Why star connection does not get short circuited ?

   

  Hello guys, today we are going to discuss about an interesting question. Why star connection does not get short circuited ?

    Before the discussion , lets see what is short circuit and what is the cause of sc in a electrical system.

Definition: 

A short circuit is an abnormal condition in an electrical circuit where the electrical current flows through shorter pathway instead of following the circuit. 

Let's discuss in a simple way . 

Consider one phase and one neutral ,

Case I : connect them via a load ( it may be resistive, capacitive or inductive) 

 circuit will work under normal condition and the electrical energy passing though the resistor will be liberated in the form of heat in case of bulb without any short circuit .

Case II : connect them ( P and N ) without any load .

 Short circuit will happen

  From this , We understand that if phase and neutral are directly connected without any resistance or impedance between them, short circuit occurs.

Same thing will happen about 2 different phases ( for example , R and Y phase ).
