Calculation of transformer rated current and computer protection setting value
Original link: https://www.nwazi.com/post/weiji.html 1. Calculation of high and low voltage side current, transformer capacity/voltage level/1.732*rated current For example: Transformer capacity is 1000kVA High voltage side current: 1000/10/1.732=57.736A Low voltage side current: 1000/0.4/1.732=1443.418A 2. Calculation of the protection setting on the high voltage side of the transformer: For example: the capacity of the transformer is 1000kVA, […]
