Power consumed by three phase resistive load by two wattmeter method.
Two wattmeters are sufficient to measure total three-phase power.
The wattmeter method is used to measure power in a three-phase load. The wattmeter readings are 400W and -35W. Calculate the total active power.
The input power to a three-phase load is 10kW at 0.8 Pf. Two wattmeters are connected to measure the power. Find the reading of higher reading wattmeter.
The current coils of the two wattmeters are connected in
A wattmeter is connected as shown in the figure.The wattmeter reads-
In the two-wattmeter method of 3ϕ power measurement, if the phase sequence of the supply is reversed:
What is the reading (in kW) of both the wattmeter, when measuring the power of a three-phase three-wire system having an input of 5 kW and power factor of 0.866?
At which angle in two wattmeter method, one wattmeter shows zero readings
If the reading of the two wattmeters is equal and opposite while measuring power in a 3-phase induction motor then the power factor of the load will be
The two wattmeters used for the measurement of power input read 50 kW each. What will be the readings of the two wattmeters if the power factor is changed to 0.8 leading keeping the total input power same?
