HMCOP-60kV VLF Hipot Tester Connection Description Video
Product Overview & Applications
The HMCOP-60kV Ultra-Low Frequency Tester is a high-voltage diagnostic instrument specifically designed to evaluate the insulation integrity of medium-voltage electrical equipment. This device generates an alternating voltage at an extremely low frequency (typically 0.1Hz), enabling the application of stress to insulation layers under safe conditions. It effectively simulates power frequency operating conditions while significantly reducing energy consumption.
q: What is a VLF Tester and what does "60kV" mean?
A:A VLF (Very Low Frequency) Tester checks electrical insulation health. The "60kV" means it can generate up to 60,000 voltsat very low frequencies (0.1Hz) to test equipment rated up to 35kV class.
Q: What types of equipment can I test?
A:Perfect for:
Underground power cables(up to 35kV)
Transformers, generators, and motors
Switchgear and circuit breakers
Industrial plant electrical systems
Q: What's the difference between Withstand Test and Tan Delta Test?
A:Withstand Test:Pass/fail check - does insulation break down under high voltage?
Tan Delta Test:Health check - measures insulation quality and detects aging
Q: How long does a typical test take?
A:Quick check:15-30 minutes
Full diagnostic:60-90 minutes
Depends oncable length and test type
Q: What safety precautions are critical?
A:Alwaysde-energize and ground equipment before testing
Alwaysuse insulated gloves and safety barriers
Neverbypass safety interlocks
Alwaysverify discharge before handling
Q: Can it locate where a cable is damaged?
A: No.It tells you ifinsulation is bad, but you need a separate Cable Fault Locatorto find the exact damage location.
Q: What power supply is needed?
A:Standard 220V outlettypically suffices. For remote sites, a portable generator(3-5 kVA) works.
Q: How often should I test my equipment?
A:
New installations:Before energization
Routine maintenance:Annually for critical assets
After faults:Immediately following electrical incidents
