Patent
5th generation
 
The VLF testers (Generator) are easily
to test cables, transformers, switchgear,
rotating machinery and other
electrical apparatus. 
 


 
VLF Advantage
 
1. Safe Optical isolation technology, 
2. Easiest to use Fully automatic microcontroller
3. H/L voltage closed loop negative feedback control
4Built-in printer
5. Built-in protective resistors                               
6True sine wave output
7Real-time display of actual output waveform         
8Ergonomic, menu guided, large touch colour LCD
9Storage of test results for later retrieval and print.                        
10Over voltage and current protected
11Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz, 0.01Hz
12Data of current, voltage and waveform directly sampled at HV side.
13AC testing does not degrade good cable insulation
14Harmful space charges are not injected into the cable insulation
15No traveling waves are generated during testing
16Rugged and reliable design less prone to failure from transients
17. Invatation Patent                                                    
18. CE mark
19. Portable, 1 Controller + 2 boosters
Each booster can be used separately, there are 1*30KV + 1*50KV
  Booster for 80KV set, using the 30KV booster to test 30KV output, using the 50KV booster to test 50KV output,
  Using 2 boosters in series connection to test 
80KV output.







 
Safety features
    
1. Short circuit protected.
2. Status display of all important safety functions and messages.
3. Safe, easy to use operation with emergency off and key switch lock-out.       
4. Fully integrated discharge circuit to safely ground the DUT after testing.
5. Zero start interlock.
6. Zero voltage switching.
