Those who attend the Schematic Electrical Print Reading course will be led through this fast-paced three day course by a current field trainer and former substation technician. Robert brings 36 years of experience in the electrical field. He is eager to share his experiences in using electrical prints for maintenance, troubleshooting, relaying, metering, equipment commissioning, and, most importantly, safety while switching.

Topics covered include:

  • Electrical print terminology. 1 line, 3 line, ladder, schematic, power scheme, control scheme, and more
  • Symbols, devices numbers, and abbreviations: what do they mean? How do they work with each other?
  • Switching – Your print is the road map. Can you read the signs?
  • Control schematics – AC/DC, basic theory, applications, voltages, troubleshooting tips.
  • Power circuit breaker – physical layout, CT and bushing numbering, and control scheme
  • Basic relay schematics – How does the print apply to testing, commissioning, and troubleshooting?
  • Logic diagrams – AND, OR, NOT, series, parallel, How are they related?
  • Safety in troubleshooting – Multi-meter use, shorts, opens, grounds, and line of fire

You will learn:

  • The principles of reading electrical prints
  • How to identify different types of electrical prints
  • How to identify symbols and device numbers
  • How to draw basic 1 line, ladder, and panel wiring prints
  • How to use electrical prints for troubleshooting and testing
  • How to use electrical prints for safe switching procedures
  • Why electrical prints are important whether you are a substation tech, a telecom tech, a lineman, etc

Pre-requisites for this course include previous experience in the electrical field, a working knowledge of D.C. and A.C. theory with practical experience in circuit analysis and troubleshooting will be helpful, and knowledge of IEEE Device numbers will also be helpful but not necessary.
