Do Easily 3 Phase Energy Meter Connection.


Energy Meter is a very useful and important measuring instrument. The energy meter is a device by which we can measure electrical energy. The energy meter is Integrating measuring Instrument. Today we are going to know "3 phase energy meter connection" which is a very important topic in electrical engineering that you should know.

Identification of terminals of 3 phase energy meter :


Count terminals from your left-side to write-side.
  • Terminal '1'- Input of 'R' phase
  • Terminal '2'- Output of 'R' phase
  • Terminal '3'- Input of 'Y' phase
  • Terminal '4'- Output of 'Y' phase
  • Terminal '5'- Input of 'B' phase
  • Terminal '6'- Output of 'B' phase
  • Terminal '7'- Input of Neutral 
  • Terminal '8'- Output of Neutral

3 Phase Energy Meter Connection with Neutral Wire:

Many people become confused when they are going to connect the three-phase energy with the load which does not need Neutral. 
There are many 3 phase energy meters does not need neutral but many 3 phase energy meters are there which have need neutral even the load does not need Neutral wire. So read the details of the 3 phase energy meter provided by the manufacturer company when you going to connect.


3 Phase Energy Meter connection with a 3 phase motor:

As we know most of the three phase motors does not need neutral for their operation. So, here you can see we just connected three phases only. Practically, there is no application where a three phase motor is to be directly connected to an energy meter. Here, just an example that if neutral is not connected with load then also energy meter can measure.
