VLF-6022CM Very Low Frequency AC Hipot Tester

The VLF-6022CM is a high-performance VLF AC hipot tester designed for precise, efficient testing of medium- and high-voltage cables and electrical equipment. Ideal for power utilities, electrical contractors, and service professionals, the VLF-6022CM delivers reliable diagnostic and withstand testing in the field or lab with user-friendly operation and robust portability.

Key Features & Benefits

High-Voltage Output for MV/HV Applications – Provides up to 62 kV peak (44 kV RMS) output, suitable for testing cables rated up to 35 kV and above.

0.1 Hz Sine Wave Output – Uses a very low frequency (VLF) 0.1 Hz sinusoidal waveform, minimizing stress on cable insulation while ensuring effective and compliant testing.

Automated Test Sequences – Built-in programmable test routines, including withstand and timed tests, simplify operation and reduce testing errors.

Data Storage & Reporting – Internal memory allows for automatic storage of test results, with easy export options for reporting and record-keeping.

Lightweight & Rugged Design – Portable and durable build, ideal for demanding field conditions and remote job sites.

User-Friendly Interface – Simple navigation, clear display, and intuitive controls for seamless operation in various environments.

Safety First – Designed with comprehensive safety features including emergency shut-off, HV interlock, and overvoltage protection to ensure operator safety.
