Description

This course will teach you single-line and three-line diagrams, their differences and graphic electrical components that figure on them. You will learn various elements that represent equipment like a circuit breaker, isolator, earth switch, power transformer, voltage and current transformer, lightning arrestor, auxiliary transformer, etc. You will also learn important switchgear parts like busbar system, mimic, control cubicle, cable compartment, local/remote control, interlocking (isolator/circuit breaker, isolator/earth switch, busbar isolator/busbar earth-switch), etc.

The course continues with explaining incoming and outgoing feeder philosophy and some switchgear theory like continuous and short-circuit rating of the equipment, ANSI codes, current transformer polarity, etc.

Finally, we will review the ACDB single-line diagram with interlocking, and 132/11kV single-bus and double-bus single-breaker scheme SLD, as well as relay and metering SLD.

The one-line diagram is most commonly used in power flow studies. Standardized schematic symbols are used to depict electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors. Only one conductor is displayed, rather than each of the three phases being represented by a distinct line or terminal.

When starting a new project or defining the scope of work, the single line diagram is the most critical document to consider and produce. In addition, a one-line diagram is necessary when preparing a shutdown/maintenance procedure statement.
