摘　　要：为了适应现场各种安装环境下的电压互感器误差自动测量,提出了一种基于WiFi的现场电压互感器误差主动测量方法。该系统利用先进的电力电子技术和WiFi无线通信技术,使程控源、互感器校验仪、负荷箱等设备组成无线通信网络,使用计算机控制代替人工控制实现误差测量,能自动测量升压回路实际负荷,针对串联谐振升压回路还能给出谐振调节参数。该系统实现了电压互感器误差测量数字化、控制网络化、状态可视化,极大提高了现场测量工作的准确性和安全性。In order to adapt to the error test of the field voltage transformer, this paper presents a system to measure voltage transformer error actively based on WiFi, which uses advanced power electronic technology and WiFi communication technology to make the regulator, transformer instrument and load boxes form a wireless communication network, and replaces manual control by computer control. It also measures the actual load of the circuit automatically and gives the adjusting parameters according to the series resonant boost circuit. The system realizes the digitalmeasurement, the network control, the state visualization which greatly improve the accuracy and security of the field measurement.
