Guidelines for transformer application designs. | EC&M price of these units typically ranges from 15% to 40% higher than that of silicon steel core transformers. To a degree, the price differential is dependent upon which grade of silicon steel the comparison is being made. (The more energy efficient the grade of steel used in the transformer core, the higher the price of the steel.)

Electrical substation - Wikipedia substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

Electrical Insulation Magazine - Mar/Apr 2019 - IEEE DEIS 5, testing and analysis of UHVDC systems, consists primarily of the effects of overvoltages on parts of a UHVDC system (i.e. connecting/disconnecting converter transformers, overvoltages on the AC side and DC side of the substation). Chapter 6, digital simulation, shows how to set up circuits to create overvoltage models in a power system.
