high voltage testing of transformer ppt

Abstract

As transmission voltages have increased it has become necessary to carry out fundamental research work on transformers outdoors with all the attedant problems of weatherproofing. New core and insulating materials point to the possibility of smaller and lighter transformers so that indoor installations can be used ....etc

High Voltage Transformer

Such transformers are normally used in high voltage laboratory for testing purpose. This transformer is subjected to transient voltages and surges during their normal operation when the insulation under test breaks down. To withstand these impulse voltages, the insulation of transformer is carefully designed. This high voltage transformer is single phase, core type. This type of transformer is generally oil immersed. Bakelite sheets are used for separating high tension and low tension winding. The high voltage transf ....etc

Abstract

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components voltage ratings and energy volumes of passive components of the proposed converter are greatly reduced c ....etc

This paper outlines design, manufacturing, testing and service maintanence of high voltage bushing used in Power Transformers. Particular importance is given to Oil Impregnated paper condenser bushing which is generally used. International as well as national standards define bushing as ?a structure carrying one or several conductors through a partition such as a wall or tank and insulating it or them there from, incorporating the means of attachment (flange or other fixing device) to the partition.? The conductor may form an integral part of t ....etc
