Instrument transformers for metering purposes must have a high degree of accuracy up to class 0.

Understanding Current Transformer Accuracy Classes | Victor Fehlberg’s Tech Postings

Hence, it is essential to inspect and calibrate those instrument transformers at regular intervals. Instrument transformers for protection purposes supply protection relays and must also function accurately at a multiple of 660044-6 nominal current.

A regular inspection should ensure that instrument transformers, together with the connected relays, react quickly and correctly in the event of a fault and guarantee the highest possible security of supply.

The importance of transformer tests is often underestimated.

Risks such as confusing instrument transformers for metering and protection, or mixing up connections can be reduced significantly by testing before initial use. At the same time, damages to the interior of an instrument transformer, caused for example during shipping, can be recognized 6044-6.
