High Voltage Surge Generator | Cable Fault Locator | XHHV515-8L
Product Description
This XHHV515-8L The device integrates DC high voltage source, energy storage capacitor, discharge ball gap and so on. The device completely replaces the traditional test transformer, operating box and pulse energy storage capacitor weighing hundreds of kilograms (generally 5kVA a set of transformers more than 60 kilograms, control box more than 30 kilograms, pulse energy storage capacitor more than 20 kilograms). The power supply adopts high-precision, high-stability special high-voltage electronic components and high-frequency high-voltage technology, which makes the whole machine simple structure and ultra-light weight. In order to retain the habit of using transformer and operating box to produce DC high voltage, the pulse generator adopts humanized design operation mode, which is safe and reliable. Really do not break the impact effect, high voltage to the ground short circuit can also work normally. At present, it is the lightest and most humanized portable DC impulse high voltage equipment. It is an ideal product for power cable fault detection.
Applications & Target Audience: Engineered for municipal distribution network maintenance crews, low-voltage industrial plant electrical teams, commercial property electrical contractors, and rural electrification maintenance units that perform impulse discharge fault testing and DC withstand voltage testing on 10kV and below power cables.
