| Summary: | The electric power industry digital transformation
features and the intelligent electronic devices (IEDs)
introduction in the low-voltage circuits of power stations
and substations are considered. The analysis of normative
documents and standards is carried out. The features of
scheduled maintenance of relay protection and automation
devices are determined, the possibilities and prospects of
organizing condition-based maintenance are considered.
The mandatory steps required for any type of maintenance
are defined. A method for checking the electrical and
time characteristics of the overcurrent protection of an
intelligent electronic device is proposed. The device is
designed in accordance with the IEC-61850 standard and
operates in the local area network of a digital substation
of architecture III. |
