Model ATOTS-100 -Oil BDV Test Set

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.
