Are there any universal standards for what is considered low, medium, and high voltage as it pertains to transmission and distribution?
I've tried to find the answer, but am getting numbers all over the place with MV starting at 1, 4, or 7kV and HV starting at 36, 45, or 69kV. Are these just arbitrary designations within different POCOs?
Also, does anyone know anything about EHV and SHV as they pertain to transmission lines? Are those terms even used much?
Thanks a lot.
