CT wiring diagram

[Knobhead]

if you were the dishonest type there's a few ways of making it read slower than it should!

I was going to mention that earlier but thought better of it ;-)

 

[Bobster]

Not really sure all I know is they want me to do all the wiring and they install the meter to the front of the CT chamber box. At the end of the day i have no interest in making it read slower all I want is to get paid and move on the the next job. Just wish they would have drawings of exactly what they need to see. Ie do I drill the hole in the front of the chamber for the meter to mount? If so how big and where would they like it. What size fuses do they need to de rate for connection to the meter. surly it can't be that hard to get the info together.

I release you would't, it was just a coment on EON putting trust in other people. Just to add I wouldn't condone anyone doing this, and won't explain how on an open forum.

The only real way you can proceed is to find out what type of meter they would like to use.

This is happening a lot now especially in ukpn. although the ongoing ownership of the CT chamber, CTs and test block is the dno many are not charging for this as part of the new connection but passing the responsibility onto the customer. The meter operator is only responsible from the test block onwards so they often won't help with what's not their problem.

I’ll bet they’ll be interested in the CT chamber when their income is affected.

Sorry

Will try again!

Is the meter EDMI as it's EON?

 

[Stu1312]

The meter type won't make much difference as its the wiring on the ct side of the test block that needs to be installed, providing that is correct the meter operator will be responsible for all connections from test block to meter.

 

[Leesparkykent]

They could provide a diagram though.

Thanks Tony

Stu’s drawing will work, but they won’t accept two cores in a terminal block.

The whole idea of a test block is so things can be tested and isolated safely.

I’ve only worked on MV metering test blocks where the VT could be isolated by inserting insulated plugs on the voltage test block.

 

[Knobhead]

I use Red Yellow Blue Black simply because Brown Black Grey Blue can’t be seen on screen.

This is what EON will expect to see. G/Y is not used for the CT S2 connection to the test block.

Hi guys, I have the exact same query and would like to see if there are any drawings for the connections.... all the links seem to be dead links.

Any help would be appreciated
