Electrical Engineering ⇒ Topic : Applications of Induction Wattmeters

Applications. Due to low accuracy and high power consumption, the characteristics of induction wattmeters are inferior to those of dynamometer wattmeters. For this reason, dynamometer wattmeters are almost universally used for the measurement of a.c. as well as d.c. power. However, induction wattmeters have their chief application as panel instruments where the variations in frequency are not too much
