Vlf Tester Vlf Cable Tester Vlf Hipot Tester High Voltage Test Equipment

General Information

VLF Cable Tester is a compact and high performence test equipment which diagnoses the condition of HV and MV cables enables early detection ofA vulnerabilitiesA and prevents potential faults.
Voltage withstand testing is an essential electric test for electric equipment to dertermin the effective of insulation. VLF AC high voltage Test Set 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

lA 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
lA Easy operation: simple connection and easy operation
lA 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.
lA Safety and realiabity: low connection between control unit and HV booster and safely realiable performance.
lA Wide measure range: 0.1Hz, 0.05Hz and 0.02Hz can be selectable which ensures a wide range.
lA Full facilities: capacitive touch screen , big LCD screen , automatic storage and buit-in printer.
lA High low voltage closed-loop negative feedback circuit is adopted.No capacity rising during outputing.
