/or earth fault) with

inverse time (IDMTL) and definite time delay (DTL) functions. All phase, earth and sensitive earth fault overcurrent elements can be independently subject to directional control. The directional elements provide user-settable characteristic angles.

Other protection functions are also available, including thermal protection to IEC60255-8, negative sequence overcurrent protection, under/overvoltage and under/ over frequency protections.

GRD150 provides continuous monitoring of internal circuits and of software. External circuits are also monitored, by trip circuit supervision, CT and VT supervision, and CB condition monitoring features.

A user-friendly HMI is provided through a backlit LCD, programmable LEDs, keypad and menu-based operating system. PC access is also provided, either for local connection via a front-mounted RS232 port, or for remote connection via a rear-mounted RS485 or fibre optic port. The communication system allows the user to read and modify the relay settings, and to access data gathered by the relay’s metering and recording functions.

Data available either via the relay HMI or communications ports includes the following functions.

 Metering  Fault recording  Event recording  Alarm recording  Disturbance recording (available via

communications ports)
