Very low frequency HV generator asthe new generator of AC withstand voltage tester, replacingresonant withstand voltage tester, is widely used in AC withstandvoltage test of large capacity equipments such as generator, cable,insulator, power capacitor, large transformer etc. Not only can itbe the first choice of on-site and outdoor testing, but also as theultra low frequency source.
Advantage:
1. Small volume,light weight, easily to operate. Theoretical speaking, the capacityis 1/500 of power frequency.
2. AC ultra lowfrequency tester doesn't form tree-clearance in the insulatingcondition.
3. Unlike DC test,it's uneasy to destroy cables; meanwhile the capacitance effect oftesting articles has no influence to it.
4. Perniciouspolarization charge would make no way to dielectric during thetestinFeatures:
1. Adopting digitalconversion technology and microcomputer controlling system make thetesting process completely automatic.
2. The large liquidcrystal screen insure that testing wave-form (sinusoid wave) can bedisplay, testing reports can be printed.
3. Full protection:multiple protection (over-voltage protection, over-currentprotection), prompt action (action time≤20ms), the device safe andreliable.
4. Multi-frequencyselections (0.1HZ, 0.05HZ, 0.02HZ) strengthen the load-bearingcapability.
5. Safe andreliable: the controller connect with HV generator, photoelectriccontrol, safe and reliable.
6. Adopts high andlow voltage closed-loop negative feedback control circuit, outputwithout capacitance-raised effect.
