Reduced voltage starting is a technique that has gained recognition among industry experts for its potential to reduce current demand. It might seem complex for new consumers, but let’s simplify it and explore its benefits, the science behind it, and its applicability.
Understanding Reduced Voltage Starting
There are several methods for reduced voltage starting, all with the same objective: to conserve energy and decrease peak demand on a system. In the context of rotary screw compressors, this is usually achieved by starting the motor wired in a WYE connection, where phase loads are connected at a single, neutral point, and then switching to a Delta Run connection. In simpler terms, this allows a tool to gradually apply voltage and control the electrical load of a startup, instead of instantly bringing it to full power. This system can prevent brownouts and severe voltage drops when a motor is started, especially in areas where utility power is limited or heavily burdened.
Identifying the Right Tool
This feature is standard on all “E” series machines listed on the Compressor World website and several other rotary screw air compressors. Remember, when buying any electrical machine assembled for use in the United States, the entire electrical system must be UL approved, not just the components. If a tool is approved, you should expect to see a “UL” sticker on the electrical cabinet door.
Conclusion
Reduced voltage starting is a valuable technique for conserving energy and reducing peak demand on a system. By understanding how it works and identifying the right tools, you can leverage this method to optimize your operations.
