Education Session: Low- and Medium-Voltage Electrical Systems

In this session on Oct. 19, 2021, you will learn about the codes and standards regarding electrical system design, understand the basics of a single-line diagram, explore products and systems within the low- and medium-voltage classification, and review buildings in which both low- and medium-voltage electrical systems have been included, and their interaction.

There are several reasons to choose one voltage level over another for electrical transmission. First, the requirements of the electrical system must be defined. Voltage is determined by the equipment requiring power. Another reason is the cost. With higher voltage comes less copper for wiring, but more money for electrical equipment.

Low-voltage systems typically serve lighting, fire/life safety systems, receptacles, communication systems and small equipment. Medium-voltage systems serve many different needs in commercial buildings. ANSI C84.1 defines medium voltage as being “a class of nominal system voltages greater than 1,000 volts and less than 100 kilovolts.”

Once the requirements for electrical transmission have been determined, the electrical engineer must design a system that is both safe and effective for the commercial building. Learn more at this Low- and Medium-Voltage Electrical Systems session on Oct. 19, 2021.

The presenters for this Fall 2021 Virtual Training Week course are: Kenneth Kutsmeda, PE, LEED AP, engineering manager, Jacobs, Philadelphia, and Jane Baikadanova, PE, associate principal/senior electrical engineer, Page, Washington, D.C.

Registration is free for all coursework. Complete information about Fall 2021 Virtual Training Week is available online.
