Sažetak Cast-resin power transformers are widely used in areas of high standards concerning fire hazards and environmental protection. The most common reason for failures of cast-resin transformers is the electric breakdown of the cast-resin insulation between turns or parts of the windings. In many cases, partial discharges (PD) occur before the breakdown happens. By testing the windings with induced voltage in combination with a sensitive PD measurement, the risk of unforeseen outages can be minimized. Methods for performing the induced voltage test on site with portable equipment and with digital PD instruments for reducing the disturbances are discussed based on case studies.
