The Bussmann Short Circuit Calculator is a valuable tool used in electrical engineering to determine the short-circuit current in a circuit. It plays a crucial role in ensuring the safety and reliability of electrical systems by helping engineers and electricians analyze potential faults and protect equipment from damage.
Formula of Bussmann Short Circuit Calculator
The formula for the Bussmann Short Circuit Calculator is as follows:
Isc = V / (Zs + Zb)
Where:
- Isc is the short-circuit current (in amps).
- V is the system voltage (in volts).
- Zs is the total impedance of the circuit up to the point of the short circuit (in ohms).
- Zb is the impedance of the equipment beyond the point of the short circuit (in ohms).
This formula allows users to input the system voltage, total impedance, and equipment impedance to calculate the short-circuit current accurately.

Example of Bussmann Short Circuit Calculator
Suppose we have a system with a voltage of 480 volts, a total impedance of 2 ohms, and an equipment impedance of 1 ohm. Using the Bussmann Short Circuit Calculator, we can determine the short-circuit current as follows:
Isc = 480 / (2 + 1) = 480 / 3 = 160 amps
Therefore, the short-circuit current in this example is 160 amps.
