Product Description
Product overviewWith the rapid development of China power industry, electrical preventive experiment is an important aspect of electrical power system safe operation and maintenance work. Insulation diagnosis is an important tool to detect the in sulation or fault of electrical equipment
Currently, electrical equipment (such as transformers, generators, etc.) toward the trend of large capacity, high voltage, structural diversification and sealing, this requires insulation resistance tester with advantages of large capacity, strong anti-interference ability, easy to carry and so on. So we designed and developed the series meter especially for strong interference field test for large high voltage transformers, electrical appliances, remote power cables or laying cables and other electrical insulation resistance properties for high-voltage substations, power plants and others.
The instrument system combines analog circuits, digital circuits, mechanically operated advantages, achieved a leading position at the output voltage, output current, measuring range, measurement accuracy, anti-interference ability.
Products features1,With strong anti-electric field interference ability up to 2mA (50Hz), it is suitable for 500kV substation without dismantling wire to test insulation resistance of 500kV large-scale transformer 2,The short-circuit current is 10mA, be suitable for testing high capacity and high inductance 3,Wide resistance range: 0.01MΩ ~ 1999GΩ. With high-resolution, having accurate readings
4,Wide output voltage range: 0.1kV, 0.25kV, 0.5kV, 1kV, 2.5kV, 5kV, adjustable, you can smoothly adjust voltage from 0V to the desired value
5,With timing function, remind users to record, and analyze absorptance and polarization index of measured target
6,High quality: The key parts are all imported components, to ensure accuracy and accurate 7,Easy to use: one-piece chassis, small size, light weight, easy to carry
8,Look beautiful: rugged and strong grinding material, the instrument's overall texture and longer lifeTechnique parameters1. Technique specificationsMode | Test voltage | Voltage accuracy | Short-circuit current |
