VIF Very Low Frequency Test Set

The new generation of micro-computer 0.1Hz ultra-low frequency hipot test set overcomes many shortcomings of the first generation of mechanical products, and its performance-price ratio is much higher than that of similar imported products. It is especially suitable for the voltage withstand test of electrical equipment with large insulation equivalent capacitance (e.g. power cables, power capacitors, large and medium generators, motors, etc.).

By using the latest power electronic components and micro-computer technology, the size and weight of the equipment are further reduced, and the performance is more stable with simple operation, which overcomes the shortcomings of short service life, high failure rate and large volume of the first generation mechanical booster. Through years of practice, feedback from a large number of users shows that 0.1Hz Ultra-Low Frequency and High Voltage technology is in the lead in the country, with the highest cost performance ratio.

Products Characteristics

1. Easy to operate: simple wiring, foolish operation.

2. Comprehensive protection: multiple protection (over-voltage protection, high and low voltage side over-current protection), fast action (action time < 20ms), safe and reliable instrument.

3. Safe and reliable: controller and high voltage generator, low voltage connection, photoelectric control, safe and reliable use.

4. The closed-loop negative feedback control circuit with high and low voltage is adopted, and the output has no Capacity-Lift effect.

5. Complete configuration: 8 inch industrial touch screen, automatic storage, automatic printing.

6. The instrument has the function of data communication. The test data can be uploaded to the computer by connecting with the computer through the USB port.

7. The instrument has the function of helping documents. It can know the usage, wiring and matters needing attention without looking at the instructions.

8. The instrument has the function of system setting and can modify the current time.

9. Wide test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, wide test range.

10. Small size, light weight: very conducive to outdoor work.

Products Parameters

1. Power: 220V±10%，50±5%Hz.

Note: If the portable generator is used for power supply, the output voltage and frequency of the generator are required to be stable (generally, the power is greater than 3kW, the frequency is 50Hz, the voltage is 220V ± 5%). Otherwise, some auxiliary measures should be used to stabilize the output of the generator.

2. Output Voltage Accuracy:

    Peak Instability of Output High Voltage: ≤1%

    Frequency instability of output voltage: ≤3%

   Output Voltage Waveform Distortion Rate: <5%

3. The instrument has the functions of power off and sudden shutdown during operation without burning the booster and main engine.

4. Use environment: temperature - 100C ~+400C, humidity ≤ 85% RH

50KV as example
