Switchgear Assessment Panel (SAP)
The safety and reliability of electrical equipment used by the electricity industry is paramount in enabling the industry to discharge its legal and license obligations and its duties to its employees, its customers and, its shareholders. The equipment used by the industry must conform not only to relevant standards but also meet electricity industry requirements.
The ENA co-operates with manufacturers in assessing new products and, if necessary, in witnessing tests. Products that meet the specified criteria are given an ENA Notice of Conformity Certificate through the appropriate Assessment Panel. Participation in these arrangements is voluntary and the fact that a product is not has not been assessed does not preclude its purchase by the industry.
For details of Assessed Switchgear see the Assessed Equipment List - Switchgear (ALS) ALS 2/10 Jul 2017
Assessments are managed by the: Switchgear Assessment Panel (SAP) and undertaken by nominated groups of expert switchgear Specialists
The panels are made up of representatives from the Distribution and Transmission Network Operators.
A major criterion for acceptance of a product for assessment is the interest and support of ENA Member Companies, applicants should have the support of two members of the appropriate panel.
All products accepted for assessment must meet the requirements of the relevant ENA Technical Specifications.
The assessment process is detailed in ENA Technical Recomendation G79 part 1 and it's associated level 2 documents, (Part 2a - Switchgear).These are available from the ENA Document Catalogue.
Assessment may encompass up to four areas:
Quality of manufacture (if appropriate)
Type tests to relevant standards
Performance or functional tests to agreed criteria
Site tests or trials
