Lightning-caused faults on a utility power system can lead to voltage sags affecting customers over a wide area or high transient voltages resulting in
Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power
All utilities maintain statistics on the reliability of the electricity supply to consumers. In recent years, utilities have begun to track other power
For several years now, members of IEEE's P1547 working group have been developing a draft document to provide engineers with uniform guidelines pertaining
Power quality engineers can find an abundance of information about sizing and applying large UPS systems. When it comes to small, commodity UPS systems,
Power quality issues involve all aspects of power system operation, from steady-state voltage regulation to the control of high-frequency transients caused
As with many other aspects of the power industry, deregulation and restructuring are changing how utilities and customers approach power quality monitoring.
Damage from transient overvoltages is one of the leading causes of equipment failure. Although some pieces of equipment may come equipped with transient
When engineers need to evaluate harmonic concerns on power systems, they generally refer to Standard 519-1992 from the Institute of Electrical and Electronics
Considerable work is under way to establish indices that characterize voltage sag performance and benchmark system performance. Every two years, industry
Distributed generation (DG) is making a comeback. In the late 1970s, federal legislation sparked a flurry of interest in the topic. Today it is once again
Abstract: In this webinar, Mike will not only explain the current NEC requirements for GFCIs and AFCIs, but he'll explain how they operate, what causes their premature failure, and when they won't provide the safety protection you might have thought they would.
Abstract: This webinar will teach attendees the difference between risk and hazard, and how the choice of system grounding has a direct impact on reliability and safety.
