  2SY212-S Synchronism Check Relay

  The 2SY212 synchronism check relay is designed to measure the phase angle between the monitored single phase voltages on the line & bus sides of a circuit breaker & verify that this angle is less than setting. If the measured angle has met this criteria for the time period defined by setting & the voltage magnitudes meet the criteria established by the Live Line/Bus & U/V Line/Bus settings, the output…
