Basic Electrical Theory

January 23 & 24 2017

After Participating in this course, you will be able to:

  • Understand the physics of electricity: current, voltage and power
  • Calculate electrical power
  • Manipulate series and parallel circuits
  • Understand and work with electrical fields (capacitors and inductors)
  • Understand AC vs DC


In this webinar, conductors and insulators are investigated, along with their connected components, capacitors and inductors. You will be introduced to the first and most important topic, Ohm’s Law, the relationship between current, voltage and impedance, and its relevance to series and parallel circuits.
Subsequently, this will lead to Kirchhoff's Laws to further analyze network analysis and complex electrical circuits. Using complex numbers, reactance and impedance will be investigated as they relate to AC circuits.

Course Outline:

  • What is electricity; current, voltage and power
  • Electrical fields & electromagnetism
  • Electrical power
  • Series and parallel circuits
  • Kirchhoff's current & voltage laws
  • Theorems (Superposition, Thevenin, Norton)
  • Capacitors and inductors
  • Alternating Current
  • Vectors & phasors
  • How capacitors and inductors work with AC

Basic Digital - Electric Circuits

January 25, 2017

After Participating in this course, you will be able to:

  • Work with binary arithmetic
  • Understand the functionality of logic gates and switches
  • Use electromechanical relays to form gates
  • Understand the functionality of sequential circuits and shift registers
  • Comprehend analog to digital conversion


This webinar will begin with binary numbering systems and binary arithmetic. From there, logic gates and switches will form the basis of further study in Combinational Logic Functions. Electromechanical relays will demonstrate logical functions and will then lead to more complex circuitry of sequential circuits, shift registers and solid state components. Analog to Digital Conversion (ADC) will also be looked at along with digital storage (memory).

Course Outline:

  • Numbering systems
  • Binary arithmetic
  • Logic gates
  • Electromechanical relays as gates
  • Combinational logic functions
  • Sequential circuits & shift registers
  • Analog to digital converter
  • Digital storage

Basic Protection & Control

January 26 & 27 2017

After Participating in this course, you will be able to:

  • Comprehend the purpose, requirements and elements of protective relaying
  • Identify the various protection schemes
  • Use standard relaying terminology
  • Recognize the various types of circuit breakers
  • Understand the various relay schemes and the types of relays used


Starting with fundamental relaying terminology, the purpose, requirements and elements of protective relaying will be examined along with the simplest of protection schemes, including surge protectors, fuses and reclosers.

Gain an introduction to the various types of circuit breakers (including open and close controls) and instantaneous and timed overcurrent protection. Study differential protection, pilot wire protection and impedance relaying, and review examples of yesterday’s electromechanical relays and today’s more modern IED relays. Permissive overreach, directional comparison protection, and transfer tripping and remote tripping will also be covered.

Course Outline:

  • Protective relaying
  • Relaying terminology
  • Fuses & fuse coordination
  • Reclosers & sectionalizers
  • Circuit breakers
  • Various relay protection schemes
  • The Westinghouse KD relay
  • The GE L90 (Multilin™) Line Current Differential System
  • L.V. Feeder Protection
