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.4 metering performance requirements4.1 accuracy class Press transformer calibrator accuracy class is divided into Level 1, Level 2 and Level 3. 4.2 basic error 4.2.1 In table 1 of reference conditions, the ratio of the error manually-range calibrator each range shall not exceed Formula (1) limits given phase error shall not exceed the formula (2) given limits. Table 1 The basic error of reference conditions Ambient temperature Relative humidity Power frequency Voltage and current percentage Power waveform The distortion factor Environmental Field Disturbance 0 ℃ ~ 40 ℃ ≤80% 50Hz ± 0.5Hz 20% to 120% / 5% to 120% ≤5% No more than the minimum scale value 1/2 or quantized values ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 169-2010_English be delivered?Answer: Upon your order, we will start to translate JJG 169-2010_English as soon as possible, and keep you informed of the progress.
