摘要：

The controllable metal oxide surge arrester is a new electrical set-up which can deeply reduce switching overvoltage in UHV transmission system. The conventional arrester test method could not be used to validate the switching impulse response properties of the controllable metal oxide surge arrester. Consequently, we discussed the switching impulse response properties of the controllable metal oxide surge arrester, and put forward a new test method which switching impulse current test and switching impulse voltage test were carried out respectively fitting test requirements. Moreover, we verified the response delay of controllable switch and the residual voltage of controllable metal oxide surge arrester in the test. The parallel modulated wave capacitor was used in the existing residual voltage test circuit to implement the switching impulse current test method, the impulse voltage generator, regulator and measurement circuit were used to implement the switching impulse voltage test method, and a designed 110 kV controllable metal oxide surge arrester was used in the verification test. In the test, the controllable arrester could respond reliably under switching impulse voltage. By comparing with the conventional arrester, the decreased range of the residual voltage of controllable arrester was close to the designed controllable rate of 25% in the same current. Furthermore, the designed controllable arrester with expected limit effect was verified, and the availability of the approach was verified.
