Load alternator relays

The video tutorial explains the importance of using duplicate mechanical plant items like pumps, fans, and compressors in various infrastructures to ensure reliability and load matching. It covers the use of alternating relays for controlling these systems, ensuring equal wear and operational efficiency. The tutorial also delves into the operation of alternating relay circuits for compressors and fan control using solenoids and switches. Additionally, it discusses the role of lead and lag sensors in managing air compressors to meet varying demand levels.
