Rent the High Voltage VLF-65E for Safe and Reliable for Testing

High Voltage VLF-65E 65kV VLF TesterIt is always recommended that electrical equipment be checked for problems even if it seems to be working fine, as electrical stress, normal weathering and contaminants can cause insulators to lose resistivity.

A safe and reliable method for testing insulation is with a VLF hipot. This type of test unit uses an alternating current with a very low frequency of 0.1 Hertz. The low frequency allows for the use of lesser power compared to DC high potential testing. 

The High Voltage VLF-65E 65kV VLF Tester, from HVI, utilizes a dry-type, air cooled, solid state design with microprocessor control.

Its test programming, numerous output functions, wireless communications, and data retrieval are intuitive and easy to learn, as well as its PC Application software.

Portable, and built for the rigors of field use, like all HVI products, the High Voltage VLF-65E‘s 0 – 65 kVac output voltage meets world standards for Acceptance Testing up to 35 kV class cable and its sine wave output is suitable for using optional Tan Delta and Partial Discharge measurement systems.

The High Voltage VLF-65E offers everything needed for fully testing cables rated up to 35 kV.
