Electronic fiber-optical current transformer (EFOCT)
Electronic Fiber-Optic Current Transformers (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 metering and protection infrastructure. The 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. Profotech instrument transformer product range is ideal for your transition to digital substation technology.
