Advantages of Hipot Tester

Preventing electrical hazards: The primary purpose is to ensure that insulation is sufficient, preventing electrical shock hazards for end-users.

Identifying weak points: It uncovers hidden flaws such as nicked/crushed insulation, inadequate creepage and clearance distances, and poor spacing.

Non-destructive testing: When used correctly, it is a non-destructive test that validates insulation without damaging the product, unlike "breakdown" tests.

Both polarities: Tests both polarities of insulation simultaneously.

Features of Hipot Tester

Over-voltage protection

The instrument will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.

Over-current protection

Design for dual protection of high and low voltage, downtime protection can be accurately set in high-pressure side. it will be shut down for protection and the action time is less than 20 ms when the current of low-voltage sides exceeds reacted current.

Application of Hipot Tester

Production Line Safety Testing

Ensures that newly manufactured electrical products (appliances, consumer electronics) meet safety standards and do not have insulation defects.

Insulation Integrity Check

Verifies that insulation between energized parts and ground can withstand high voltages without breaking down.

Cable and Wire Harness Testing

Validates that custom cables and wiring harnesses have no short circuits or insulation faults, preventing shock hazards.

Industrial Equipment & Motor Maintenance

Tests insulation in motors, transformers, and industrial machinery to detect degradation over time, helping to prevent equipment failure.

FAQ

Q: What is the purpose of a Hipot test?

A: It ensures that insulation can withstand high voltage for a short duration, guaranteeing safety during normal, lower-voltage operation.

Q: What types of faults can a Hipot test detect?

A: It detects insulation breakdowns, excessive leakage currents, improper grounding, and short circuits.

Q: What is the difference between AC and DC Hipot testing?

A: AC Hipot tests can detect insulation degradation more accurately, while DC Hipot tests are better for testing large capacitive loads and are less likely to cause damage from charging currents.

Q: How often should a Hipot test be conducted?

A: It is a crucial part of production line testing. It is also used in maintenance to test equipment after repair.

Q: Is Hipot testing safe?

A: It is considered the most dangerous electrical safety test, requiring safety measures like insulation mats, gloves, and proper warning signs to protect operators.

Q: What are the common test durations?

A: Production line tests usually last between 1 to 3 seconds, while type tests (or laboratory tests) can last for 60 seconds.
