Answer Posted / jawwad siddique
A surge capacitor is used to mitigate (minimize) voltage
surges. Capacitor impedance can be modeled as 1/jwC, j = i =
imaginary value used in vectors, w is the frequency, and C
is the capacitance. A fairly small capacitor on the input to
a power supplying circuit will have a large impedance, and
so will impact the circuit operation very little due to the
low power frequency. Surges are high frequency. When a surge
occurs, the capacitor impedance appears much smaller to the
high frequency surge, effectively shunting the surge energy
to ground; this minimizes the surge with respect to the
protected circuitry.

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
