Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Power quality primarily encompasses short-duration events on the electrical system that cause equipment to misoperate or shutdown. The time delineation between a power quality event and a steady-state ...

Voltage fluctuations inside buildings are a common but often misunderstood problem. Lights flicker, appliances behave erratically, electronic devices reset unexpectedly, and motors sound strained.

In the upcoming NFPA 70E 2024 Edition, the inclusion of the phrase “at each point of work” and the relationship to absence of voltage testing has prompted questions regarding the use of Permanent ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) Determining if one voltage is greater than or less than another voltage is the job for a ...

Amplifier circuit offsets are always an important topic for any amplifier design. Most voltage amplifier circuit offsets are a result of the amplifier’s input voltage offset, input bias current and ...
