Summary:In this paper, the calculus measurement system measuring fast transient overvoltage (VFTO) is analyzed and the parameters of each part of the system are calculated by theoretical calculation. The circuit is simulated by ATP-EMTP and the waveform of the result is compared with the ideal case, which shows that the response is affected by the stray parameters. To reduce the system error, two optimization schemes are proposed in this paper. First, the shielded electrode is replaced by the arch shield electrode in order to reduce the ground capacitance, and the possibility of creeping discharge and partial discharge. Second, resistors in series and capacitors in parallel are used to reduce the effect of residual inductance and residual inductance. The simulation results show that the effect of stray parameters can be effectively reduced.
