Testing of oil plays a vital role in keeping transformers running efficiently and effectively. Here’s a comprehensive analysis on the different ways to test transformer oil.
The growth is due to the increase in HVDC transmission projects mainly in the Asia-Pacific region. HVDC, EHV, and UHV projects being undertaken for reducing transmission losses during transmission over large distances is the major growth driver of the large power transformer market.
The article focuses on basic design changes and materials being addressed to bushing apparatus used on power transformers in high voltage substations.
Utilities and transformer manufacturers focus on the design and manufacture of environmentally-friendly transformers that are nonhazardous while offering improved life cycle costs with minimal maintenance. These transformers offer reduced carbon footprint, reduced levels of pollution (water, soil, noise), enhanced lifecycle costs, enhanced product lifetime, and enhanced fire safety…
Particles in the transformer oil adversely affect the dielectric strength of the insulating oil. Depending on type, size and quantity of particles (metallic, water etc.), a flash-over could be generated, which can be hazardous…
