Montana-Dakota Utilities - Sterling, ND
As the years go by, there are fewer and fewer substations still configured to put out 2400 volts delta, which was THE standard distribution voltage in the early 1900s.
MDU recently replaced the multipart insulators on the 41.6kV arm, but the circuit coming out of the sub is 2400V... for now. (MDU has also been steadily changing over its 2400V and 7200V delta systems to 4160V and 12.5kV respectively)
