Voltage level, transformer rating, substation location and redundancy are all fixed on the medium voltage single line diagram. Here is the order in which those decisions have to be made, and what belongs in the specification.
Pulse number is the single design decision that controls harmonic current in a rectifier transformer. Here is how 6-, 12- and 24-pulse arrangements differ, what the 30 degree phase shift actually cancels, and what to put in a specification.
Rectifier transformers are critical components in aluminum smelting plants. Learn about their design requirements, technical specifications, cooling systems, and how they support high-current electrolysis processes.
Cast resin transformers are a type of dry type transformer with epoxy resin insulation. Discover their key advantages, industrial applications, design considerations, and how they compare to oil immersed transformers.
Custom transformers are essential for unique industrial applications where standard products cannot meet specific requirements. Learn about the key design considerations, engineering process, and benefits of custom transformer solutions.
A marine transformer is a specialized electrical transformer designed for use on ships, offshore platforms, and other marine applications. Learn about its working principle, design requirements, and key applications in the marine industry.
High current design is not ordinary transformer design scaled up. Above a few thousand amperes, effects that are negligible in […]
A special transformer exists because a standard one cannot do the job. In practice that means one of four things: […]
Standard or custom is not a question of quality. A catalogue transformer from a competent manufacturer is a better purchase […]
A special transformer specification is a technical document, and it works when it defines the problem and leaves the solution […]
