The links on this website will be activated after the publication of the Technical Brochures of CIGRE JWG A2/C4.52.

The information is a result from the activities of CIGRE JWG A2/C4.52 High frequency transformer and reactor models for network studies (2014-2022).

Information about the two transformers and the measurements is given in Part E of the Technical Brochure from CIGRE JWG A2/C4.52, downloadable here.

The transient responses described in Part E are downloadable from here.

It is the intention that transformer industry, universities and research institutes make use of this information to develop more accurate and efficient white-box transformer models. The information can also be used by manufacturers to validate their modeling tools.

Any use of the data requires that proper referencing is made to Part E  of the technical brochure and to this web site. No copying of material to another open web site is permitted.
