Sobre este producto
- This handbook is systematically divided into seven chapters, each dedicated to an essential and widely-utilized diagnostic electrical test of power transformers. These tests are addressed both theoretically and practically, with reference to esteemed standards and guidelines issued by leading institutions and organizations, such as the Institute of Electrical and Electronics Engineers (IEEE), the International Electrotechnical Commission (IEC), and the International Council on Large Electric Systems (CIGRE). Moreover, the content is enriched by practical insights gained from my extensive experience as an electrical maintenance engineer at prominent power generation plants in Jordan. The chapters are organized as follows:Insulation Resistance Test.Winding Resistance Test.Turns Ratio Test.Dissipation/Power Factor and Capacitance Test.Excitation Current Test.Leakage Reactance Test.Sweep Frequency Response Analysis Test.To enhance comprehension, the elucidation of these tests is structured as follows:General Introduction: An overview of the test, including its importance and the specific part of the transformer it assesses. This section provides the foundational knowledge necessary to understand the context and relevance of the test within the broader framework of transformer maintenance.When To Do the Test: Identification of several reasons prompting the conduction of this test, among which are routine assessments for ensuring the transformer's integrity, diagnostic purposes to identify faults in the transformer, or other specific reasons.Why To Do the Test: Description of the faults that can be detected utilizing the test and the indicators/events necessitating its conduction.Test Philosophy: Detailed explanation of the test's principles, methods, techniques, and connections, along with any pre-test considerations. This section delves into the theoretical background, the physics of measurement, and the technical setup required to perform the test. It includes diagrams and schematics to aid in understanding the procedures.Test Procedures: Step-by-step instructions for conducting the test, covering aspects of the testing process, from initial preparation to the execution and recording of results. Safety precautions and best practices are also highlighted to ensure accurate and reliable measurements.Test Results Correction: Guidance on correcting measured values using equations and tables, in line with international standards and references.Test Results Interpretation: Comprehensive analysis of the corrected values, referencing standards, literature, and practical experiences. Providing insights into the condition of the transformer and recommending subsequent actions based on the analysis.Influencing Factors: Identification of several factors may influence the test results, necessitating a thorough consideration to eliminate, or at least mitigate their influence on test results.Factory Test Examples: Examples of factory acceptance test results for illustration.Annexes: Supplementary information and tables useful for test connections or results correction.This structured approach aims to provide electrical maintenance professionals with a comprehensive and practical guide, ensuring the effective monitoring and maintenance of power transformers to support the reliability and efficiency of the electrical power system. Through detailed explanations, practical insights, and thorough analysis, this handbook serves as an important resource for those tasked with maintaining the backbone of our electrical infrastructure.
