Duration:  3 days
Per Delegate:  £1,050.00

Practical Content


Theoretical Content


There are no prerequisites for this course.

Key Learning Outcomes

  • Gain an understanding of the basic principles in HV/LV switching.
  • Required knowledge of health and safety within a HV area and how to work safely.
  • Knowledge and skill to prepare and perform a switching and isolation within an HV/LV area.

Course Content

  • Safety regulations Health and Safety at Work etc Act 1974, The Electricity at work Regulations 1989
  • Electric shock effects
  • First aid procedures
  • Permit to work systems
  • Authorisation levels
  • Effects of faults on switchgear
  • HV/LV Protection Relays overview
  • Switchgear types and principles of operation
  • Generator operation
  • Control and capability diagrams
  • Synchronization
  • Load flow and load stability


Delegates will undertake an open book multiple-choice examination paper and practical assessment to demonstrate they have achieved the key learning outcomes detailed above.

PPE Requirements

Safety footwear, coveralls, safety glasses and gloves.

Further Information

Why ASET’s High Voltage Training differs from that of its competitors in Scotland:

  • ASET’s High Voltage equipment consists of a full range of HV and LV switchboards which can either be remotely switched through our Electric Control Panel or locally at the boards themselves.
  • The primary electrical supply comes from two of ASET’s Power Generator and VSD (Variable Synchronised Drives) which allows delegates the opportunity to synchronise and load share during training exercises
  • ASET has two fully rated Transformers which feed between HV to LV boards
  • ASET’s High Voltage technology and equipment is the most up-to-date consisting of Schneider fully rated Circuit Vacuum Breakers on the HV board and fully rated Air Circuit Breakers on our LV boards
  • ASET training personnel take delegates through extensive training and assessment on all HV and LV boards using live electrical power which is simulated for safety reasons to 6.6Kv. This also includes delegates creating suitable switching and isolations:

*ASET’s exclusive 0672 City & Guilds accredited programme has, over many years, become the entry course and standard in the North Sea and wider UKCS for further authorisations by Electrical personnel

*Part of the ASET competency assessment requires course delegates to complete a written examination and a practical assessment to demonstrate the knowledge they have gained throughout the course. This is mandatory for quality assurance and City & Guilds 0672 Certification.

Target Audience
Target Audience

Engineering personnel involved with power distribution networks, and the use of site operated switchgear, either onshore, offshore or onboard vessels.
