Hi, we are an utility. Someone is concerning 5% overloading of a 115kV underground transmission cable with the overload time duration of 30 min. I know it shouldn't be a concern, as we normally talk about hours in discussing cable's short time overload capacity. Can anyone point to me any references or standards which help to explain the 5% cable overloading for 30 min is not an issue?
