Abstract
At least one monitoring element may be configured to sense a current drawn by equipment being monitored from at least one power source and produce a monitoring signature representing the sensed current. At least one sensor may be configured to output a detection signal in response to a change in a monitored condition. At least one circuit element may be placed in series between the at least one power source and the equipment being monitored. The at least one circuit element may be configured to couple the at least one power source and the equipment being monitored by default and decouple the at least one power source from the equipment being monitored in response to receiving the detection signal. The monitoring signature may include a feature representing the change in the monitored condition in response to the at least one circuit element decoupling the at least one power source from the equipment being monitored.
