Product Description

VLF Transformer Hipot Tester AC Hipot Test Set

VLF Hipot Tester Introduction:
This product integrates the advanced technology of modern digital conversion, full microcomputer control, and realizes the automation of boosting, reducing, measuring and protecting. The automatic boosting process can be intervened manually. The design fully complies with the standards of the power industry. At present, mechanical modulation and demodulation of ultra-low frequency signals are generally adopted, there is no standard sine wave, there are measurement errors, and there are spark discharge problems in the high-voltage part. This product can overcome the above shortcomings.

VLF Hipot Tester Features:

1. Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.  
2. Overvoltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself, the actuation time is less than 20ms.
3. Overcurrent protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 20ms.
4. A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside.  

Notes:

• Power supply requirement: AC50Hz, 220V, stability of frequency: fluctuation less than 0.5%.
• When using it, the capacitance of the sample should not exceed the rated capacity of the instrument. The overlow capacitance of the sample will affect the output wave form. If the capacitance is less than 0.05µF, the instrument cannot output normally.
• When using it, it is prohibited to boost voltage without load, or to connect with resistive load.
