CTDim is a tool for current transformer (CT) and voltage / potential transformer (VT / PT) selection and dimensioning. By optimizing the selection of CT or VT data with respect to technical requirements of power system protection and/or metering, engineering and production costs can be substantially reduced while maintaining technical excellence.
A CT and VT burden check avoids extensive under-burdening of instrument transformers and helps when specifying instrument transformers. The latest international instrument transformer standards are taken into consideration.
Enjoy savings in engineering and production costs by optimizing the CT and VT data.
Powerful reporting tool clearly documents the selection steps using flexible rich text format (RTF) that can be read by any word processing program.

Verify CT and VT data against device requirements, including protective and metering cores and VT windings. Support multiple protection schemes to help ensure accurate, reliable system protection and measurement performance.
Model CT transient performance, including saturation timing, and export COMTRADE files for deeper analysis and testing. Support IEC and ANSI CT classes and high-impedance protection schemes across diverse protection applications.
Automatically generate editable short and long RTF reports documenting selection results. Support Siemens SIPROTEC relays and many third-party devices to help streamline engineering validation and multi-vendor system integration.
