3 Overview

Transformer Calibrator is a measurement of power frequency voltage (or current) proportional error of the instrument while working electrical calibrator , Differential pressure (or differential current) is applied to the loop error voltage (or voltage (or current) is applied to the test circuit voltage (or current) Flow), the calibrator can be obtained differential pressure (or differential current) phase through a bridge line, electronic circuits, digital circuits or measuring The amount with respect to the operating voltage (or current) relative to the amount of in-phase and quadrature components, can be obtained by calculation are compared Voltage (or current) relative to the amount of the operating voltage (or current) phasor amplitude ratio (ratio of the difference) and phase. If Comparing a voltage (or current) relative to the amount of lead working voltage (or current) phasors, the phase difference is positive and negative hysteresis. From the measurement principle, calibrator Electrical and electronic can be divided into two categories. Electrical bridge formula by measuring line, Need for balance adjustment of the bridge. Electronic through electronic circuits or digital circuits result of the measurement with digital display Shown, it may have a range of automatic conversion function. Measurement indication calibrator has three representations. Under normal circumstances the ratio of the difference in percentage (%), with a phase difference [Angle] minute ( '); or the ratio of the difference in percentage (%), the phase difference with PCT radians (crad); or the ratio of the difference 10 The negative exponential power (10-n), the phase difference in radians multiplied by a negative exponential power (10-nrad) 10 in.
