Different defects in gas insulation substation (GIS) cause several types of partial discharge (PD). A novel on-line PD monitoring technique for GIS is described in this paper. An external sensor is adopted to detect the PD signal and has a wide frequency band. Two kinds of measurement method are used for PD signal acquisition, and high performance hardware units are also employed in order to reflect the true PD characteristics. Based on the idea of combining statistical analysis and high frequency analysis, the analysis level is improved. The developed PD on-line monitoring system has been operating at one 110 kV GIS substation. The results show that the system is effective

In this paper, a type of nano-hybrid polyimide/silica film was prepared by hydrolysis and condensation of methyl-triethoxysilane that served as the precursor of the inorganic moiety and produced the nano-particle of silica, in-situ, in the polyamic acid solution through a sol-gel reaction. The chemical structure and surface morphology of the films were characterized by Fourier transform infrared spectroscopy and Atomic force microscopy respectively. The properties of the films, such as thermal stability and corona-resistance property were investigated as a function of the SiO2 content. The structure-property response on the hybrid system was also discussed. The result of the experiments indicate that the properties of the nano-hybrid materials were not only relative to the inorganic component content of the system, but also to the morphology between the inorganic and organic phases and the character of the interface. It proved that a strong interaction existed between the two phases when a coupling agent is added into the polyimide/silica composite system and that it would play a significant role in improving the miscibility between the two phases, and in reducing the size of the inorganic particles. It also showed that no apparent change had occurred in the thermal decomposition temperature of the hybrid film and the corona-resistance property of the hybrid film had greatly improved as a result of the inorganic component being added into polyimide resin matrix

Bipolar proton exchange membrane (PEM) fuel cell plates are composed of flat pieces of graphite with channels or trenches machined into the face of the plate so that gases can flow in the channels of the plate. The operation of the fuel cell is dependent on the flow of oxygen and hydrogen gases around a fuel cell stack, which is composed of many thin plates connected to each other in very close proximity. Owing to the brittle nature of graphite, fuel cells plates are now made from nickel-chromium alloys that are coated with a thin solid layer of CrN or TiN to improve corrosion resistance. However, nickel-chromium alloys are notoriously difficult to machine. This paper describes the development of micromachining processes that allows fuel cells plates to be machined are very high speeds using novel nanocrystalline diamond and titanium coatings that have been specifically designed to cut strain hardening alloys at extremely high speeds

A 69 MVA pump-generator with corona resistant filled polyimide film applied as stator coil strand insulation has been returned to service. Design modifications were implemented to take advantage of the new insulation system; testing results of these unique 13 kV stator coils are discussed. Operation data from the rewound machine is presented. This is a companion paper to "Application of Corona Resistant Polyimide Film to Pump Generator Stator Coils" presented at ISEI 2004

Results related to the measurement of transient currents recorded after a DC voltage step followed by a short-circuit are reported for both rotor and stator windings for a number of hydro and turbo synchronous rotating machines, motors and generators, in order to assess the quality of the insulating system. Measurements were conducted in the field for windings from different technology yielding different time domain response. Besides reckoning the aging of the insulation, other features such as moisture absorption, end-winding contamination and incomplete curing of the insulating resin (followed by post-curing) were detected in several cases

The most recent issue of NEMA MW 1000, published in 2003 consists of three major parts. Part 1 covers general information about the standard, definitions of terminology and dimensional information that applies to the majority of the standards in Part 2. Part 2 provides specific requirements for more than 60 different magnet wire specifications. Part 3 provides actual test procedures and specific test requirements by AWG size for many of the procedures. Since 2003 there have been a number of changes made in each of these parts of MW 1000. In Part 1, new dimensional requirements have been developed and added for 8-13.5 single build products and additional definitions have been provided for minimum insulation increases and maximum OD's for a number of insulation builds and size ranges. Also, standard dimensions for half AWG sizes have been added for single build from 8-29.5 AWG, for heavy build from 4-29.5 AWG and for triple and quadruple builds from 14-29.5 AWG. In Part 2, several new standards such as MW 37-C and MW 38-C have been added and some of the requirements for other standards have been modified. In Part 3, many tests such as the adhesion and flexibility procedures and requirements have been modified and revised. Finally, some routine test procedures in Part 3 have been reclassified to become periodic test procedures and some periodic test procedures have been modified to allow testing with sizes other than 18 AWG

The paper describes the failure mechanisms of medium voltage inter-turn insulation as a consequence of space charge formation and partial discharge (PD) activity. In order to investigate the failure behavior, models of turn insulation are prepared with magnetic wires having polyimide and nano-filled coating. The ageing of such model bar samples is done under sinusoidal (60 Hz), fast repetitive unipolar voltage pulses and high frequency waveforms. The ageing tests are performed in the presence of PD activity. To establish the residual strength of bar samples, DC breakdown voltages are determined before and after the ageing. Experimental results reveal that the evaluation and analysis of such model study will be helpful for both motor and wire manufacturers to minimize ageing and to improve motor performance under medium voltage inverter-fed drive applications

The advent of organic materials for electroluminescent devices has allowed a wide variety of applications in displays, communications, sensors, and the like. The demonstration of organic magnetic materials has offered the challenge of finding polymer (organic) materials in which there is sufficient electronic exchange as well as stability in both thermally and chemically. The intrinsically conductive and semiconductive polymers have allowed designers the liberties of flexibility and conductivity to meet needs from batteries to solar cells. This paper gives an overview of this search past, present, and future and the synthesis of promising new complex polymer building blocks which can yield conductive, magnetic, semiconductive and luminescent, materials for devices of the future in power, storage, displays, and communications devices. The use of these materials to produce electrically active polymeric materials has changed our way of thinking about how to fabricate devices with novel and useful properties and with properties heretofore unrealizable

The more efficient that farmers farm the more profits they have at sale of their crops. They achieve more efficiency through modern technologies. The technologies include the AFS system by the Case International Company, IntelliSteer by the New Holland Corporation, Fieldstar, Auto-Guide, SGIC systems by the Agco Corporation, and GreenStar system by the John Deere Company. The John Deere Company was formed to manufacture equipment and products, which provide constant improvements in the farming industry. The company is improving the farming industry using a number of Agriculture Management Solutions systems. The systems include the GreenStar system that helps farmers drive a parallel line or drives the line for them using the AutoTrac option. The StarFire position receiver tells the farmer where he/she is in the field from GPS satellites. The JDOffice helps the farm managers keep track of their fields' production and machines. The JDLink sends data from a computer in the tractor to one in the manager's office telling what may be wrong with the machine. With Harvest Doc, the farmer can receive and track information on the yields and moisture content of his crops. These technologies help to keep John Deere in the forefront of farming technology
