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 EHV tranm. The conductors are …….. a) Cu roads b) Cu bars with Si c) Cu tube with Si plate

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
