how will i find Transformer rating if supply voltage is 11k.v and how will i find incomer if transformer rating is 12MVA
3 5129Sir, I need a power supply at 380V. The supply I get in three phase is rated 415V. The total supply I have from the supply company is 70KW. Kindly inform if it is better to use a voltage stabiliser for this purpose or a transformer

what is the difference between dry and wet type of 132kV terminations. which one is durable
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
