Abstract :
Accurate measurements of core loss for distributed-air-gap magnetic materials have traditionally been very difficult to obtain. Wattmeter measurements are affected by very small phase and time-delay measurement errors, while traditional calorimeters measure the sum of excitation winding loss and core loss. This paper presents an improved calorimeter which excludes winding loss and measures core loss alone
