HYG-10KVA/150KV Intelligent High Voltage Breakdown Testing Device is an advanced intelligent voltage withstanding test equipment designed in accordance with the latest national power industry standard GB/T 1408.1-2006/IEC 60243-1:1998 to replace GB/T 1408.1-1999 (issued from 2006-11-09 2007-4-01 implementation) electrical strength test method for insulating materials (Part 1: under-power frequency test). It is used for various electrical products, electrical components, and components. Insulating material and so on carries on the insulation strength test under the stipulated voltage, in order to examine the product's insulation level, discovers the insulation defect of the tested product, and measures the ability of overvoltage. It is widely used in electrical manufacturing department, electric power operation department, scientific research institutes and universities.
