Abstract
In order to study the waveform characteristics of the transient radiation field produced by the operation of disconnector, the radiated electric field generated by the operation of disconnector in the 330 kV Switching station is measured and analyzed. First, an electric field measurement system based on optical fiber is developed. Then very fast transient overvoltage(VFTO)radiation field generated by operation of disconnector on the different side is measured in the switch station. The measurement results are analyzed both in time domain and frequency domain. The results show that amplitude of the electric field generated by the operation of disconnector at 3 m away from the disconnector can reach 4.65 kV/m. The radiated electric field has a spectrum below 200 MHz, especially in some characteristic frequencies. The VFTO radiation field generated by the operation of disconnector on the busbar side and outgoing line side has different spectrum distribution. The VFTO radiation field generated by the opening and closing operation of disconnector has different spectrum distribution.
