Since feb this year my meter hasn’t been working properly. After numerous visits from OVO and now from Western Power I’m told I need to get my own Electrition to find the CT Ration on my meter ??????
However no one seems to know what it is ????? Really???

A CT is a Current Transformer, and is the ferrite core that wraps around your supply cable and sends the reading of what your current consumption is to the meter.
The connection between the CT and a meter is normally 5A. If you have a 100A supply, the CT Ratio is 20:1.
Why you would need any involvement in CT Ratios is a mystery though as most domestic electricity meters are direct connect meters and don't use CTs....
