di-electrical strength of transformer oil is 40 kv /minute ,
so due to insulating property it will not get shock at any time.

Answer / durgadas

It is not a elctrical conducter..

Answer / santoshvarma

Transformer oil will have a dielectric strength of more than
40KV at normal conditions, because of impurities or moisture
the dielectric strength deteriorates and come down, f it
comes down the transformer will be short circuited( primary
and secondary windings) and will be busted until that there
is no case of getting shock for a human body

Answer / makudeshwaran

At the time of maintenance,
if the di-electric strength of the oil is more,there is
no shock
if the di-electric strength of oil is very low,there is
a chance to get electric shock

Answer / hareesh

Oil is having a insulating property so by touching the oil how can u getting shock? there is no shock by touching oil

Answer / sunmoorthy

This X fmr oil it's have specific di- electric strength normally 40kv/min so when this value gone down at that time x fmr safety circuit will be trip the x fmr breaker other wise no chance to get shock...

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.

A simple Question from all.... If Voltage drops then its rated value what will be effect on a Residential load? similarly if voltage rises from its rated value then what will be effects on a load? i know if voltage drops the equipment or device draws more current then its rated what are other reasons ? thanks in advance for ur time.......
