Overview
Hospitality Enviro Tech circuit current adjustable parameter tester is used for testing the electrical insulation resistance characteristics of large high-voltage transformer, motor appliances, remote power cables or buried cables under the strong interference site such as high-voltage substation and power plant.
Features
- With strong anti-electric field interference ability up to 2 mA (50 Hz)
- It is suitable for 500kV substation without dismantling wire
- It is used to test insulation resistance of 500 kV large-scale transformer
- Short-circuit current is 10 mA
- Suitable for testing high capacity and inductance
- Wide resistance range 0.01 MΩ to 1999 GΩ
- With high-resolution, having accurate readings
- Can smoothly adjust voltage from 0 V to the desired value
- With timing function, remind users to record
- Analyse absorptance and polarization index of measured target
- The key parts are all imported components
- Ensure accuracy and accurate
- One-piece chassis, small size, light weight, easy to carry
- Rugged and strong grinding material, overall texture and longer
Technical Specifications
