Sažetak

Dielectric tests have been used for decades for diagnosis of power transformers and bushings. In addition to the traditional tests at line frequency, modern types of dielectric tests using different frequencies and voltages have evolved. The article considers the scope of this principle, explaining the most common test procedures and describing what information can be derived from the measured values.
