An Intensive 5-Day Online Training Course

Electrical Protection

Characteristics, Types and Functionalities of Protection Relays

We currently have no scheduled session for this Course. If you are interested in running this course, please contact our Training Department at

Why Choose this Training Course?

The Electrical Protection online training course will look into the fundamental and critical aspects of electrical installations. Protection is applied on a component basis. Relays are associated with each significant component of the power distribution system to detect various forms of distress associated with those components. If one of those relays operates, which means that an output contact protective devices, which then isolates the defective system components. It may be convenient to think of the circuit breaker as the muscle that does the work of isolating the component, while the relay is the brain, which decides that isolation is required.

This Electrical Protection online training course will highlight:

  • Operational Principles and Types of Electrical Protection
  • Design of Different Types or Relays
  • Protection Coordination and Architecture
  • Protection for Feeders, Motors and Transformers
  • Short Circuit Current Calculations

What are the Goals?

At the end of this Electrical Protection online training course, you will learn to:

  • Appreciate the practical solutions for specifying the correct type of electrical protection
  • Understand comprehensive understanding of principles and selection of relays
  • Develop design of protection schemes
  • Learn the construction and functions of instrument transformers
  • Explain types grounding system and earthing fault protection

Who is this Training Course for?

Electrical protection is a very important component in all electrical installations. It is imperative that all personnel associated with electrical installation operations and maintenance need to understand the concepts of electrical protection.

This Electrical Protection online training course is suitable to a wide range of professionals but will greatly benefit:

  • Engineers and Technicians from the Electricity Supply Industry
  • Technical Management Professionals and Department Leaders
  • Engineering Professionals from companies manufacturing and operating power and distribution transformers
  • Engineers and Technical Personnel in power utilities, petrochemical plants, service professionals of large infrastructure projects
  • Maintenance and Operations Technicians

How will this Training Course be Presented?

This PetroKnowledge online training course will utilize a variety of proven online learning techniques to ensure maximum understanding, comprehension, retention of the information presented. The training course is conducted online via an Advanced Virtual Learning Platform in the comfort of your choice location

Organisational Impact

This Electrical Protection online training course provides an ideal way to cater to the technical training of personnel. The benefits for the organisation can be summarised as follows:

  • Technical training and up-skilling to improve and realise the full potential of a competent workforce
  • Productivity increase through minimisation of project time acceptance/design and commissioning
  • Identification for opportunities of improvements due to deep understanding of the presented state-of-the-art technologies
  • Networking of personnel with technology leaders and other engineers and technicians with strong field experience
  • Exposure of personnel to the standard international procedures
  • Attitude change of workforce, as continuous follow up of new technologies, and they're up to taking could otherwise create a workforce with high resistance to change due to lack of understanding

Personal Impact
