Course Overview

This course covers the theoretical and practical principles of pressure testing on high voltage distribution systems up to and including 15kV. It covers the different insulating material characteristics as well as the methods used to enable the pressure testing of high voltage equipment, including cables, switchgear, transformers and motors. The course strongly emphasises safety requirements and interpretation of test results.

Who should attend?

Electrical Engineers/Technicians responsible for carrying out or supervising high voltage pressure testing. It is recommended that candidates should be authorised to receive sanction for test documents before taking this course (see S8 course).


Candidates who successfully complete the course and both theoretical and practical assessments will receive a Faraday Centre competence certificate. Candidates who fail or do not wish to undertake the competence assessments will receive a Faraday Centre attendance certificate.
