Assignee: TYCO ELECTRONICS (SHANGHAI) CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G  Y | IPC G

Claim 15:
16. A power monitor system, comprising:
at least one power monitor, each power monitor including:
a current/voltage transformer;
an electric energy meter connected in series with the current/voltage transformer;
a first current regulating element and a second current regulating element connected between the current/voltage transformer and the electric energy meter, the current/voltage transformer connecting the electric energy meter to a load to monitor the electric energy consumed by the load, when a current flowing from the current/voltage transformer to the electric energy meter is greater than or equal to a threshold current, at least one of the first or the second current regulating elements reduces the current to less than a rated maximum current of the electric energy meter, each power monitor for monitoring the electric energy consumed by the corresponding load; and
a first switch element and a second switch element switch element, each switch element selectively connects a corresponding one of the first and second current regulating elements in series between the current/voltage transformer and the electric energy meter;

at least one data transmission unit, each connected with a corresponding power monitor to receive and transmit data signals related to the electric energy monitored by the power monitor;
a database server receiving the data signal from each data transmission unit and analyzing the data signals through data fusion to obtain electric energy data associated with each load; and
a display device connecting with a database server and displaying the obtained electric energy data.
