Research and Designment of Un-Touched Phase-Detecting Sensor for High-Voltage Line
Phase and frequency are two important parameters of the industrial-frequency AC signal. Especially in the following situations such as the highvoltage electric power system, mergence of new power networks, before new transformer stations putting into production, after the expansion of power transformer projects and the overhaul or alteration of main equipments and so on.Phase-detecting are more frequently and importantly required at the scenes of completion and commissioning. Therefore, the paper proposed a untouched phase-detecting sensor for the high-voltage power lines. The sensor is developed in the full hardware method based on digital-to-analog circuit and moreover equipped with wireless communication interfaces. Not only can it facilitate remote transmission of the phase information, but also can be widely applied in the power industry such as measurement of high-voltage wire phase, phase detecting, voltage measurement and electricity detection.
