// Given data
kV = 132.0        // Voltage(kV)
C = 0.01*10**-6   // Phase to ground capacitance(F)
L = 6.0           // Inductance(H)
i = 5.0           // Magnetizing current(A)

// Calculations
V_pros = i*(L/C)**0.5/1000    // Prospective value of voltage(kV)
R = 1.0/2*(L/C)**0.5/1000     // Resistance to be used across the contacts to eliminate the restriking voltage(k-ohm)
