WebABSTRACT. An accidental energization occurs whenever an offline generator is unintentionally connected to the power system. Generator damage reported from these incidents has ranged from none to the complete distraction. The simplest form of accidental energization is an erroneous closure of the generator breaker. WebInadvertent Energization Protection (27, 50, 60, 81U, 62 and 86) Protects against closing of the generator breaker while machine is not spinning / on turning gear Caused by operator error, breaker flash-over, control circuit malfunction Two schemes illustrated: Frequency supervised overcurrent Voltage supervised overcurrent.
