Webimpedance. When a short circuit fault occurs in a distribution system the fault current that flows is a function of: 1. the internal voltage of the connected machines in the system (generators and motors), 2. the impedance of those machines, 3. the impedance to the point of the fault, mostly cable impedance, WebDec 7, 2024 · Assuming a maximum transformer design impedance of 10.5% (or on a 24 MVA base, we can calculate the impedance of the current limiting reactor as at 24 MVA. To reflect this value on our 40 MVA base, we multiply by the ratio of the two bases, giving us an impedance of = 0.1725 = 17.25% at 40 MVA chinese movie streaming sites https://waldenmayercpa.com
