Normally, hydrocarbon mineral oils are used as transformer oil. Oil contamination is a serious problem because contamination robs the oil of its dielectric properties and renders it useless as an insulating medium.CHAPTER 15 DISTRIBUTION TRANSFORMERS15.4 CHAPTER 15. winding. The windings of the transformer are constructed with sufficient turns in each winding to limit the no-load or exciting current and produce a countervoltage approxi- mately equal to the applied voltage. The exciting current magnetizes, or produces a mag- .Capacitor Coupled Voltage Transformer (CVT or CCVT ...The Capacitor Voltage Transformer (CVT) or Capacitor Coupled Voltage Transformer (CCVT) is a switchgear device used to convert high transmission class voltage into easily measurable values, which are used for metering, protection, and control of high voltage systems.Power Transformer Construction - The CoreThe construction of a power transformer varies throughout the industry.
