Transformers and Their Role in Enhancing Power QualityTransformers are fundamental components in power systems, playing a critical role in maintaining and improving electrical power quality. Power quality refers to the degree to which electrical energy conforms to defined parameters, including voltage stability, frequency, waveform integrity, and reliability. This article explores the significant contributions of transformers to power quality improvement.Voltage RegulationOne of the primary func

What is GIS Equipment?GIS is the English abbreviation for Gas Insulated Switchgear, which is fully translated into Chinese as Gas-Insulated Metal-Enclosed Switchgear. It typically uses sulfur hexafluoride (SF6) gas as the insulating and arc-quenching medium. GIS integrates, through optimized design, the main primary equipment in a substation—excluding the transformer—such as circuit breakers (CB), disconnectors (DS), earthing switches (ES/FES), busbars (BUS), current transfor

Hazards of Multi-Point Grounding Faults in Transformer CoresDuring normal operation, transformer cores must not be grounded at multiple points. The windings of an operating transformer are surrounded by an alternating magnetic field. Due to electromagnetic induction, stray capacitances exist between the high-voltage and low-voltage windings, between the low-voltage winding and the core, and between the core and the tank.The energized windings couple through these stray capacitances, causing the

Power transformers are critical components within the power grid. Once quality issues occur, they may not only result in significant economic and property losses but also endanger lives and cause immeasurable negative social impacts.Generally, the reliability of a power transformer is primarily influenced by its design, technology, materials, and manufacturing standards. Among these, design—being the foundation of product quality—plays a crucial role in determining the overal
