What is the dielectric strength of transformer insulation?

The dielectric strength of transformer oil is a critical parameter that determines its ability to insulate electrical components and prevent breakdown. This measurement indicates the maximum electric field that the oil can withstand before it loses its insulating properties. High dielectric strength is essential for transformer oils, as it ensures safe and efficient operation by preventing electrical discharges that could lead to equipment failure. To measure the dielectric strength of transformer oil, Globecore provides advanced testing equipment that delivers precise results, ensuring compliance with industry standards and improving the reliability of transformers. Regular testing of dielectric strength is essential for maintaining the overall health of the transformer and extending its operational lifespan.
