Hello Sandeep,

I can mention some IMP points to check while installing CT/PT.

1) Use the proper winding group

2) Check the Billing Factor

3) In CT case the CT transformer would eb controlling device

4) Check the measurement type for this device

5) Check the allocation at register level.

6) Enter MR without forgetting.

Hope this will help you out.

Thanks Sachin

But my query is something different, Ok

I will liked to ask another way, whether Billing related CT installation is commonly or not as I have not tried it in a system. what is a general choice whether CT should be install billing related or technically install ...

Hello Sandeep,

The CT is technically installed.

Hope this solves your query.

Hi Sachin.

Thanks for your prompt reply !!!

My one query based on observation, pls correct me if I am wrong...

If CT and meter relationship is one as to one then Billing related installation seems to be correct

I have tested in system, when CT is installed technically then it is available and can also attached to another

device of same installation where in one as to one relationship is not maintain (Business requirement)  and

chances of wrong MF  are there. I am considering Electricity business here.

What are you trying to achieve by doing a billing install for a CT?

We are an electric utility and have CTs technically installed as a "master" device (can be 1, 2 or 3 CTs per installation), and the electric meter (technical and billing installation) is linked to that CT master device, and that determines the billing factor for the meter, the CT per se is not billed.
