Abstract
A system for indicators of power meters.
Claims9
A power meter comprising:
- (a) said power meter including an enclosure having an exterior;
- (b) said power meter capable of receiving a first voltage input signal, a second voltage input signal, and a third voltage input signal representative of voltage levels in a respective first conductor, a second conductor, and a third conductor;
- (c) said power meter capable of receiving a first current input signal, a second current input signal, and a third current input signal, representative of current levels in a respective said first conductor, said second conductor, and said third conductor;
- (d) said power meter determining a first power factor associated with said first voltage input signal and said first current input signal, a second power factor associated with said second voltage input signal and said second current input signal, and a third power factor associated with said third voltage input signal and said third current input signal;
- (e) said power meter including a first phase status observable from said exterior of said enclosure that indicates said first power factor, a second phase status observable from said exterior of said enclosure that indicates said second power factor, and a third phase status observable from said exterior of said enclosure that indicates said third power factor.

A method of metering an electrical characteristic of a system comprising:
- (a) providing an electrical phase checking apparatus, the electrical phase checking apparatus comprising:
- (i) a first voltage sensor;
- (ii) a first current sensor;
- (iii) a first non-binary indicator connected to said first voltage sensor and first current sensor, said first non-binary indicator configured to indicate a phase separation between a voltage waveform measured by said first voltage sensor and a current waveform measured by said first current sensor;
- (iv) a second voltage sensor;
- (v) a second current sensor;
- (vi) a second non-binary indicator connected to said second voltage sensor and second current sensor, said second non-binary indicator configured to indicate a phase separation between a voltage waveform measured by said second voltage sensor and a current waveform measured by said second current sensor, wherein the apparatus further comprises a first voltage probe connected to the first voltage sensor, a first current probe connected to the first current sensor, a second voltage probe connected to the second voltage sensor, and a second current probe connected to the second current sensor;
- (b) attaching at least two of said probes to at least one wire in said system;
- (c) reading a non-binary indication output by at least one of said binary indicators;
- and
- (d) detaching at least one of said at least two of said probes and attaching it to a different wire in said system in response to said reading.
