ELECTRICAL PROTECTION


ELECTRICAL PROTECTION

INTRODUCTION: 

The Target Electrical Protection online training seminar 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 Target online training seminar will highlight: 

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

Course objectives: 

  • 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.
