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.
