| Abstract: | On the basis of analyzing the existing calculation method of tower impulse grounding resistance, a portable test device for impulse grounding resistance is designed. While injecting the slow front wave and low amplitude current into the grounding network, the test device collects the voltage and current signals of the grounding network. After filtering and converting of the data, voltage response under lightning current and impulse grounding resistance are obtained. The test results both in lab and on-site show that this device is reliable and convenient in operation. |
