Frequently Asked Questions
WG 2 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 95/WG 2". This committee has published 792 standards.
WG 2 develops IEC standards in the area of Information technology. Currently, there are 792 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC TS 60255-216-1:2025 covers protection functions with digital inputs and outputs complying with IEC 61850 series and IEC 61869 series, in particular regarding
- subscription to sampled values (SV) streams representing energising inputs instead of analog inputs (see Figure 1);
- subscription to GOOSE (e.g. circuit breaker position, circuit breaker failure);
- publication of GOOSE messages (e.g. trip signals);
- subscription to time synchronisation messages.
On this basis, this document formulates requirements for protection functions with digital inputs and outputs and for the IED hosting them. The document also covers tests related to the functional interoperability and functional requirements of these protection functions, in addition to the general conformance tests required by IEC 61850-10:2012 and test related requirements in IEC TR 61850‑10-3:2022.
