The article has been designed in this articleA new distributed PMU device used in the wide area measurement system of distribution network. Acquisition of a high-density induction module from the line
The power is supplied to the device, and the circuit board (PCB) Roche coil is used to measure the line current, and the space capacitance pressure sensor is used.
The current line voltage measurement, through distributed synchronous sampling to realize the acquisition of the voltage and current of the whole network, is the research of the new distribution network line PMU.)
