oil sample dielectric test gives the insulation rupture
voltage at 26 kv. is this transformer safe to be operated .
The working voltage is 11 kv
Answer Posted / sms
AS PER IS:6792 , Oil Electric break down voltage( BDV) at
room temp using 2.5 mm gap should be Min 30 KV .
Accordingly don't take risk and carry out oil filteration
as early as possible to avoid any break down.
