Relay Testing

SYNC-Monitor

The SYNC-Monitor is the ideal tool for checking the operation of paralleling devices and synchronizers which use frequency and voltage adjusters. During a test the systems to be synchronized are simulated using the voltages of the test set. The amplitude and the frequency of the test values can be changed manually or via the control commands of the synchronizer. During a test, the test values and the voltage, frequency and phase difference between the voltage to be synchronized and the reference voltage are displayed numerically in real-time in the SYNC-Monitor display. In addition, the phase difference is also displayed graphically in the synchroscope. The evaluation of measured values is performed automatically immediately after a test. A table displays the test values at test begin, at the time the switching command is issued and at the time the circuit breaker closes, taking into account the operating time of the circuit breaker.
