WebThe power measurement in three-phase, three-wire circuit is carried out by this method. The connection is shown in the figure. As the neutral wire is common to the three phases, each wattmeter reads power in its own phase, and the total power is given by the sum of the readings of three wattmeters. Total power of load circuit, P 3-φ = W 1 + W ...

Two Wattmeter Method : Construction, Derivation & Its Applications
WebMay 12, 2024 · In order to measure the three-phase power consumed by the load, only one wattmeter is required. But this method is limited for the 3-phase networks with balanced load only. Thus for measuring power in a three-phase network with unbalanced load, two wattmeter method or three wattmeter method is used.

The meter requires the measured device must have neutral wire. otherwise it can't … Web3. To corectly measure power on a three phase system (without neutral) you need two wattmeters. For a purely reactive load, one wattmeter will read positive X watts and the other will read negative X watts meaning the power consumed is X-X watts or 0 watts (as one would expect). You have to remember that the line voltage and line/phase current ... how are mist formed
