WebMay 1, 2008 · For these calculations, the fault current is held constant at 30,000A. This graph clearly demonstrates that the device operating time has a major impact on the calculations. ... Another method of reducing the fault current is the use of current-limiting reactors. These devices have been used in many facilities to reduce the fault current to ... WebCurrent limiting fuses operate in two modes, depending on the magnitude of the fault current. The first is operation in the overload mode where the fault current is below the threshold current for the fuse. In this mode, the fuse does not operate during the first major half cycle, and does not limit the magnitude of the fault current.

In the absence of an iron core, there is no saturation of the core. These reactors are more useful when they are required to be used as current limiting devices as for limiting the inrush currents during switching of large capacitor banks (Section

WebOct 4, 2007 · Current flowing through an impedance creates a voltage drop (V = IZ), watt losses (watts = I x I x R) and vars ( vars = I x I x X). In a current limiting reactor we want to keep the watt losses as low as possible (low R) and use the Var "losses" to restrict current flow. (Vars aren't really lost.
