3 Overview

Single-phase meter phase is the phase difference between the current and the voltage of the AC circuit for measuring the frequency of the same special instrument, Single-phase phase phase angle table into tables and power factor meter depending on the measurement function. Phase angle meter for measuring the same frequency AC current and voltage phase angle difference between the phase angle is indicated, showing the value in degrees (°); power factor meter For measuring the phase angle between current and voltage cosine, indicated that the power factor, dimensionless.

4 metering performance requirements

4.1 accuracy class Single-phase phase meter accuracy level is divided into seven levels 0.5,1.0,1.5,2.0,2.5,3.0,5.0 each Basic error should not exceed the level specified in table (single-phase basic error phase error table is represented by reference) 1. 4.2 basic error 4.2.1 The basic error of the phase angle of the table Table 1, the level of accuracy and basic error limit Accuracy class 0.5 1.0 1.5 2.0 2.5 3.0 5.0 Basic error limit/(%) ± 0.50 ± 1.0 ± 1.5 ± 2.0 ± 2.5 ± 3.0 ± 5.0
