"Exactly what I wanted”
- Raymond Mitchell - Technical Planner - Philip Morris USA
“Explained with good examples and exercises.”
– Adam Ransick – Test Engineer – Rolls Royce
Purpose of Seminar:
In the field of equipment maintenance, installation or modification, the ability to read
and understand schematics and drawings is an absolute must. Several types of drawings and
diagrams will be examined during this course including Block, Pictorial, One-line, Wiring,
Terminal, and Schematic. The differences between these drawings will be emphasized and the
purpose and flow of each type will be clarified. In order to learn the symbolic language,
you must start at the beginning. In doing so, individual component symbols will be presented
along with an explanation of their function and purpose in the circuit. In order to make it
easier to relate the diagrams to the actual equipment, students will see pictorial examples
or photos of the components along with the description. Training will include exercises
where students create schematic diagrams based on circuit descriptions, as well as interpreting
schematic drawings so that they can provide verbal or written circuit descriptions.
Who should take this course?
This course is designed for anyone who needs to understand electrical drawings and schematics
for servicing and troubleshooting facility and industrial electrical systems. Attendees come
from a wide variety of industries, skill-levels, company sizes, and backgrounds, so if you're
not sure you'll fit in or will benefit from these classes, don't worry - you will - as long
as you work with electricity! People who will benefit from attending this seminar include…
