Data transmission from electronic current transducers to a process bus in the IEC 61850 standard
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2015, Vol 524, Issue 4
Abstract
The IEC 61850 standard is used more and more commonly now in the implementation of new distribution stations or modernization of the existing ones. One of the major aspects in proper functioning of such systems is the measurement of basic electric quantities, such as current and voltage. The article features the description of a system for acquisition and transmission of instantaneous values of current with the use of coreless transformers. The major implementation issues of the system were presented, along with factors which may impact further improvement of the system technical parameters.
