High Voltage Test Kit / Dry Type Testing Transformer/ Hipot Tester
Product Features

GTB series adopts the new technology of coil winding epoxy vacuum pouring and CD type iron core. Comparing with the same kind of oil immersed transformer, it obviously reduces the weight and volume, improves the insulation strength and the anti humid range in the quality, and effectively weakens the magnetic leakage. The transformer is strong enough to withstand short-circuit current impact.

This series of devices are suitable for the power system and the electric power users to test the insulation performance of various electrical equipment in the field, or working as high voltage source.

Small and light, with compact structure, no oil leakage, no maintenance , simple wiring.



Working principle:


The input voltage of this series of products is 200V (400V). By changing the input voltage according to the need of electromagnetic induction principle, the output high voltage can be continuously adjusted from zero volt to the highest rated value.In the DC withstand voltage and leakage current test, as long as the high voltage . silicon stack is rotated in the high voltage output terminal, the input voltage can be

changed, thus obtaining different values of DC high voltage output
This series of products is shown in Figure 1 in detail.

( Figure1)




When used as cascade, its connection is shown in Figure 2.

Technical indicators:


1. Output voltage waveform: sine wave
2. Output waveform distortion rate: less than 1%
3. No load loss: 0.2% to 0.35%
4. Induced voltage withstand: 1.1* rated voltage /1min
5. Short-circuit impedance of the single test transformer: 4.5%~12% (±10%).
6. Voltage adjustable accuracy: ± 1%.
7. Voltage instability: < 1%
8. Over voltage protection function.
9. Surface temperature rise: < 55
10.Permitted continuous operation time of 0.5 hours at rated capacity
11. Continuous running time:≤10kVA:within 2 hours interval,allowing
continuous operation for 0.5 hours.≤15kVA,each interval of 4 hours,
allowing continuous operation for 0.5 hours.
12.At half rated voltage and half rated current, running continuously for 4 hours.

Specification as following, can be customized



Operation Conditions:
1. Ambient temperature: 0 ~ 40
2. Altitude: <2000m
3. Relative humidity: <85%
4. No gas, steam, chemical dust and other explosive and corrosive media
which seriously impact the insulation
