Checking Calibration of factory incomer electricity meter

[Inteificio]

I've been asked to confirm that our site electricity meter is accurate!
Easy on a small site, but 6 cable feed,and a few thousand amps, leaves me short on ideas.

To confirm, this is the meter that records electricity usage for our bill.
It's a CT style. The meter doesn't give a live power read.


The feed is parallel cable to our busbar, so nowhere to clamp easily.

Frankly, I'm short of any ideas that are either safe, accurate or don't involve cutting tags off.

Has anyone got any cunning ideas short of getting out EDF to check?

Is this site metered on the HV side of the transformer?
If so, this is not a diy check. Call out the experts

To be fair I'm not 100% sure. The CT link goes underground to their building.

The fact I hadn't even considered that makes me realise I should keep a mile away from this. Not my skill set. It's been a long time since I've played with HV, I'd like to keep it that way.

I'll get them in to check the meter and do downstream logging on our site to compare weekly totals.

Anyone got any better ideas?

What has prompted the request?
Has there been a sudden increase in kwh useage or is the bill just higher due to increased charges?

IMO job for the large power boys of the appointed energy company.

No change, just head office sending down pointless tasks to keep me overworked.
