Research on High Voltage Fast Transient Pulse Group Generation Technology for DC Electricity Meters

In order to ensure the metering accuracy of DC electricity meters under complex working conditions, this paper studied the high voltage fast transient pulse group generation technology suitable for anti-interference performance test of DC electricity meters, and proposed a fast transient pulse group generation method based on the fusion mechanism of "series resonance + double voltage rectification + negative feedback regulation". A high voltage fast transient pulse group generation system was designed and verified by experiments. The experimental verification results showed that the output pulse group signals of the DC energy high voltage fast transient pulse group generation system could meet the requirements of GB/T17626.4-2018 standard, the waveform and strength were stable and reliable, which can effectively support the anti-interference test verification work for DC electricity meters.
