In all H.T. Transformers and Circuit Breakers etc. transformer oil or other insulant is a very important ingredient. The liquid insulant used should have a very high dielectric strength. To test the dielectric strength of the insulant, a very high voltage is passed through it. The failure of the dielectric strength of insulant is shown by a spark across two electrodes. This Oil BDV Test Set is a complete apparatus to carry out this test and is manufactured in various voltage ranges and models, as per IS: 6792/1992 and IEC-156.

Applied Techno Products offers the following Oil BDV Testers to meet the wide ranging requirments of its clients:

• Motorized Oil BDV Testers
• Semi - Automatic Oil BDV Testers
• Fully Automatic Oil BDV Testers
