General Information
HDZG-305 300kV/5mA DC high voltage tester is used for testing DC high voltage for zinc oxide arresters,magnetic blowing arresters, power cables,generators,transformers,circuit breakers and other equipments,which is suitable for electric power branch,power department of factories,scientific research units,railway,chemical industry,and power plants.
Features
- Simple operation and complete function,easy for field work.
- Higher voltage stability,smaller ripple coefficient.
- More reliable and stable,can stay continuous discharge directly to earth.
- High precision,exact measure,figure display,with good anti-interference function.
- High stabilization of voltage regulation.
- Number dial switch for over-voltage set function,which can display figures of voltage clearly.
- For Combined machine design of 40kV equipment,the high voltage can be output directly with earth cable.Other type of equipments can be supplied according to customer’s specific requirements.
