Power transformer diagnostics with the CPC family

主要特点

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.

学习目标

• Get a comprehensive overview of the structure of the transformer insulation, the bushings and the tap-changer
• Analyze the condition of power transformers to fully exploit the lifetime of your asset
• Carry out time-optimized tests and diagnostics in the substation, power station or workshop
• Perform fast, simple and safe condition assessment of your power transformer

 

内容
