Bus is the equipment where the voltage is constant.DC
transformer converts dc voltage from one level to another
level.surge absorber is used to absorb the transient change
in flow of current or rise in voltage due to switching or
lightning.CT ratio is calculated by the ratio of input
currnt to the output current,same for PT.

In case of a synchronous generator carbon brushes, some brushes expire before the others. Why is so? When all the brushes are installed at the same time, why don't thee expire at the same time?
