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...

1. A 380 / 220 V r.m.s. 3-phase 4-wire circuit carries loads of 8 + j8.1 ohm; 4 + j4.1 ohm; and 2 +j2.1 ohmin the three phases respectively. The length of the circuit is 100 m, and the resistivity of the phase conductors is 0.0005 Ω/m. The neutral conductor is of the same size as the phase conductors. a) Select a reference angle 0for the first phase. Then write down the three phase voltages in both polar format and complex number format. b) Make appropriate assumptions, and take temperature effects on resistance is insignificant. Calculate the currents in the three phases. (Note: Determine conductor resistance, and apply Kirchhoff’s Voltage Law) Based on the result, suggest a main switch rating for the circuit. c) Show your preferred direction of neutral current in a diagram, and then determine its value. (Note: Apply superposition principle, and Kirchhoff’s Current Law) Use its magnitude to show that in this circuit, the unbalanced load may increase the voltage drop in some of the phases. (Note: Also observe the common volt drip in neutral) State your assumptions, if there are any. d) Suddenly the neutral wire of the circuit is broken. Estimate the new currents in the first phase, i.e. Phase L1. State your assumptions, if there are any.
