Hosted by: Balazs Sztari
Discover efficient ways to enhance laboratory productivity while saving both time and money! Join Transformers Academy's broadcast, where you'll gain insights on elevating quality, minimizing risks, and boosting throughput capacity.
In this exclusive event, Mr. Balazs will delve into strategies for optimizing time and energy utilization, preventing damage, and enhancing overall reliability. He will delve into two crucial aspects of his course: Mechanical tests of power transformers and Testing of auxiliaries of power transformers.
Lesson 19 in the Transformer Testing series focuses on essential testing processes for auxiliaries and various components found in liquid-immersed power transformers. This session is designed to ensure that all auxiliary systems, such as protective devices, metering and signaling devices, built-in current transformers (CTs), cooling devices, and the control and monitoring systems, are functioning correctly and safely. Proper testing and inspection of these systems are critical for ensuring the operational integrity of transformers, especially in high-demand environments.
This lesson is a comprehensive guide to understanding the importance of testing auxiliary systems in transformers, ensuring that all components are functioning properly and safely. By conducting these tests, transformer operators can prevent operational failures, improve safety, and extend the lifespan of the equipment.
