Description
Overview
80 kV 0.1 Hz VLF AC Hipot Tester for 50 kV Cable Testing GAOTek combines the advanced technology of modern digital conversion, fully computer control, automated boost, buck, measurement and protection human intervention can be carried out during the automatic set up process. Main advantage includes fully electronic, small sizes and light weight, large screen LCD (clear and intuitive), printer output test report, easy to use designed to fully meet the power industry standards. Mechanical approach are widely used for modulation and demodulation ultra low frequency signals but no standard sine wave, some error of measuring and spark discharge in high pressure part etc.
Features
- Advanced technology using digital frequency conversion technology, microcomputer control, fully automated test processes such as boosting, bucking, measurement, and protection
- Convenient operation, simple wiring, fool-like operation
- Comprehensive protection multiple protections (overvoltage protection, high and low voltage side overcurrent protection), rapid action (action time ≤ 10 ms), and the instrument is safe and reliable
- The high and low voltage closed-loop negative feedback control circuit is adopted, and the output has no capacity rise effect
- Complete configuration capacitive touch screen, LCD Chinese character display, automatic storage, automatic printing
- Large test range 0.1 Hz, 0.05 Hz and 0.02 Hz multi-frequency selection, large test range
- Small size and light weight
