Course Description

Poor grounding practice can be the cause of continual and intermittent difficult-to-diagnose problems in a facility. The aim of this course is to increase awareness of and importance of correct earthing practices to ensure safety of personnel plant and equipment and at the same time to understand the codes that govern the designs and installations.

Course Objectives

  • Identifying safety hazards created by ineffective grounding systems
  • Understandig the effect of connecting grounded and bonded systems
  • Being familiar with  the different earthing systems, principal design considerations and methods of lightning protection systems
  • Understanding how to protect personnel, plant and equipment during an earth fault or lightning strike
  • Being familiar with the requirments to design, install, test, and maintain correct earthing and lightning protection systems

Who Should Attend?

  • Building service designers
  • Design engineers
  • Field technicians
  • Electricians
  • Plant engineers
  • Power system protection and control engineers
  • Project engineers
