Synchronism Check Relay

Description Made in Australia
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 the setting & the voltage magnitudes meet the criteria established by the Live Line/Bus &
U/V Line/Bus settings, the output relay will be energised & the breaker permitted to close.
Resetting will occur if either the phase angle or voltage magnitude stray outside the pre-set
limits or if the sync check enable input is de-energised. Front panel LED's provide visual
indication of relay status & sync check function.
Bus or Line U/V, Differential Voltage and Frequency Slip Close block functionality together with
flexible synchronism check bypass logic caters for a diverse range of applications.
