When a transformer rated meter is changed due to overload, what is this process commonly known as?

The process of changing a transformer rated meter due to overload is correctly referred to as meter replacement. This term captures the essence of the action, which involves removing the existing meter that has become inadequate for the current load and substituting it with a new meter that can handle the increased demands.

In cases where a transformer is under significant load, it may exceed the specifications of the original meter, making it necessary to replace it to ensure accurate readings and safe operation. Meter replacement is crucial in maintaining the efficiency of the power distribution system, as using an outdated or inadequate meter can lead to inaccurate billing, potential equipment damage, and safety hazards.

Meter adjustment refers to recalibrating the meter within its specified range instead of replacing it with one that has a higher rating. Load adjustment might imply modifying the system or reducing the load, rather than directly dealing with the meter itself. Transformer switching typically pertains to changing connections or configurations of transformers rather than the meters associated with them.
