GOZ-25 Series Insulation Resistance Tester
GOZ-25 series insulation resistance tester adopts ultra-thin silk sheets header, multiple output voltage, large capacity, strong anti-interference, simple operation, with time prompts. It is the ideal instruments to measure transformers, mutual inductor, generators, high voltage electrical motors, power capacitors, power cables, surge arresters and other insulation resistance. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities’ inspection, and issue a DC high voltage test report.
Also called: high voltage insulation resistance tester, insulation resistance tester, insulation characteristics tester, electric shake table, electronic insulation resistance tester
1. For BO2520A, at 500V the instrument can highest insulation test 20GΩ, at 1000V maximum measurable 40GΩ, at 2500V maximum measured 100GΩ; for BO2550A, at 2500V for maximum measurable 100GΩ, at 5000V maximum measured 200GΩ; for BO2550B, at 5000V for maximum measurable 200GΩ, at 10000V highest measurable 400GΩ.
2. Rated output voltage remains on BO2520A, load resistance can be as low 4MΩ / 8MΩ / 20MΩ; for BO2550A is 20MΩ / 40MΩ; for BO2550B is 40MΩ / 80MΩ, which makes the instrument can accurately measure low insulation resistance.
3. Automatic conversion range is double scale instructions, easy to read with colorful LED display.
4. The instrument adopts ABS plastic enclosure design, with strong anti-jamming capability, compact structure and beautiful appearance.
5. Instrument uses ultra-thin silk sheets header and seismic capability.
