Difference between Electrodynamometer Wattmeter and Low Power Factor Wattmeter
Electrodynamometer wattmeter and Low Power Factor (LPF) wattmeters are mostly similar in construction and operation, except for the following modifications are carried out in the electrodynamometer wattmeter to convert it into a LPF wattmeter: Pressure coil resistance is kept low to increase the torque. Compensating coil is used to compensate the Pressure coil current. Capacitor … Read more
