High-voltage hipot tester UHV-280

multi-pointDCAC

Product introduction
UHV-280 is an automatic AC withstand voltage tester designed to perform dielectric strength and leakage current tests on insulating boots, insulating gloves and related protective tools. The system comprises a control console, 8-position test rack, oil‑immersed booster (test transformer) and optional accessories (electroscope racks, insulating rod rack, grounding trays). It supports simultaneous testing of up to 8 samples with independent trip per channel and anti‑interference wireless leakage transmission to the console for centralized monitoring and recording.

Product features

• Simultaneous AC withstand voltage and leakage current measurement for up to 8 boots or gloves with individual per‑sample readings.
• Dry boot test method using small steel balls — eliminates water filling and simplifies post‑test drying.
• HV/LV separation and anti‑interference wireless transmission of leakage data to the control console for improved operator safety.
• Independent trip/breaking mechanism per channel: a breakdown or over‑limit leakage on one sample does not interrupt other channels.
• 7‑inch TFT touchscreen showing test voltage, 8‑channel leakage currents, calendar, timing and prompts.
• DC/stepper motor controlled booster for fully automatic voltage ramp, hold, timing and shutdown; test results and leakage traces are saved automatically.
• Dedicated stainless‑steel grounding tray for boots and dedicated stainless‑steel container for glove tests for safe, repeatable setup.
• Adjustable transformer ratio to match customer transformers and application requirements; built‑in overcurrent protection.

FAQ

• Q: Why test insulating boots and gloves with withstand voltage? A: To detect insulation degradation (aging, wear, moisture, contamination or damage) that can cause leakage or breakdown and pose shock risk.
• Q: What items can be tested? A: Primarily power‑frequency AC withstand voltage testing of insulating boots and gloves; with appropriate fixtures, some other insulating tools can be tested.
• Q: What if one sample breaks down during a test? A: The channel's independent trip isolates the failed sample automatically so other samples continue testing.
