Features and Benefits
The VLF-65E is a top performer from the latest generation of HVI VLF AC hipots using an air-cooled, solid state design with microprocessor control. Test programming, data retrieval, and custom PC software are intuitive and easy to learn. This unit is portable, affordable, and designed to withstand years of field use.
Its 0 – 65 kV AC peak/0 – 46 kV AC RMS output voltage meets world standards for acceptance testing up to 35 kV class cable, and its sine wave output pairs easily with optional tan delta and partial discharge measurement systems.
