Primary Current Injection Test Sets

A primary current injection test set injects a powerful current on the primary side of protective relay equipment or current transformers to determine how the system will react, then record how long the current remains live before breaking. Current injection testing is essential to electrical system maintenance, as circuit breakers can go a long time without being activated.

ATEC rents primary current injection test sets from leading manufacturers such as SMC, OMICRON, and Megger.
