Abstract

Arrester is used to increase the reliability of power transfer in the distribution network due to lightning strikes. There are several types of arresters to be developed. A modified multi gap arrester was tested to know its performance. The method used to determine its performance was done by comparing it with metal oxide type arresters through a series of laboratory tests. The testing consists of impulse test, salt fog test, and follow current interrupting test. The arrester performance related to residual voltage, breakdown voltage, and the ability to interrupt follow current were obtained through the tests. By knowing the performance of modified multi gap arrester, it can be used as a consideration in applying this technology related to the insulation stress of protected equipment and the potential for follow current phenomenon.
