The Safe Operation of High Voltage Power Systems (Full High Voltage Authorisation) to comply with HTM 06 – 03 (NHSHVAP)
NHSHVAP
This course provides an understanding of Hospital high and low voltage power systems including statutory regulations, safe operation, protection and fault diagnosis on a wide range of power equipment. It also enables candidates to perform HV switching operations on industrial HV networks up to and including 15kV, and prepares them for HV authorisation in accordance with HTM 06 – 03.

Who should attend?
Personnel who are to be responsible as authorised person for switching and issuing of electrical safety documents. Candidates with little HV experience may find it beneficial to attend our S9 course as a precursor to this course.
Certifications
Candidates who successfully complete the course and both theoretical and practical assessments will receive The Faraday Centre competence certificate. Candidates who fail will receive The Faraday Centre attendance certificate.
