Synchronizing breaker

WebThe synchronizing breakers in Figures 16.1 and 16.5 have internal voltage and phase- angle sensors to monitor the site and grid voltages and signal the correct instant for closing the breaker. As a part of the automatic protection circuit, any attempt to close the breaker at an incorrect instant is rejected by the breaker. Webeither fail to detect breaker-flashover conditions or operate too late to prevent extensive damage. As a result, breakers can explode, damaging neighboring equipment or placing substation personnel at risk. Frequently, only one phase of the breaker flashes over during synchronizing procedures.
