Focused on the complexity and Time-consuming of judging the error wiring of the energy measurement device, It extracts a series of electric parameter tables including phase angle table, such as the voltage sequence table, the line voltage location table, phase angle transform table, and phase angle table. And proposes a simple method of judging the error wiring of Three-phase three-wire error wiring of two components energy measurement device. The method based only on the four tables, inspectors only need to look-up the tables in accordance with the measured dates and get the error wiring instead of drawing vector plots. Because these tables root from vector plots. It greatly simplifies inspectors to judge wiring mistake, improves the working efficiency and makes the test results more accurate.

The aim of this paper is to establish a simple method for the calculation of the transfer function parameters of the capacitor servomotor. The equivalent circuits of a group of twelve capacitor servomotors of widely different parameters are simulated on a transformer analogue network analyser. An empirical formula expressing the reference voltage in terms of the motor speed, control voltage and the capacitance value is obtained. A torque equation for the capacitor servomotor is deduced by introducing the obtained formula in the torque equation of the two-phase servomotor derived by Saleh and Yuferov. The gain and time-constant of the capacitor servomotor are deduced from the proposed torque equation. Effects of the control voltage, as well as the effects of the capacitive reactance on the gain and time-constant, are also discussed. The torque-speed characteristics of a drag-cup capacitor servomotor are computed for different values of the control voltage and different capacitances using the proposed torque equation, and compared with those obtained experimentally. The experimental results are in good agreement with the theoretical calculations.
