Power Transformers are essential components of electrical power grids. The useful life of a power transformer is effectively determined by the state of its insulation system. The insulation system deterioration is directly correlated to the temperature at which it is operated. Maintaining the temperature of power transformers within an optimalRead More →
Co-authored (2 out of 8 chapters) by the Engineers Tools founder the “Power Transformer Condition Monitoring and Diagnosis” book provides a useful account of modern condition monitoring techniques for Power Transformers. Quoting from the Institution of Engineering and Technology who publishes this book: Topics covered include concepts and challenges in powerRead More →
The Harmonics Visualiser tool is an Excel workbook that presents the vectorial and sinusoidal representation of a system of harmonic components. The magnitude of the vectors can be entered on the left-side of the graphs and the angles are calculated automatically depending on the order of the harmonic component. TheRead More →
