A capacitor used to protect the transformer if these any problem in the cct.
A transformer does not normally contain a capacitor. However, you might be thinking of a 'd.c. power supply', which consists of a transformer, rectifier, and smoothing circuits. The smoothing circuits will contain capacitors.
It depends upon at how much voltage level 400 kvar capacitor bank is used.
Use of rvt in capacitor bank
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.

The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
Series reactors may be used in switching in capacitor banks. These are used to minimize the transient voltage spikes on the system resulting from switching in a capacitor bank.

Use of rvt in capacitor bank
by using a resistor or capacitor or transformer
If you are talking about a capacitor bank used for power-factor improvement, then it is rated in reactive volt amperes (var). Otherwise, it is rated in farads (F).
because they decompose easily giving out toxic gases.............AnswerThey are cancer-causing.
A capacitor doesn't step down AC voltage, that's what a transformer does! It really can't, no matter what the circumstances.

Capacitors are used to improve an inductive load's power factor towards unity. The power factor before and after adding the capacitor bank depends entirely on the inductive/capacitive values involved.
