CT Metering Panels

Metering for bulk and high-current supplies

CT (current transformer) metering panels meter high-current supplies where direct metering is not possible. NPE builds the CT chamber with the correct CT ratio, test terminal block and sealed metering compartment for the tariff.

The panel houses the metering CTs on the incoming busbar, the meter and its test block, and the sealing arrangement the utility requires, coordinated with the main switchboard incomer.

Frequently asked questions

How is the CT ratio chosen?

From the maximum demand and the supply rating, so the meter operates in its accurate range; we confirm against the KPLC application.

Can existing switchgear be adapted?

Often yes — a CT metering chamber can be added to an existing main board if there is room and the busbar allows CT installation.

Is a check meter supported?

Yes, a check or sub-meter with its own CTs can be included for tenant billing or energy monitoring.

Who seals the meter?

The utility applies the final seal; we provide the sealing points and the metering test records.

When in doubt, put safety first
