Power transformers are among the most critical components of modern electrical power systems. Their ability to withstand electrical stresses caused by operating voltages, lightning surges, and switching operations depends on the integrity of their insulation system. To ensure reliable and safe operation, every transformer must successfully pass a series of dielectric tests specified by international standards.
This comprehensive course is designed to provide a practical and in-depth understanding of IEC 60076-3 and IEC 60076-4, the internationally recognized standards covering insulation levels, dielectric tests, and lightning and switching impulse testing of power transformers. Rather than simply reading the clauses of the standards, this course explains the engineering concepts behind each requirement in a clear and easy-to-understand manner.
You will begin by learning the fundamentals of transformer insulation coordination, insulation levels, and dielectric withstand requirements. The course then explains the various dielectric tests specified in IEC 60076-3, including applied voltage tests, induced voltage tests, lightning impulse tests, and switching impulse tests.
