A Hipot Tester (short for "High Potential Tester") is a critical piece of electrical safety testing equipment used to verify the insulation strength of electrical products. Also known as a Withstand Voltage Tester, it applies a high voltage between a product's live parts and its accessible surfaces to ensure no breakdown occurs under stress.

• Safety Assurance — Prevents electric shock hazards to end users
• Product Reliability — Identifies insulation weaknesses before market
• Regulatory Compliance — Meets IEC, UL, VDE, and other global standards
• Liability Prevention — Reduces risk of product recalls and lawsuits

1. Output Voltage Range: Low voltage (0-5kV AC), Standard (0-10kV AC), High voltage (0-15kV+)
2. Current Measurement: Breakdown current typically 0-5mA, 0-10mA, or 0-20mA
3. Test Duration: Adjustable: 1s, 2s, 5s, 10s, 30s, 60s
4. Arc Detection: Advanced hipot testers detect arcing events for partial failure identification

Home Appliances: Refrigerators, washing machines, air conditioners, vacuum cleaners

Electronics: Power supplies, adapters, computer peripherals, chargers

Wiring & Cables: Power cables, extension cords, wire harnesses

Medical Devices: Patient monitors, diagnostic equipment, therapeutic devices

Automotive: Wire harnesses, EV charging equipment, in-vehicle electronics

Q: What is the difference between hipot tester and megohmmeter?

A hipot tester applies high voltage to test insulation strength under stress conditions. A megohmmeter (megger) measures insulation resistance at low voltages. Hipot testing is more comprehensive for safety validation.

Q: How often should hipot testing be performed?

Production line: 100% of products. Quality control: random sampling per batch. Design validation: during R&D and certification phases.

Q: Can hipot testing damage products?

If properly set up within specifications, hipot testing is non-destructive. However, products with manufacturing defects may fail and should be rejected.
