WIRELESS SYSTEM FOR MEASURING VOLTAGE DISTRIBUTION OF ARRESTER

摘要

A wireless system for measuring voltage distribution of arrester acquires the voltage of each node of the arrester synchronously by a wireless transmission method. The voltage of a transformer can be measured by a host(2), and the acquisition of the voltage is only at an interval of 0.6ms with the acquisition of the voltage of the node of the arrester by each voltage measuring probe(1), so measuring accuracy cannot be influenced. A discrete Fourier transform method is applied in signal processing to analyze and calculate the acquired voltage signal. An interference harmonic wave is filtered and base wave voltage is accurately calculated to ensure the measuring accuracy.
