Abstract
An apparatus may include a controller configured to periodically generate a control signal at a first logic level to initiate a continuous built-in test for a generator control relay (GCR) switch. The apparatus may also include a GCR switch control circuit configured to determine when the GCR switch will not have a current flowing therethrough and generate a GCR switch control signal to open the GCR switch responsive to the control signal. The apparatus may further include a voltage monitoring circuit configured to monitor a voltage across the GCR switch when the GCR switch is opened and compare the monitored voltage to a threshold value. The voltage monitoring circuit is also configured to generate a first output value indicating the GCR switch has passed the continuous built-in test or a second output value indicating the GCR switch has failed the continuous built-in test.
