    The water concentration in transformer paper insulation must be monitored because, if it becomes too high, the paper insulation will age rapidly [1]-[4] and the transformer may fail on overload [5]-[9]. A failure can occur on overload if the temperature of the paper rises sufficiently to cause evolution of water bubbles. If these bubbles cause dielectric failure of the oil gap, the transformer may... View full abstract»

    Very fast transient overvoltages (VFTOs) may be generated in SF6 gas insulated switchgear (GIS) due to a series of arc ignitions and extinctions, during the operation of disconnecting switches and circuit breakers. They may also occur during internal flashover in the GIS. Some recent reports of failures in power transformers suggest high internal overvoltages associated with arc restrik... View full abstract»

    Many electric utilities, including Memphis Light, Gas & Water (MLGW), began installing underground residential electric (URD) facilities in the late 1960s. The earliest URD customers at MLGW were served by paper-insulated lead-covered (PILC) type cable which has a very good service history but was expensive and time-consuming to install. In an effort to install URD facilities at a comparable cost ... View full abstract»

    Aging of power transformers is one of the biggest challenges electrical utilities face. As transformers are commissioned, their insulation system composed of liquid (oil) and solid (paper and pressboard) insulations will deteriorate over time, jeopardizing longevity and reliability of transformers. As a means for optimizing capital expenditure without undermining the reliability of electricity sup... View full abstract»
