SYNCHROCHECK
SYNCHROCHECK 1(4)
There are four identical synchrocheck elements available, numbered 1 to 4.
The synchronism check function is intended for supervising the paralleling of two parts of a system which are to be joined
by the closure of a circuit breaker. The synchrocheck elements are typically used at locations where the two parts of the
system are interconnected through at least one other point in the system.
Synchrocheck verifies that the voltages (V1 and V2) on the two sides of the supervised circuit breaker are within set limits
of magnitude, angle and frequency differences. The time that the two voltages remain within the admissible angle differ-
ence is determined by the setting of the phase angle difference
and the frequency difference
F (slip frequency). It can
be defined as the time it would take the voltage phasor V1 or V2 to traverse an angle equal to 2
at a frequency equal
to the frequency difference
F. This time can be calculated by:
(EQ 5.26)
where:
= phase angle difference in degrees;
F = frequency difference in Hz.
