SC D1 Mission and Scope

SC D1 Materials and Emerging Test Techniques, Mission and Scope

MISSION

• To facilitate and promote the progress of engineering and the international exchange of

information and knowledge in the field of materials test technologies and diagnostic tools for

electric power systemselectric power systems

• To improve the information and knowledge by synthesising state-of-the-art practices and

developing recommendations and to identify, investigates, monitor and report upon new or developing recommendations and to identify, investigates, monitor and report upon new or

novel materials, emerging technologies and diagnosis test techniques which have the

potential for application within electric power systems but where the precise nature of such

use is unclear or where technological obscures a clear route to implementation

SC D1 Mission and Scope (cont.)

MISSION (cont.)

• To make recommendations to relevant study committees for activity regarding new or novel

materials, emerging test technologies and diagnosis techniques and concepts which have

reached, or are about to reach, a level of maturity where experimental developments or

prototypes can be applied to electrical power systems or where a clear route to

implementation can be foreseenimplementation can be foreseen

• To investigate, monitor and report upon the use of new or novel materials, test technologies

and diagnosis concepts that are sufficiently mature for use within electric power systems but g p y p y

which can be commonly applied across several study committee areas

• To support other study committees in their analysis of recently introduced and developing

materials, tests techniques and concepts where relevant expertise exists within D1

SCOPE

The activities of CIGRE Study Committee D1 concern the following main

directions:

• new and existing materials for electrotechnology,

• emerging test technologies and diagnosis techniques,

• support of other study committees in their analysis of recently

introduced and developing materials, emerging test technologies and

i i idiagnosis techniques

Said activities are focused mainly on transmission and distribution but emerging

generation technologies will also be specifically consideredgeneration technologies will also be specifically considered.

5


SCOPE (Cont.)

Within this scope, the work of the Study Committee is principally scientific in

nature and has as its main aim the provision of timely information on new developments and

trends in the field of materials and emerging test technologies to other CIGRE Study

C itt Committees.

Through its work the Study Committee strives to keep CIGRE fully aware of the

evolution of materials and emerging testing technologies relevant to its activitiesevolution of materials and emerging testing technologies relevant to its activities.

Where the scope of SC D1 work overlaps that of other study committees, we will

strive for good communication and co-operation, the co-ordination of all activities, and, strive for good communication and co operation, the co ordination of all activities, and,

where appropriate, joint activities. Such interactions will extend to all study committees.

Strategic Plan of SC D1

Major changes to previous plan

• Scope of SC D1 extended to all kind of materials for electrotechnology,

i.e. electrical insulating and electrical conducting materials (already

effective since 2008)

• Scope of SC D1 to be extended to electrical insulation systems (EIS)

[Electrical insulation system (EIS): Insulating structure containing one or more electrical

insulating materials (EIMs) together with associated conducting parts employed in an

electrotechnical device (IEC 60085)]
