Introduction
---Advanced 30/50/80/120 kv VLF Very Low Frequency Tester For Cable Withstand Voltage Test Equipment
Ø VLF Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.
Ø Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test. It is much smaller, lighter and portable than power frequency withstand voltage tester. It is proved home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.
Ø It can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment
Ø 1. advanced technique: adopts digital inverter technology, microcomputer control, fully automated test;
Ø 2. Easy to operate;
Ø 3. Full protection: multiple protection (over-voltage protection, over-current protection), prompt action (action time≤20ms), the device safe and reliable;
Ø 4. Safe and reliable: the controller connect with HV generator, photoelectric control, safe and reliable;
Ø 5. Adopts high and low voltage closed-loop negative feedback control circuit, output without capacitance-rised effect;
Ø 6. Completely equipped : LCD, auto save and print data;
Ø 7. Wide measurement range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection;
Ø 8.Small in volume, light in weight: benefit to field tests
