OEM Best Gas Leakage Detection Factory – GDPDS-341 SF6 Electrical Insulation State Comprehensive Analyzer – HV Hipot
General Information At present, the UHV voltage level of 110KV and above uses SF6 gas-insulated enclosed GIS as the main primary equipment of the substation, the evaluation of GIS internal insulation status is mainly achieved by partial discharge detection method and SF6 gas chemical analysis method at home and abroad. When partial discharge occurs in the early stage of insulation degradation inside the GIS, it will cause serious safety hazards to its safe operation. The detection methods of partial discharge mainly include three methods: ultra-high frequency partial discharge test, ultrasonic partial discharge test, and chemical detection of SF6 gas composition. At present, there are separate devices for these types of test methods on the market. For on-site GIS partial discharge li... -
OEM Best Battery Resistance Tester Factories – GDKH-10 Battery Activator – HV Hipot
General Information In all operating equipment and operating network systems with increasing informationization and automation, uninterrupted power supply is the most basic guarantee. Whether it is AC or DC uninterruptible power supply system, the battery acts as backup power source plays an important role in power source system. Usually, the battery is in the state of floating charge standby. Once the AC power is lost or other accidents, the battery becomes the sole energy supplier of the load. We know that in addition to the normal life cycle of the battery, some of the early failure of the battery may occur due to problems such as the quality of the battery itself, defects in materials, structures, processes, and improper use. In order to verify the standby time and actual capaci... -
