Abstract :
We describe two new methods of calibrating a 100-kV Park divider, fitted with N/10 taps. They prescribed a series of automated measurements using (i) a digital conductance comparator, and (ii) a set of full-bridge circuits configurable entirely from the divider sections. Self-heating effects were studied systematically under PC control. Preliminary measurements determined the 1/10 ratio to /spl plusmn/25 ppm.<>
