Laboratory testing of process bus equipment and protection functions in accordance with IEC 61850 standard. Part I: Electrical arrangement and basic protection functions tests

The use of process bus modern technology in accordance with the IEC 61850 protocol allows performing modern measurement and improving the protection automation system. It also allows for the integration and complex building of functional automation and control systems based on network devices in Ethernet technology. The paper presents measuring tests of a process bus equipment and the operation of protection functions based on measurements.
