Design of Active Measurement System for Voltage Transformer Error Test

Abstract – In order to adapt to the error test of the field voltage transformer, solve the problems of the current measuring method, this paper presents the way of using computer control instead of manual control to measure voltage transformer error actively based on WiFi, automatic measure the actual load of the boost circuit, real-time monitoring of the circuit parameters and protection control. At the same time, It realized the whole process information management of measured data, from automatic colletion, analyze to saving, greatly improve of the safety and the efficiency of the work.
