Description
Ultra-low frequency high voltage generator test is an alternative testing method for the power frequency withstand voltage test.
It's mainly used to test large capacity electric items, like electric motor, cables. This test system combines modern advanced digital various frequency technology, controling by microcomputer, step-up, step-down, measurement, protection function all fully automatic, allowing manual intervention during step-up. Owe to the full electronic designing, this testing device has excellent characteristics of small volume, light weight, large LCD screen display
(clear and intuitive), displaying the output waveform, self-contained printer outputing all testing reports.Major Composite parts: controling host, booster, compensate capacitor(optional)
Main Features: 1. Current, voltage, waveform all gathered form the high-voltage end, so they are accurate.
2. Over-voltage protection: the device will stop working and begin to protect when output voltage exceeds setted limiting voltage, action time <20ms.
3. Over-current protection: double protection for high and low voltage. The high-voltage end(primary end) will go on protecting according to setted value; the low-voltage end(secondary end) will stop working and begin to protect when this end's current exceeds rated current, action time <20ms.
4. The high-voltage output protective resistor is built in the booster, so it doesn't need to connect other resistors.
5. Utilizing high and low voltage closed loop inverse feedback control circuit, the output doesn't have a capacity rising effect.Technique Parameters:1.Output Power: 0.1Hz, 0.05Hz, 0.02Hz
