Four steps on energy

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...

Thinking inside the box: Energy costs drive ac-drive innovations

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.

Basics of power management software

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.

Basics of power management equipment

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.

A physical analogy for ac electrical power

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.
