Derive expression for the restriking voltage
WebThe natural response of an \text {LC} LC circuit is described by this homogeneous second-order differential equation: Where \omega_\circ =\sqrt {\dfrac {1} {\text {LC}}} ω∘ = LC1 is the natural frequency of the \text {LC} … Webrestriking ground fault after two strikes (restrikes). Figure 6: Following each line-to-ground restrike, the neutral to ground voltage jumps to an even higher voltage value. After only two line-to-ground strikes the neutral has shifted from 0 volts to 660V and then to 1.16 kV (I).
