Prerequisites

  • The basic electrical principles
  • A basic understanding of electrical engineering

Description

Protection & control systems are a critical part of the transmission & distribution systems that feed power to megacities & industries.

This course aims to introduce all of the basic principles associated with electrical power systems protection with examples.

I have tried my best to include a practical example from the field as I have 17 years of field experience in substations. I have included real examples, equipment nameplate, Single line diagram, real field examples.

The course will go into detail for the following key topics: –

Introduce all of the key concepts of a protection system, power quality, reliability, fault & event recording.

Show the basic principles behind electrical protection philosophy

Explained cascade tripping, Comtrade files, how to localize the faults

Look at step & touch potential concept, Voltage or Current which is lethal

Why gravel is used in substation, How to protect equipment & human

Look at Earth Leakage Relay, How it operates

Understand protection philosophy, A) Selectivity. B) Sensitivity. C) Speed. D) Reliability. E) Simplicity. D) Economy.

· Relationship between selectivity and zones of protection. open & close zones, tele protection

Look at Primary, backup & duplicate protection

Look at relay classification, Electromechanical, Digital, Microprocessor & Numerical relays

What are phase & ration compensation in transformer differential protection, interposing C.Ts

How Over Current, Earth fault relay operates

· How Direction Overcurrent relay, Definite time & reverse time overcurrent relay operates.

Understand Magnitude, differential & phase comparison principles

Look at the working principle of Breaker failure relay

Look at the basic electrical theory, Ohms Law, KVL, KCL, Calculate HV & LV rated & short circuit current transformer

Introduction to the per-unit system, how to evaluate arc flash hazard using the per-unit system

Look at three-phase systems, balanced, unbalanced, three-phase fault, phase to phase fault, phase to ground fault

Understand Symmetrical components

Look at primary & secondary equipment, electrical wiring basics

Understand Auxiliary relays, Main relays, Contactors

Difference between Circuit Breaker & Isolator & Load Break Switch

Understand the concept of interlocking

Understand surge arrestor & surge counter

Look at GIS, AIF & MV SWGR

· Look at CB operating cycle, pole discrepancy, anti pumping, trip circuit supervision schemes.

Intro to ANSI device codes

Introduction to internal, external & through faults

Look at Capacitor Storage trip units

Show batteries & charger, how they work, Single Line Diagram of DC system, Single Line Diagram of Charger

Look at LCC, Gas diagram, Gas compartment, Gas permeable & Gas tight

Introduction to Relay Coordination

Look at complete protection engineering cycle Design Phase, Manufacturing Phase, Shipment Phase, Inspection, T&C, Maintenance

Look at three-phase currents and see how they can be broken down into sequence components and harmonics.

Provide the basic principles behind current transformers, how they operate and need to be connected

Show how voltage transformers operate and introduce the key types

Go into detail on what happens when a fault occurs on the system

Look into circuit breaker control and protection systems and how they interact with the protection systems.

The main protection relay we will look at on this course is over protection. We go into detail on the basic and more advanced versions and show how this relay can be put to good use to provide great fault discrimination

Look at the different types of earth fault relays and see how they can be used to protect some key equipment \ s

By the end of the course, the student will be able to identify all of the key components of a protection & control system, understand how all of these components fit together to create a fully integrated system, protection fundamental concept, protection schemes & relays, battery charger & batteries.

Remember that Udemy offers a 30-day money-back guarantee. I am also always available for questions while you go through the course to ensure everything is clear.

See you in the course!
