Why Choose this Training Course?

Operational safety of all electrical installations is crucial, any compromise with safety, quality and design will have catastrophic effects on the assets, personnel, and operations. The consequences of an incident involving high voltage electricity are usually more significant than for low voltage. They include severe injury or death from electric shock which may be received by direct or indirect contact, tracking through or across a medium, or by arcing burns from arcing, explosion, or fire. The first line of defense when an abnormal situation arises and to isolate the faulty circuit safely are the circuit breakers and protection relays.

An effective earthing or grounding system is vital as it constitutes the integrity of the electrical installation. Earthing systems help to reduce step and touch voltages as well as Earth Potential Rise (EPR) at the defective high voltage structure when there is a fault or equipment malfunction at the substation. This will arrest leakage currents and improve power quality issues. The implementation of energy isolation technique includes the proven OSHA lock out tag out method. An electrical installation is deemed to be safe with the inclusive of aggressive maintenance culture. A way forward is the conditioned based maintenance with sophisticated testing and measuring instruments.

This PetroKnowledge training course will highlight:

  • Arc flash incidents including the importance of safety, risks and hazards of electricity
  • Eco efficient high voltage circuit breakers
  • Types of earthing network and its merits
  • Energy isolation techniques including LOTO
  • Implementation of an effective maintenance programme
