Abstract:
1. A monitoring system for detecting a short circuit condition in a switching subsystem being used in a bypass input of a power supply, in which the bypass input also includes a circuit breaker in communication with the switching subsystem, the monitoring system comprising: a voltage monitoring subsystem for monitoring a voltage across at least one component of the switching subsystem and generating a first output signal in accordance therewith; and a processor responsive to the first output signal from the voltage monitoring subsystem that compares a voltage value of the first output signal with a predetermined threshold signal and generates a second output signal based on the comparison, the processor further adapted to consider a state of the circuit breaker in communication with the switching subsystem, and to use the state of the circuit breaker and the second output signal to determine whether at least one of a short circuit condition and an open circuit condition exists with respect to the switching subsystem.
