    Lightning continues to be the major cause of outages on overhead power distribution lines. Through laboratory testing and field observations and measurements, the properties of a lightning stroke and its effects on electrical distribution system components are fairly well-understood phenomena. A meticulous compilation of 32 years of historical records has been kept for outage causes, duration, and... View full abstract»

    Currently, the calibration of photometers is based on the spectral sensitivity of the eye with the field of view limited to only 2 degrees. However, lighting applications of interest in work environments are rarely confined to such small fractions of the visual field. New research shows that the eye spectral sensitivity is different when a full field of view is considered. The changes in spectral ... View full abstract»

    Application of overcurrent protective devices for generators and transformers is considered to be a routine task. However, a review of the protective device selection, device settings, and protection requirements for generators and transformers, as well as their connected buses, has revealed that certain lessons can be learned in examining a few typical applications. The applications are presented... View full abstract»

    The phenomenon of transformer magnetizing inrush current has been discussed in many papers throughout the years. A brief review of magnetizing inrush is given to provide the basis of need for transient testing. Previous studies have shown that inrush currents contain harmonic components of the fundamental waveform. Conventional philosophy has been to utilize the second harmonic current to provide ...

    Large industrial operations with internal electrical generation capabilities and parallel utility ties have always worked to control watt and VAr flows across their tie lines. In today's economic climate, the ability to control tie line operation can significantly impact a facility's bottom line. In a power system expansion, Union Camp Corporation's Savannah pulp and paper mill installed a tie lin... View full abstract»

    Dynamic Modeling Technology (DMT) is a new approach for modeling process transfer functions, which reduces the effort required to obtain accurate process models. DMT is able to automatically determine the structure of the transfer function model as well as the values of the model parameters using an unstructured approach based on orthonormal Laguerre functions. DMT provides several advantages comp... View full abstract»
