split core Transformer Vs ordinary transformer

[Hameedulla-Ekhlas]

Greeting all,
I was reading one datasheet regarding to split core transformer. In data sheet in the feature of split core is written like this

"This split-core current transformer was designed for easy installation on large bus or
wire conductors in order to make electrical load surveys or for continuous monitoring of
current."

Here is the link.

I have two questions regarding this.

1- what is the difference between the ordinary CTs and split core CTs?
2- Is really designed only for easy installation on large bus or it has any other special feature that ordinary CTs doesnt.

2- Is really designed only for easy installation on large bus or it has any other special feature that ordinary CTs doesnt.

Nope, that's it.

Nope, that's it.

I got two following answers from another friend,

1.The difference is the split core. That's it. Because of this minute separation there will always be a microscopic air gap in the split core making it less efficient and less accurate than a solid care.

2. It can be installed over an existing conductor without disconnecting it.

2. It can be installed over an existing conductor without disconnecting it.

I think it is also worth noting that a bad split core transformer can be removed and replaced without disconnecting the conductor.
