Power Cable High Voltage Test Laboratory

For Power Cable High Voltage Test Laboratory, function will be carry out type test and routine test for power cables.
The below drawing show the systems for 35kV ~ 132kV. 
To this voltage level power cables, we will use tank type inductance resonant test system with bushing output and with different taps for multiple voltage output at rated power. Quality factor for such kind of system are normally low. Low as 10. 

Cable test terminations and injection capacitors are normally necessary. 

But to higher voltage cables, we will proposal cascade inductance resonant test systems, single modules or two modules. For tanks type inductance resonant test system, maximum voltage we have tried is 500kV, it heavy and not easy moved. If cascade with epoxy tube design will be much more convenient.
 
 
The triangle structure of the capacitors can save much room for user. 

Cable test termination and power test oil test terminations are available:
 
 
 

For power cable tan delta  test, it will invole capacitance & dissipation factor bridge and gas insulated standard capacitor
 
 

Impulse voltage test system will be another important test system for power cable:
 
 
To 35kV power cable, I think above impulse voltage generator is enough, but to a much higher voltage power cable, there will need bigger impulse voltage generator:
 
 
The above are HIVG 1200kV and HIVG 2400kV impulse Voltage generators. Please be noticed: in 1200kv impulse system, there listed the multiple chopping gap, its an option item. If test cable only, you will not need this component.
