  • Abstract
    A direct-reading instrument for the precise calibration of voltage-transformer testing sets of the comparator type is described. The calibrator covers a range of ±11.11% for voltage error and ±411 min for phase error. These quantities are indicated on decade dials with constant resolutions of 0.001% and 0.1 min, respectively. The accuracy depends on the indicated voltage errors and phase errors, but is well within the resolution limits of most commercially available testing sets.
