Power transformer diagnostics with the CPC family
After an introduction to the maintenance of transformers, you will expand your knowledge of transformer diagnostics and applications in theory and practice. You will get familiar with the CPC 100 and CP SB1 functions for turns ratio, winding resistance and using the CP TD1 for capacitance or power/dissipation factor measurements. Practical measurements will enable you to gain immediate testing experience.
