SEL-352-1, -2 Instruction Manual 

 

Figure 3.21:  Flashover Condition Logic, Scheme 1–Six PTs 

Scheme 2 (Flashover, Three Potential Transformers) 

Scheme 2 uses the voltage on one side of the circuit breaker and the current through the breaker 
to detect flashover.  This logic also needs the breaker monitor input.
