Introduction

    The instrument is used to test specific parameters on field or in laboratory for zinc oxide arrester. It is widely used in on-site inspection (live testing) and laboratory tests (power cut overhauling). It is in line with national standards in DL474.5-92 On-site Insulation Test Implementation Guidelines- Arrester Test.
