Comprehensive solution for using distribution automation equipment in voltage quality monitoring

In consequence of technological development, more diversified functionality can be integrated into distribution automation equipment (e.g. remote readable energy meters, protection relays, etc.) installed at primary substations, secondary substations or at customers sites to provide potential for developing data analysis and management, e.g. for power quality monitoring. The main function of this equipment remains the original but the measurement data can be used also for power quality monitoring enabling also development of voltage quality evaluation functions.
