Phase Meters; Phazor Models 100A, 200A (Industrial Test Equipment CO.)

摘要

The procedure describes the calibration of the Industrial Test Equipment Co. model 100A and 200A Phazor phase meters. The test instrument indicates the phase sense and magnitude of null voltages over a wide range of input amplitudes and frequencies, and simplifies balancing these null voltages to zero when suitable bridge or nulling circuits are utilized.
