Assignee: TE CONNECTIVITY SOLUTIONS GMBH
Field: Measurement (Instruments)
Classification: CPC G  Y | IPC G

Claim 18:
19. A power monitor, comprising:
a current/voltage transformer;
an electric energy meter connected in series with the current/voltage transformer, the current/voltage transformer connecting the electric energy meter to a load to monitor the electric energy consumed by the load;
a first switch element switchable between a first state and a second state, in the first state the first switch connecting the current/voltage transformer directly to the electric energy meter; and
a first current regulating element including a first inductor arranged in series between an output of the first switch element and the electric energy meter, wherein in the second state, the first switch element connects the first current regulating element in series with the current/voltage transformer and the electric energy meter, the first switch element switching from the first state to the second state when a current flowing from the current/voltage transformer is greater than or equal to a first threshold current, the first current regulating element reducing the current to less than a rated maximum current of the electric energy meter.
