DESCRIPTION

Electrical insulation is designed to isolate conductors in an electric circuit and to protect personnel. Motors, cables, and other electrical components employ complex insulation systems that can be easily undermined by moisture and heat. Testing and determining the quality of electrical insulation requires knowledge of megommeter and high potential testing.

WHO SHOULD ATTEND

  • Engineering and design personnel
  • Maintenance and technical services personnel
  • Process and operations personnel
  • Technical and process managers
  • Engineering and design personnel
  • Electrical consulting engineers
  • Electrical contractors
