 Facilitates
standardization for small/medium intertie and generator protection applications
The M-3410A Intertie/Generator Protection Relay is a microprocessor-based
unit that uses digital signal processing technology to provide up to twelve
protective relaying functions for intertie protection or up to eleven
protective relaying functions for generator protection.
Generator Protection
The relay can protect a generator from abnormal voltage, abnormal frequency,
motoring (loss of prime mover), phase faults, ground faults, and unbalanced
currents. In addition, sync check may be applied for proper connection
of the generator to the bus.
Intertie Protection
The relay can protect the utility from having generators island on the
distribution system after the utility disconnects power from the feeder.
This is accomplished by monitoring the intertie (point of common coupling
to the utility) for abnormal voltage, abnormal frequency, ferroresonance
and excessive power import/export, which can indicate loss of utility
supply. The relay also provides detection of phase and ground faults,
as well as current and voltage unbalance on the utility system. In addition,
sync check may be applied to supervise closure of the intertie breaker
according to the interconnected utility’s practice.
