What are short-circuit currents in the context of LMS Substation 2-2?

Short-circuit currents refer to the excessive currents that flow through a circuit when there is a fault condition, such as a short circuit. During such faults, the normal path for the electrical current is interrupted, leading to a sudden and significant increase in current levels that can cause severe damage to electrical equipment and systems. Recognizing and understanding short-circuit currents is crucial for designing protective measures, such as circuit breakers and fuses, which are essential to ensure safety and reliability in power distribution systems. This concept is fundamental in substation design and operation within the LMS context, as it helps engineers assess the potential impacts of fault scenarios and implement adequate protection strategies.
