To achieve the required level of product quality it is essential that manufacturing organizations have in place a reliable and accurate measurement system. This measurement system not only includes the various devices and equipment used to directly inspect the product, but also includes the control system and personnel involved in the quality process. Therefore, it is necessary for manufacturing organizations to \"inspect\" the measurement system to insure consistency and reliability measurements. Measurement system assessment fulfills this need and contributes to the ultimate goal of a quality product. This paper investigates measurement system assessment concepts such as repeatability, reproducibility, accuracy and guard banding. Numerical analysis methods used in measurement system assessment are introduced to determine the reliability of inspection procedures and equipment in terms of conformance to desired standards. This paper also investigates inspection equipment issues such as gage accuracy, stability, discrimination and linearity.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

When considering Ni-MH batteries for application in severe operating environments, such as those requiring high-current, rapid discharge operations, the battery temperature is the limiting factor. Battery temperature control during charging can be accomplished by utilizing proper charging algorithms and/or charging systems that incorporate temperature measurement as a control factor. However, during discharge in severe operating conditions where limiting current draw in not possible, a temperature control system must be developed. For electric and hybrid vehicle applications, the temperature control system must have operating characteristics including lightweight and little or no power consumption required. To fully evaluate Ni-MH batteries in high-current discharge operating regimes, researchers at IUPUI first modeled the battery using Inertia(R), a finite element analysis (FEA) software package. Using the FEA results as a basis, a temperature control strategy was developed and a battery pack cooling system designed. As a validation method of the FEA model, bench testing of Ni-MH modules was conducted. This paper reports on the FEA modeling along with the results of the bench testing of the batteries in this severe operating regime.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

This robot processes information from its various sensors and key hardware elements via a Motorola 68HC12 micro-controller with 64 kB of expanded memory. It uses UV, IR and visible light to detect various components of its environment.

The final failure mechanism has consisted of a turn-to-turn fault, usually in the valve winding. All the windings were produced using continuously transposed conductors. Thermal aging of the insulating materials was evident. This paper summarizes the results of the various tests and inspections that were made in an attempt to better understand the circumstances that may have contributed to these failures. On-line partial discharge measurements using an electrical detection method are being made on a periodic basis on a number of large power transformers, primarily those used in HVDC conversion.

The results of several diagnostic tests on aged and unaged bushings are described in this paper. The test techniques include tan delta and loss current waveforms at 60 Hz, dielectric spectroscopy from 0.1 to 100 Hz, and recovery voltage. The results show that some of the techniques were able to detect significant changes in aged bushings, particularly at high temperatures. Further work is, however, recommended to improve our understanding of the changes in parameters such as loss current waveform, low frequency tan delta, and recovery voltage.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.
