This function checks the voltages upstream and downstream of a circuit breaker and
allows closing when the differences in amplitude, frequency and phase are within authorized limits.
Characteristics
allows closing when the differences in amplitude, frequency and phase are within authorized limits.
Characteristics
- adjustable and independent set points for differences in voltage, frequency and phase
- adjustable lead time to take into account the circuit-breaker closing time
- 5 possible operating modes to take no-voltage conditions into account.
