Product Description
Ultra low frequency insulation withstand voltage test is an alternative method for power frequency withstand voltage test.Using 0.1Hz ultra low frequency withstand voltage test replace power-frequency withstand voltage test, not only is equivalent to the same equipment, and greatly reduces the volume and the weight, so the ultra-low frequency withstand voltage device is widely used in large generators, cables, power capacitor test AC voltage withstand test products.
Feature
1.Advanced technology: using digital frequency conversion technology, microcomputer control, step-up, step-down, measurement, protection and other test processes are fully automated. The instrument has an electronic calendar function, and the time can be maintained after power failure.
2.Comprehensive protection: multiple protections (overvoltage protection, high and low voltage side overcurrent protection), rapid action (action time ≤ 20ms), the instrument is safe and reliable.
3.Safe and reliable: The controller and the high-voltage generator are connected at low voltage, controlled by photoelectric, and are safe and reliable to use.
4.Adopting high and low voltage closed-loop negative feedback control circuit, the output has no capacity increase effect.
5.Complete configuration: 8-inch industrial touch screen, automatic storage, automatic printing.
6.The instrument has a data communication function, and the test data can be uploaded to the computer by connecting with the computer through the USB port.
7.The instrument has a help document function, you can know the usage, wiring, and precautions of the instrument without viewing the manual.
8.The instrument has a system setting function that can modify the current time.
9.Large test range: 0.1Hz, 0.05Hz and 0.02Hz multiple frequency options, large test range.
10.Small size and light weight: very conducive to outdoor operations.
