The power in three phase, which is equal to √3VLILcos Φ.
Three phase Power Measurement Methods
It can be measured by these following methods:
- By single wattmeter of single phase,
(i) when neutral is available,
(ii) when neutral is not available. - By two wattmeters method.
- By three wattmeters of single phase method.
- By one wattmeter of three phase method.
