DC hipot tester UHV-282

high-voltageportablemulti-point

Product introduction:
The UHV-282 is a fully automatic trip-type withstand-voltage tester designed for insulating boots and insulating gloves. Standard configuration supports simultaneous testing of 2 samples (expandable to 8 channels on request) with independent leakage current monitoring and automatic trip/disconnect per sample. Leakage current sampling and trip control are powered by a DC 12V lithium battery; channel readings are shown on a high-brightness LED module. The equipment features high/low voltage separation and real-time monitoring of voltage, current and test-status at each position to maintain continuity and safety during batch testing.

Product parameters:
Designed for dielectric withstand testing of insulating boots, insulating gloves and similar insulating PPE.

Technical parameters:

• Model: UHV-282
• Support power supply: DC 12V lithium battery
• Rated voltage: 50 kV
• Maximum leakage current range: 30.0 mA
• Leakage current measurement accuracy: ±1% ±3 digits
• Leakage current resolution: 0.01 mA
• Operating ambient temperature: -10 ℃ to 40 ℃

• Channels: standard 2 channels (expandable to 8)

Features:

• Simultaneous testing of 2 samples as standard (customizable up to 8) with independent leakage current measurement per sample.
• Dry test method for insulating boots: small steel balls placed inside the fabric lining to avoid water filling and facilitate drying.
• Leakage sampling and trip mechanism powered by lithium battery; battery level displayed as percentage.
• High/low voltage separation; per-channel leakage current displayed on high-brightness LED module.
• Per-sample automatic trip on breakdown or over-limit leakage current; only the affected sample is disconnected while others continue testing.
• Trip threshold adjustable via front-panel controls.
• Dedicated stainless-steel grounding tray for boots and stainless-steel container for gloves for safe, repeatable operation.

Application Scenarios:

• Factory quality control: routine withstand-voltage testing of insulating boots and gloves to verify compliance with standards.
• Acceptance testing and commissioning: verify insulation performance of newly acquired PPE before use.
• Periodic preventive testing: detect insulation ageing, moisture or degradation on in-service equipment.
• Quality inspection and type testing by manufacturers and test labs.
• Third-party testing and certification laboratories providing compliance data.
• Equipment maintenance and safety management to establish periodic testing programs and reduce insulation-related risks.

Test method for insulated gloves:

• Low-voltage test: preventive voltage 2.5 kV, hold 1 minute; accept if leakage current ≤ 2.5 mA (default threshold 2.5 mA).
• High-voltage test: preventive voltage 8 kV, hold 1 minute; accept if leakage current ≤ 9 mA.

FAQs:

• Q: What happens if one test sample fails? A: The automatic trip function isolates the failed sample while allowing the remaining samples to continue testing, minimizing interruptions.
• Q: Does the equipment record leakage current? A: Yes. The system continuously monitors and displays leakage current per channel during tests.
• Q: Which insulating PPE can be tested? A: Insulating boots, insulating gloves and other rubber insulating products designed for electrical safety.
• Q: Are test voltage ranges customizable? A: Yes. Output voltage ranges can be customized per customer requirements and applicable standards.
