    In the wake of deregulation of the utility industry, electric utilities have to equip themselves with the appropriate tools and personnel to perform various studies of the distribution and transmission lines, which aid in foreseeing an outage or a failure before it occurs. Such preventive measures amount to an efficient way to market power, retain the demand and flourish in this business. Voltage ... View full abstract»

    Recently, a line has emerged: on one side computer applications working productively for electric utilities; and on the other side computer applications posing a burden for the utility. Setting clear objectives and research will assure a utility of being on the productive side of the line. Computer systems that work well for one utility may not work well for another. Electric utilities are differe... View full abstract»

    In evaluating alternatives in the design of transmission facilities, first cost alone is not always the true cost of the project. Using the present-worth method to determine the cost of the project over the life of the facilities represents the total cost of constructing and maintaining the facilities. Present-worth analysis was also used in determing whether it was more economical to completely r... View full abstract»

    This paper presents a harmonic study on a newly developed solid-state fault current limiter. Using this device, the supply voltage sag is reduced when a short-circuit fault occurs on a cable feeder in the downstream network, hence improving the power quality. The device will eventually isolate the faulted part from the healthy network. Harmonics caused by the fault current limiter are analysed and... View full abstract»

    Flywheel energy is stored in the high inertia rotor of a special Written-Pole(R) motor. This Power-Ride(R) motor is made inside-out, with the outside rotor spinning around the wound stator that is inside. Using this motor to drive a water pump causes slow rates of acceleration and deceleration. This leads to slow changes in flow rates of the water being pumped. Water hammer i... View full abstract»

    There are numerous factors that must be considered when upgrading the current carrying capacity of an existing transmission or distribution line. The selection of the replacement conductor may not be as straightforward and simple as changing to a larger conductor size. A more viable solution may be to evaluate the ACSS conductor design. This paper provides a brief explanation of what the ACSS (alu... View full abstract»
