Metering System Audit Service
A metering system comprises the meter, instrument transformers (CTs and VTs), cabling and seals. As a metering system is the point of transaction between two parties it is important that it should accurately reflect the flow of energy. Therefore in most parts of the world regulatory authorities mandate periodic testing and certification of energy meters.
Many different metering technologies are in current use, some of which may be subject to variations in performance with the passage of time. Some of the components of the metering system are vulnerable to tampering or accidental damage or incorrect connection.
We offer an on-site testing service for metering systems, using portable test equipment appropriate for the international standards for energy meters. We check the meter, the instrument transformers, cabling and seals. This gives the energy supplier and consumers faith in the billing and settlement system.
A utility was struggling to optimise the utilisation of the numerous distribution transformers in their system.
By using the information and recommendations provided by our comprehensive distribution transformer study, the utility could improve the reliability of supply to their consumers and plan the maintenance of the DT system.
