The current transformers (CTs) are very impotant components of a protection system. The most powerful protection relay also will not correctly operates if its CTs are not correctly sized.
The main aim of the CT sizing or validation procedure is to varify both the CT gives a correct measure during normal operation and it does not saturate in case of fault.
M2EC is able both to size and to validate current transformers in compliance of IEC and IEEE standards, by means of in-house made calculation instruments.
