VLF cable testing is a compact and high performence test equipment which diagnoses the condition (Conducting diagnostics) of  HV and MV cables enables early detection of vulnerabilities and prevents potential faults ( breakdowns).

A withstand voltage testing is an essential electric test for electric equipment to determine the effective of insulation. VLF hipot tester proceed withstand voltage testing on HV and MV cable from frequency 0.01 Hz to 0.1Hz . It is applied to test electrical equipment with large capacitance such as large generator, motor and power cable.

Feature

• Advanced technonlogy:  Adopt the technology of digital variable frequency and micro-computer control.It realizes the fully automatic voltage boost,step-down,measurement and protection as well as the manual intervention in the process of automatic voltage boost
• Easy operation: simple connection and easy operation
• Multiple Protection : overvoltage protection and overcurrent at high-low voltage side protection, fast action (Action time is no longer than 10ms) and realiable test equipment.
• Safety and realiabity: low connection between control unit and HV booster and safely realiable performance.
• Wide measure range: 0.1Hz, 0.05Hz and 0.02Hz can be selectable which ensures a wide range.
• Full facilities: capacitive touch screen , big LCD screen , automatic storage and buit-in printer.
• High low voltage closed-loop negative feedback circuit is adopted.No capacity rising during outputing.
