Wiring Connection
This current transformer must be fitted andconnected in the correct way, or the meter will not be accurate. The currenttransformer is marked on two sides, that is ‘P1’ and ‘P2.’ ‘P1’ must face the mains side and ‘P2’ must face the load side. ‘S1’ must be connected to the main side of themeter and ‘S2’ to theload side. Please refer to appropriate wiring diagram of the meter so as to installthe current transformer correctly.

What is the difference between a moulded case current transformer and a split core current transformer?
A split core current transformer is manufactured with the steel core in twopieces. This enables the core to be separated and allows you to fit the coresaround the cable without disconnecting the cables. The disadvantage of splitcore current transformer is that it is larger than standard mould case and the price is approximately four times more expensive.

The optimum load of a CT
The load of current transformer should ideally be about 80% of the normalrunning load, thus a 20% allowance of increase of the load is allowed in thefuture.
