ASTM D1816 Insulating Oil Dielectric Breakdown Tester

KN-1816 Insulating Oil Dielectric Breakdown Tester

Overview

    KN-1816 Insulating Oil Dielectric Breakdown Tester conforms to ASTM D1816 Standard Test Method for Dielectric Breakdown Voltage of Insulating Oils of Petroleum Origin Using VDE Electrodes, ASTM D877 Standard Test Method for Dielectric Breakdown Voltage of Insulating Liquids Using Disk Electrodes and IEC 60156 Insulating Liquids–Determination of the Breakdown Voltage at Power Frequency. Determination of the breakdown voltage at power frequency Oils that combine a high flashpoint with high dielectric strength have long been used as an insulating medium in transformers, switchgear and other electrical apparatus. To ensure that the dielectric strength of the oil does not deteriorate however, proper maintenance is essential, and the basis of proper maintenance is testing For many electric equipments used in power system and enterprises, inner insulation is mostly oil-insulated. Oil dielectric strength test is one of the essential routine tests.
