We are currently working with a shunt single phase energy meter. Can anyone please tell , when the shunt is connected with a meter ,what are the functionality of the three pins of a shunt ?

I shall appreciate an urgent reply.

Thanks

The shunt is used to meausure current accurately.Its value is very small in micro ohms. The 2nd and 3rd pins are used to measure the current.The first pin is connected to the voltage circuit of the meter to avoid circulating currents of the power supply.
