FAQ

Q: What is a High Voltage Hipot Test System?

A: A High Voltage Hipot Test System is equipment that applies controlled high voltage to electrical insulation to verify dielectric strength and detect insulation weaknesses.

Q: What products can be tested with a Hipot System?

A: Typical test objects include transformers, cables, switchgear, motors, generators, electrical assemblies, bushings, and other insulated electrical equipment.

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

A: AC testing is commonly used for dielectric withstand testing of many electrical products. DC testing is often used for specific insulation evaluations and cable applications. VLF testing is mainly used for medium-voltage cable testing where lower frequency AC testing is preferred.

Q: How do I choose the correct Hipot Test System?

A: Selection depends on the equipment type, required test voltage, testing standard, working environment, automation requirements, and data recording needs.

Q: Can Hipot Test Systems be integrated into production lines?

A: Yes. Systems can be configured with automatic control, digital data recording, communication interfaces, and customized testing procedures for manufacturing environments.

Q: What safety functions are important for high-voltage testing?

A: Important safety functions include emergency stop, safety interlock, overcurrent protection, overvoltage protection, grounding checks, and automatic discharge.

Q: Can the test system be customized for different voltage requirements?

A: Yes. The system configuration can be adjusted according to voltage range, current capacity, test object size, and application requirements.

Q: How often should Hipot Test Systems be calibrated?

A: Calibration frequency depends on usage conditions, internal quality procedures, and applicable requirements. Regular calibration helps maintain measurement accuracy and reliable test results.
