What does power management mean?
Reliable energy efficiency policies are being given a new lease on life by the introduction of better technology solutions.
Differing IEC, ANSI requirements can impact compliance.
Although offline or static testing is an important part of a routine maintenance program, dynamic testing of motors can be done more frequently and, in many cases, with greater benefit.
Variable frequency drives (VFDs) are designed to reduce energy usage by controlling the speed of the motor and can offer cost-effective benefits for plants.
ANSI/EASA AR100 provides best practices for mechanical repair, electrical repair including rewinding, and testing that help apparatus rebuilders maintain or enhance the performance, reliability, and energy efficiency of ac and dc motors and generators.
Industrial buildings are responsible for 31% of global energy consumption, easily exceeding all other building types. While industrial facility ownership and management have generally been cognizant of energy as it relates to cost control and the competitive advantages of being viewed as green and sustainable, that statistic suggests that many energy efficiency opportunities aren't being exploi...
The types of ac drives used with ac induction motors are V/Hz, encoderless and flux vector. While there are many drives available for synchronous and servo motors, induction motors have the majority of applications. Sensorless vector control is the same as encoderless vector control, which better describes its operation.
Powerful analytical tools — software, PCs, networks, and the internet — are within a click of the mouse. Power monitoring equipment captures data; software analyzes critical data required for responsible electrical energy management. Power management software tools provide control over how you manage your use of electricity.
Electrical power enters the plant, drives the equipment, shines the lights, conditions the air, makes the coffee, and runs the printer that prepares your paycheck — and the check to pay for all this electricity. Are you getting your money's worth? Probably not.
Electricity cannot be seen physically; only its effects can be seen or felt. At times, some aspects of electricity can be difficult to understand. One such phenomenon is the presence of different types of power in ac electrical systems. This article presents a physical analogy of electrical power as a refresher to help you understand these concepts further.
