High Voltage VLF Hipot Tester
High Voltage VLF Hipot Tester Brief Introduction
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.
Features
1. Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.
2. Over-voltage protection: the instrument will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.
3. Over-current protection: design for dual protection of high and low voltage, downtime protection can be accurately set in high-pressure side. Shut down to protection times is within 20 ms when the current of low-voltage sides exceeds reacted current.
4. High-voltage output protection resistor design in the body boost and it is no need to additional outside resistor.
5. Closed-loop negative feedback control circuit of high and low voltage.
