What is the dielectric strength of a transformer?

The dielectric strength of a transformer refers to the maximum electric field that the insulating material within the transformer can withstand without breakdown or failure, often measured in kilovolts per millimeter (kV/mm). This property is crucial as it determines the transformer’s ability to operate safely under high voltage conditions, ensuring efficient performance and longevity. For accurate testing of dielectric strength in transformers, Globecore offers advanced dielectric strength testers that are essential for assessing dielectric integrity and ensuring compliance with industry standards. These testers enable users to effectively measure the dielectric strength of transformer insulation, helping to prevent potential failures in electrical systems.
