IEC 61850-3:2013

Communication networks and systems for power utility automation - Part 3: General requirements

IEC 61850-3:2013 defines the general requirements, mainly regarding construction, design and environmental conditions for utility communication and automation IEDs (intelligent electronic devices) and systems in power plant and substation environments. These general requirements are in line with requirements for IEDs used in similar environments, for example measuring relays and protection equipment. This new edition includes the following significant technical changes with respect to the previous edition:
- requirements are in line with those of other equipment used in the same environment (e.g. protection relays);
- product safety added based on IEC 60255-27;
- EMC requirements completed and in line with IEC 60255 series and IEC 61000-6-5.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
