ages—up to severalhundred thousand volts—the construction is relatively simple andcheap, and no auxiliary potential transformers are required forreducing the voltage to be measured. It has the disadvantage ofsmall ratio of torque to weight of moving parts, so that errors dueto friction of the… … Fig. 70.
