Patent ID: 8598742

Claim:
A server in electronic communication with an electricity meter that measures current from a power transformer, comprising: a storage system; at least one processor; and a power transformer detection unit stored in the storage system and being executable by the at least one processor, the power transformer detection unit comprising: a reading module operable to read power transformer data from the electricity meters, the power transformer data comprising a current of the power transformer, the current of the power transformer being equal to the current of a vacuum circuit breaker connected to the power transformer; a determination module operable to determine if a work state of the power transformer needs to be changed from a power-on state to a power-off state upon the condition that a total current of two adjacent vacuum circuit breakers is less than or equal to a predefined maximum current of one of the two adjacent vacuum circuit breakers; and a sending module operable to send an alert message to an alarm computer in response to a determination that the work state of the power transformer needs to be changed from the power-on state to the power-off state.
