D-dot场式电压传感器试验系统
Simulation system of field voltage sensor based on the D-dot sensor
摘要
Abstract
The conventional voltage sensor measures voltage through the energy transfer by the core.While,due to the saturation magnetization of the core,the band response of measurement becomes narrow,and ferromagnetic resonance over-voltage appears.We presented a D-dot sensor for voltage measurement,introduced its working principle and designed a new type of voltage sensor test system to test its precision and accuracy.The D-dot sensor is connected with the collection terminal on the ground through the wireless network of hardware system,composing of ground simulation test system.The capture terminal can receive,process and analysis signals with LabVIEW technology.A test platform was built to simulate the voltage transformers in wire line of 10 kV voltage.The results show that the D-dot sensor has high precision and fast response,and the simulation system is stable and reliable.关键词
