3 Phase Current Transformer Wiring Diagram
3 phase current transformer wiring diagram for 3 phase load (ampere) testing. As you know that we use the current transformer to measure the current. For testing the current (ampere) running to load we use two types of amp meters. Which one series type is wired in series between load and supply. And 2nd is a current transformer type which is wired with a current transformer to measure the current. We can wire a current transformer for a single phase and also for 3 phase. The current transformer is always used for line ampere testing. For 3-phase system ampere testing every Line has its own current transformer. And these current transformers are further connected with a 3-ampere meter or one-ampere meter and ampere testing selector switch.

How to 3-phase current transformer wiring diagram with ampere meter
Note that if your ampere meter is 100/5A then used only 100/5A ratio current transformer. In the below 3-phase current transformer wiring diagram with amp meter. 3 CT coil and Amp testing meters are shown. The current transformer wiring for each meter.
You can wire the current transformer for a three-phase system as shown in the above diagram. However, if you want to test 3 phase ampere with the only one-ampere meter. Then use an ampere selector switch with the current transformer. For that, you need to wire all 3 current transformers with an amp selector switch. And from the selector switch, the two-wire supply will go to the ampere meter. From the selector switch, you can test at each line(phase) ampere.
Why is the one point of ammeter/ct connected together with each other.
