Flexible Electronic Fiber-Optic Current Transformers
Flexible Electronic Fiber-Optic Current Transformers (F-EFOCT) are an alternative to Conventional Current Transformers with inductive transducers for high-precision current measurement and power quality control, in medium and high voltage systems. These innovative current transformers provide digital output according to the IEC 61850 standard for your metering and protection infrastructure. The F-EFOCT excels with a very high stability over a large temperature range, optimal performances over an increased frequency bandwidth, as well as a wide dynamic range and good performance under transient operations.
Applications for EFOCT:
CONDIS® Instrument Transformer product range is ideal for your transition to digital substation technology. CONDIS® F-EFOCTs can be configured for the use in revenue metering, measurement of electric power quality parameters and relay protection & automation alike. Due to its adaptable current sensing head, the F-EFOCT can easily be installed at existing infrastructure such as cable terminations or generator busbars.
