Brushes are used in Exciter to facilitate current in
revolving rotor where Field winding is placed. In generators
for Rotor earth fault and as earth to remove any static
current induced in the rotor.

To prove the capacity of a 10MVA transforemr with 6.5% impedance by a short circuit test how much power is needed to inject an impedance voltage if we have to arrive for its rated current?
