The T4500 Auto Synchronizer for Conventional Governors
The SELCO T4500 Auto-Synchroniser provides automatic synchronisation and connection of a generator to a live bus bar.
The T4500 measures the voltage across two phases on either side of the circuit breaker in order to obtain data on frequency, phase and voltage deviation.
The T4500 will automatically adjust the speed of the generator (through the governor) in order to match the frequency and phase to the live busbar. Two built-in relays provide the increase and decrease pulses for a conventional governor. The strength (width) of the pulses is proportional to the frequency/phase deviation. The E7800 Motorised Potentiometer can be used to adapt the contact pulses to a signal suitable for the speed trim input of an electronic speed controller.
The T4500 will continuously adjust the generator speed until frequency and phase is within limits. The signal to close the circuit breaker is issued just before phase accordance is obtained. This is done in order to compensate for the circuit breaker make time.
