What is the purpose of the capacitor in this transformer circuit?
The capacitor provides a more serious connection to ground for AC, while the resistor only a weak connection for DC to avoid ground loops. Note that since this connection to ground is halfway thru the primary of the transformer, the magnetic field caused by the common mode voltage across one half the winding is offset by the magnetic field ...
What is Transformer? Working Principle, Circuit Diagram
The main transformer tank and some portion of the conservator tank are filled with oil. This oil should not be exposed to the atmosphere directly because it may absorb the moisture and dust and may loose its electrical properties within a very short time. i.e., when the temperature changes, the transformer oil expands or contracts and there is a displacement of air.
