Abstract
Detailed field measurements of energy consumption (kWh) and demand (kW) are conducted on two injection molding machines (IMMs) used in a typical plastic manufacturing facility in the San Francisco Bay Area, with/without Variable Frequency Drives (VFDs) respectively. Significant energy and demand savings are verified for Injection Molding Machines (IMMs) retrofitted with VFDs. With the help of a digital oscilloscope, we made the power Quality measurements also. We will discuss the experience we have learned and the equipment requirements for this type of field measurement exercises.
