We used electrical, metallurgical and chemical techniques to measure the electrical, chemical, dielectric and metallurgical properties of paper-impregnated insulation. The nondestructive electrical tests performed on three full-length field-aged PILC cables were: the isothermal relaxation current (IRC), the LIpATEST leakage current test and the return voltage method (RVM). Chemical tests were performed on small samples of paper tapes and oil taken from the same samples. They were: dielectric analysis, Fourier transform infra red (FTIR) spectroscopy and moisture content analysis. The electrical techniques ranked the cables consistently, that is one cable aged 23 years seemed to be more severely aged than the older (34 years) and younger (4 years) cables. This could possibly be explained by the acids detected in the oil of the 23 year old cable using FTIR spectroscopy. Although more data on more cables would be needed it already appears that the tested techniques could assess the condition of the insulation of PILC cables. Water ingress is often associated with cracks in the lead sheaths due to fatigue and creep failure. Metallurgical tests were performed on the lead sheaths of four PILC cables and they revealed that artificial cracks of different depths introduced on the surface of the lead sheaths were easily detected by the visual and fluorescent dye penetrant inspections. An eddy current inspection technique was successful in detecting the artificial surface flaws on the lead sheaths. The hardness of the older lead sheath, as measured by the Brinell test, tends to be lower than that of the lead sheath of the younger vintage cables.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.

The influence of the soil resistivity and different grounding system configurations on the structure surge impedance has been studied. The structure surge impedances are computed for three impressed surge current waveforms: (a) step current wave; (b) ramp current wave; and (c) typical double-exponential lightning surge current. The computed surge impedances using the electromagnetic field approach are compared with those obtained using formulae based on a geometrical model of the power line structure. It is shown that the computed values based on the electromagnetic field theory are, to various degrees, different from the values computed using the formulae based on the geometrical model of the structure. The study also reveals that: (a) the surge impedance of a lattice steel tower decreases only slightly when the soil resistivity is increased from 0.1 /spl Omega/-m to 500 /spl Omega/-m; and (b) when the footing resistance is held constant, the surge impedance of a single pole changes by about 5%, when counterpoises instead of rod clusters are used.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.

A near real-time information management strategy must be assembled as an integrated whole to build a cost and benefit-justifiable business case. The strategy typically incorporates several new and adjusted business processes along with enabling technology infrastructures. A key to successful development of a near realtime information management strategy is viewing end-to-end components, such as near real-time information acquisition, delivery, aggregation, analysis and integration as a single enabling platform for many key utility business processes. As in justifying financial investments for geospatial information systems and enterprise integration systems, near real-time information management will be ultimately justified through the required applications-enabling infrastructure. This presentation highlights processes that can be enhanced via near real-time information integration, along with the enabling technology infrastructures, as examples of components required for development of a near real-time information management strategy.","PeriodicalId":182269,"journal":{"name":"2001 IEEE/PES Transmission and Distribution Conference and Exposition.
