The relay will prevent closure of the circuit breaker if the differences in phase angle, slip frequency or magnitude of the voltages falls outside prescribed limits.<\/p>\n<p>If the parameters are within limits, the relay will issue an output which can be used to close the circuit breaker directly or in conjunction with an auto-reclose scheme. Housed in a 4U high, size E4 case, the relay provides instrumentation and fault data with integrated input and output logic, data logging &amp; fault reports. Communication access to the relay functionality is via a front USB port for local PC connection or rear electrical RS485 port for remote connection.<\/p>\n<h2><a
