How to take Transformer oil Break down voltage test?
Answer Posted / v.b.vijay anand
At first thing you maintain the electrical norms..To Take one sample from top of Transformer and one from the
bottom of transformer.
On before take oil samples you should confirm the moisture particles removed are not..
And then removed the air boubles in that vessel between the electrode...
The BDV of oil should withstood min 50 KV...
The gap between the test sample is 2.5mm maintained..
Voltage should be gradually increased from 0.
You will wait min 30min then only you will get good result..
