Rotary converter plant

A rotary converter plant is a facility at which rotary converters convert one form of electricity to another form of electricity. The installed combinations of motors and generators at a plant determine the possible type(s) of conversion. Such facilities also allow the setting of voltages and frequencies, if appropriate equipment is installed. Rotary converter plants were commonplace in railway electrification before the invention of mercury arc rectifiers in the 1920s.
