Power transformer diagnostics with CPX 200

Summary

Learn how our multifunctional CPX 200 test device makes commissioning, maintenance, and condition assessment of power transformers easier, faster, and safer. Familiarize yourself with simplified tests, precise measurements, and guided workflows for evaluating power transformers condition according to international standards.

Objectives

• Perform commissioning, troubleshooting and periodic tests of Power transformers winding and insulation system
• Intuitive generation of asset-specific test plans, including wiring diagrams
• Automatic evaluation of results: automated assessments in accordance with industry standards
• Straightforward reporting and automatic test data synchronization to manage all data on one platform

 

Content

• Negative influences on the expected lifetime of a power transformer
• Overview of frequent defects in transformer components and their fault patterns
• Construction of the transformer insulation, the bushings and the tap-changer
• Common conventional measurements such as Turns ratio, Winding resistance, Short-circuit impedance and Demagnetization of the power transformer
• Capacity and dissipation/power factor measurement of winding and bushing insulation
• Evaluation of the measurement results by means of practical examples
• Assessment of diagnostic measurements and recognizing possible defects and influences
• Analyzing case studies of most common defects on various power transformers
