Patent ID: 11933824
Assignee: TYCO ELECTRONICS (SHANGHAI) CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G  Y | IPC G

Claim 0:
1. A power monitor, comprising:
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, the monitor operative such that when a current flowing from the current/voltage transformer to the electric energy meter is greater than or equal to at least one of a first or a second 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, 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.
