Electrical Diagnostic Testing on Transformers & Breakers

Сводка

The training participants will learn how to perform and assess many of the conventional electrical diagnostic tests recommended for power transformers and circuit breakers. The training focuses on the diagnostic testing that can, and should, be performed during regular maintenance intervals to ensure that these Assets are in good condition and can continue in-service life with minimal risk.

Learn how to efficiently and effectively utilize the TESTRANO 600, CPC 100, CIBANO 500, and Primary Test Manager to test transformers and breakers via hands-on and theoretical sessions.

Цели

• Introduce the key components of a power transformer (core, insulation, windings, bushings, tap changer) and circuit breaker (control circuits, coils, main contacts, insulation, bushings)
• Discuss the theory and application of many industry accepted, widely used electrical diagnostic tests
• Learn how to analyze the measurement results to properly assess the condition of these Assets
• Learn to safely and efficiently operate the software and test equipment to obtain the correct measurements
• Discuss the most common mistakes that users make in the field
