OMICRON CT Analyzer - now with RemAlyzer!

Software based tool to determine CT residual magnetism

The operation of protection devices is affected by the performance of current transformers (CTs).  They must be accurate during normal and fault conditions.

CT Remanence is the amount of residual magnetism left in the iron core due to faults with DC offset.  High residual magnetism can lead to mis-operation of the protection system, especially for protection with auto-reclosing function. 

Knowing the level of residual magnetism in a CT after a fault can help in post-fault analysis.  It can also be important to know this value in order to assess proper CT application and sizing. 

The RemAlyzer can provide this measurement safely and perform any routine CT testing after removing it.
