Which damping is used in Electrodynamometer?Īir friction damping is used, as eddy current damping will distort the weak operating magnetic field and thus it may leads to error. Some voltmeters and ammeters use the electrodynamometer. Can Electrodynamometer run for both AC and DC voltage supply?ĭue to this characteristic of the electrodynamometer movement, it can be used in both AC and DC systems to measure current. Electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power other types are required for radio frequency measurements. The wattmeter is an instrument for measuring the electric active power (or the average of the rate of flow of electrical energy) in watts of any given circuit.
