Hypo test, also known as hipot or high-potential testing, is a vital procedure to verify insulation integrity in electrical equipment like transformers, cables, and batteries. By applying high voltage safely, it detects weak spots without causing breakdowns. Wrindu provides OEM and custom hypo test solutions, ensuring reliable, certified, and precise equipment for B2B clients worldwide.
How Is a Hypo Test Performed?
A hypo test applies high voltage—usually 2 to 5 times the equipment’s operating voltage—for a short duration, typically one minute. It monitors leakage current, which should remain below safe thresholds. Wrindu’s machines feature automated voltage ramps, precise micro-amp measurement, and data logging to deliver accurate results for transformers, circuit breakers, and cables.
| Parameter | Standard Value | Wrindu Feature |
|---|---|---|
| Test Voltage | 2x-5x rated | Programmable up to 100kV |
| Duration | 1 minute | Timer with auto-stop |
| Leakage Current | <5 mA | Digital micro-amp meter |
Why Is Hypo Testing Important?
Hypo testing prevents failures by identifying insulation weaknesses early, reducing fire hazards and downtime. Compliance with IEC and CE standards ensures safety in utilities and manufacturing. Wrindu delivers certified hypo test equipment trusted globally, extending the operational life of high-voltage gear and enabling precise OEM customization for specific applications like relays and battery systems.
What Types of Hypo Tests Are Available?
Hypo tests are typically categorized into AC, DC, and VLF (very low frequency) methods.
-
AC Hypo Test: Detects partial discharges under operating conditions.
-
DC Hypo Test: Measures insulation polarization, suitable for motors.
-
VLF Hypo Test: Ideal for long cables, reducing power factor issues.
Wrindu provides all variants with customizable voltages, supporting versatile industrial applications.
How Should You Select Hypo Test Equipment?
Selection depends on voltage range, current accuracy, portability, and required certifications. Transformers may require 100kV+ output; cables benefit from VLF testing. Features such as touchscreen operation, USB export, and 24/7 after-sales support enhance usability.
| Feature | Basic Model | Advanced Wrindu Model |
|---|---|---|
| Max Voltage | 50kV | 200kV |
| Weight | 30kg | 15kg (portable) |
| Price (Wholesale) | $5k | $15k (OEM custom) |
Wrindu’s tailored solutions provide scalable, reliable performance for B2B operations.
What Standards Govern Hypo Testing?
Key standards include IEC 60060-1 for high-voltage testing and IEEE 400 for cable testing. Leakage currents are typically limited to 1–10 mA based on equipment class. Wrindu ensures all devices comply with international rules, passing third-party audits for utilities, OEMs, and research labs.
