Product Details

 

 

Description

This generator is sutable for 35kV and below voltage level standard full-wave lightning impulse voltage test of large capacity power transformers, 

CT/PT, reactors, arrester, switch, casing, insulator and other test objects.

 

This generator is only applied for indoor environment, the abient temperature 10 ℃ ~ +40 , relative humidity less than 90%, not more than 1000 altitude,

insulation surface should be dry, ten the the generator can be used normally.

 

Technical parameter

 

1. Rated voltage 300kV

2. Voltage class rating: 100kV

3. Rated energy 12kJ

4. Total Impulse capacitance: 0.26uF

5. Single pulse capacitor 1.56.μF/50KV × 2, 3 sets)

6. Load capacitance 500 ~ 30000pF

7. Measured output impulse voltage waveform

1). 1.2/50us full-wave lightning impulse voltage, voltage efficiency >85%

2). 100/1000; operating wave, voltage efficiency >70%, impulse voltage waveform parameters 

      and their deviations are in line with the IEC and GB311-97 State standards.

3). Working continuous time: 

continous running if charging and discharging 1 time every 90 seconds over 2/3 rated voltage; 

continous running if charging and discharging 1 time every 45 seconds under 2/3 rated voltage.
