0.1HZ Digital Very-low-Frequency High Voltage Tester
The new generation of AC withstand tester, replacing harmonic withstand tester, is widely used in AC withstand test of large capacity equipments such as generator, cable, insulator, power capacitor, large transformer etc. Not only can it be the first choice of on-site and outdoor testing, but also as the ultra-low frequency source.
Advantage of 0.1Hz SVLF series1,Small volume, light weight, easily to operate. Theoretically speaking, the capacity is of 1/500 of power Frequency.2. AC ultra-low frequency tester doesn’t form tree-clearance in the insulating condition.3. Unlike DC test, it’s uneasy to destroy cables; meanwhile the capacitance effect of testing articles has no influence to it.4. Pernicious polarization charge would make no way to dielectric during the testing.
Features of function1. Adopting digital convention technology and microcomputers controlling system make the testing process completely automatic.2. The large screen of liquid crystal and Chinese input operating system insure that testing wave-form (Sinusoid Wave) can be displayed; testing reports can be printed.3. Auto-protection of over-current and over-voltage, the research,design and manufacture of independent intellectual property rights according to power standard4. Multi-frequency selections (0.1Hz,0.05Hz,0.02Hz) strengthen the load-bearing capability.
Technical parameters:1. Output voltage ratings: 30KV, 40KV,50KV,60KV,70KV, 80kV,90KV2. Output frequency: 0.1Hz, 0.05Hz, 0.02Hz3. Measurement accuracy: 3%4.
