  • Chaotic Population Dynamics and the Evolution of Aging

    According to accepted evolutionary theories, aging has evolved as a side- effect of strong selection pressure for early fertility, despite the fact that it has no adaptive value of its own. I have argued elsewhere that recent experimental results make these theories untenable, and that there is now a broad array of evidence indicating that aging has evolved as an adaptation, selected for its own sake. To explain nature's preference for aging is a substantial theoretical challenge. The classical Weismann hypothesis, "making room for the young," faits because the benefit to the population accrues in the form of enhancement to the rate of increase of population average fitness, while the cost affects individual fitness directly and efficiently. In multi- level selection models, the aging genes are lost before their benefit can accumulate. I propose here that aging has evolved based on a different benefit: its contribution to demographic homeostasis. I argue that population dynamics are inherently chaotic, and that the stable ecosystems that we commonly observe in nature are a highly evolved phenomenon. Natural selection for population homeostasis is far more efficient than selection for rate of evolution because chaotic population dynamics can be lethal on a time scale of just a few generations, while enhanced rate of evolution takes far longer to affect population mean fitness. My thesis is that aging can evolve based on its ability to damp population fluctuations. For illustration, I offer an individual-based computational model that reproduces chaotic population dynamics with a delayed-feedback logistic equation. Genes for aging emerge handily.

  • Thermal Aging of ThickFilm Resistors

    The paper reports the results of a systematic study of the effects of thermal ageing in thick-film resistors (TFRs) over a wide temperature range (from 125¿¿C to 4O0¿¿C). The relative change of resistance ?>R/R was studied as a function of ageing temperatures and times. TCR and excess noise index before and after ageing processes were also measured. These electrical properties were investigated on samples prepared in the same way, except for the substrate, the latter being in all cases 96% alumina, taken from five different suppliers. A systematic difference in ?>R/ R for the same ageing conditions is observed in samples on different substrates. The relative change of resistance is positive after ageing at lower temperatures up to very long times; it follows a square-root dependence and is thermally activated. At higher temperatures ?>R/R is negative and follows a linear time dependence. Resistors with different thicknesses were also analysed; the thinner the sample, the larger is the ?>R/R observed under the same ageing conditions. All these experimental findings must be considered in a comprehensive interpretative scheme of ageing mechanisms of TFRs on alumina substrates.

  • Evaluating Insulation Materials and Systems

    This chapter describes the practical aspects and limitations of accelerated aging tests used to determine the capability of winding insulation systems. There are many different stresses that can affect the rate of insulation deterioration in stator and rotor windings. The chapter describes thermal, electrical, ambient, and mechanical stresses, the so-called TEAM stresses. Each insulating material has its characteristic breakdown strength. Elaborate methods have been developed for measuring the short-term (voltage is applied for less than a few minutes) breakdown strength of insulation. The notion that some failure processes in rotor and stator windings do not occur as a result of a single stress or factor but, in fact, depend on two or more stresses/factors. Thus, to reasonably duplicate some failure processes in an accelerated aging test, more than one stress needs to be applied at the same time.

  • Core Lamination Insulation Failure and Repair

    This chapter discusses the most common causes of stator and rotor core failures in both induction and synchronous machines, together with proven repair methods. Degradation of the core condition due to the effects of thermal aging can occur in all rotating machine laminated cores. Electrical aging occurs when the voltage across the lamination insulation induced by magnetic fluxes, electromagnetic forces, or high ground-fault currents causes deterioration. The most common causes of mechanical degradation in cores are inadequate core pressure applied in manufacture, core pressure reduction in service due to relaxation of the core support structure, core vibration, back- of-core looseness, and mechanical damage causing smearing of the core surface at the bore. A number of different core insulation defects can be introduced during manufacture and these may not be detected if adequate quality assurance (QA) checks are not performed.

  • Salient Pole Rotor Winding Failure Mechanisms and Repair

    Modern salient pole winding designs use aramid paper ground and turn insulation in strip-on-edge windings, resin-bonded glass laminate pole washers DacronTM and glass-covered high-temperature enamel turn insulation in wire wound poles, and thermosetting bonding resins. Insulation aging from thermal cycling occurs mainly in synchronous motors and generators that are started and stopped frequently. Salient pole rotor windings, especially strip-on-edge types, are generally susceptible to failure from contamination by conducting materials because they rely on adequate creepage distances between bare copper conductors to prevent shorts. Abrasive dust from the surrounding atmosphere carried into the interior of a motor or generator by cooling air will abrade the rotor winding insulation surfaces. Among the most common causes of failure in salient pole rotor windings are the continuous centrifugal forces imposed on them by rotation and the cyclic centrifugal forces induced by starting and stopping.

  • Round Rotor Winding Failure Mechanisms and Repair

    This chapter describes the aging processes and failure mechanisms affecting rotor winding insulation and, where appropriate, the winding conductors of round rotors in turbine generators and high speed synchronous motors. The repairs covered in it tend to be common for all types of deterioration processes. Thermal degradation of these materials may be treated as a chemical rate phenomenon and includes loss of volatiles, oxidation, depolymerization, shrinkage, surface cracking, and embrittlement. Peaking units are more susceptible to thermal cycling damage compared to base-loaded units because of the higher number of start-stop cycles. Repetitive voltage surges can result in turn-to-turn shorts. The first such short may not be evident during operation unless the generator is fitted with a flux monitor. The effects of centrifugal forces are a function of the design of winding bracing system, the properties of the materials used, and the frequency of start and stop cycles.
