What you are asking for? Are you talking about the distribution transformer installed near your home? if it is, this transformer is called step down transformer which is isolated from primary winding. It has four points (legs) for its secondary winding which is connected in STAR. This STAR configuration is used for un-balanced load condition as the load curve for residential area is continuously changes. The STAR point of three secondary windings must be connected with ground so that if the LIVE wire of distribution network touch with ground via human body or else, the related MCB or RCCB must be tripped other wise circuit would not be completed.
