Product Details

1.Product Name:

Very Low Frequency Tester VLF-30

 

2.Equipment Description:

The VLF testers (Generator) are suitable for

Testing cables, transformers, switchgear,

Rotating machinery, and other

Electrical apparatus.

 

3.Main Functions:

1. Easiest to use Fully automatic microcontroller

2. Built-in printer

3. True sine wave output

4. Real-time display of actual output waveform

5. Ergonomic, menu guided, large backlit LCD

6. Storage of test results for later retrieval and print.

7. Over voltage and current protected

8. Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz

9. Data of current, voltage and waveform directly sampled at HV side.

10. AC testing does not degrade good cable insulation

11. Harmful space charges are not injected into the cable insulation

12. No traveling waves are generated during testing

13. Rugged and reliable design less prone to failure from transients

 

4.Technical Parameters:

1. Input: 220 ± 10% Volts AC, 50/60 Hz, single phase.

2. Output-Voltage. 30KV

3. Output frequency: 0.1Hz, 0.05Hz, 0.02Hz.

4. Stability of frequency: Fluctuation < 0.5%

5. Measurement accuracy: ± 3%.

6. Positive and negative voltage peak errors: ≤ 3%.

7. Voltage waveform distortion: ≤ 5%

8. Construction: In two units: Controller and Booster...

9. Ambient conditions of use: Temperature Indoor and outdoor: -10ºC to + 50ºC.

10. Humidity: ≤ 85%
