- Sometimes the ring main distributor has to cover large area, in that case voltage drop in some section may become higher than that of its variations limit.
- In order to reduce voltage drop, the distributor are joined through a conductor is called as interconnected distributor.
- Figure shows interconnected type ring main distribution system PQRST.
- The point Q and S of the ring distributor are joined through interconnector QS.
- The solution of this network is done through Thevenin theorem.
Steps
- Open interconnector QS and find potential difference between QS. It is equivalent to Thevenin voltage Vth.
- Calculate resistance viewed form point QS. It is equivalent to Thevenin resistance Rth.
- Join Vth, Rth and RQS is in series.
- Current through interconnector IQS = Vth / ( Rth + RQS )
Advantages
- The main advantages of interconnected type ring main distributor are that the voltage drop at the interconnected point is reduced.
