It was in the area of the US Navy's Extremely Low Frequency (ELF) antenna where the distribution system had been recently reconfigured so that the transformers were connected line-to-line in order to eliminate interference from the antenna. A study was done which determined that the system was susceptible to ferroresonance during single line faults under highly loaded conditions and that the overvoltages experienced could be causing the lightning arrester failures. This conclusion was further strengthened by a statistical study which compared the actual number of failures to an expected number of failures given the system's loading condition and fault rate.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

Since this is becoming a widespread problem today, and new, more strict, distortion guidelines are under development, utility engineers are having to deal with analyzing and planning for the control of the distortion. The authors introduce some common harmonic analysis techniques and apply them to voltage waveforms recorded on a typical REA transmission and distribution system.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

The forces that drive the development are highlighted. Then a description is given of the current status and trend for DA, indicating how some of the DA functions are related to DSM. The author shows how the use of computer and communications technologies facilitates the integration of DA and DSM, and illustrates this integration by some utility examples. The major conclusion is that DA and, DSM should be jointly considered in utility strategic planning.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

Not only does the process destroy all PCBs, but it also yields recyclable metals. An askarel transformer (or one with level of PCB contamination) arrives at the facility, where it is drained (if the unit arrives full) and off-loaded. The internals of the transformer are then solvent washed to remove gross amounts of PCBs. After the component parts are disassembled (i.e. core, coils, tank), they are solvent cleaned to <10 mu g PCB/100 cm/sup 2/. The solvent is distilled to <2 p.p.m. for reuse. The wood, paper, and still bottoms are sent out for incineration. The aluminum is smelted, the steel is prepared at the facility and shipped directly to a smelter, thus bypassing scrap yards and their inherent PCB problems, and the copper is prepared and sold on the commodities market. The PCB transformer owner receives a Certificate of Destruction certifying that all the owner's PCBs have been destroyed.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

The major emphasis is on substation applications, although distribution system applications are also discussed. The developmental background, measurement techniques, control features, and several specific applications of the control relay are described. The control relay responds to the actual measured power factor with voltage override and load current-following capability, which allows it to respond differently during light and heavy load conditions. The control has optional time-of-day and day-of-week voltage biasing capability. Use of additional control inputs such as a temperature override function to allow the switching of capacitor banks in anticipation of weather related load is also described.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.

Coverage is also provided of the following studies required for interconnection of the induction generators with the public electric utility: load flow, short circuit, stability, protective relaying requirements and protective device coordination studies. It is shown that the induction generator does not require a separate DC excitation system and synchronizing is not required. Because of its simple rugged construction, the induction generator is inherently a low maintenance machine compared to the synchronous machine and has higher expected reliability.<<ETX>>","PeriodicalId":398621,"journal":{"name":"[Proceedings] 1991 Rural Electric Power Conference.
