Questions & Step-by-Step Solutions
Which type of fault is most common in transmission lines?
Step 1: Understand what a fault in a transmission line is. A fault is an abnormal condition that causes a disruption in the flow of electricity.
Step 2: Learn about different types of faults. There are several types, but the most common ones are single line-to-ground faults, line-to-line faults, and three-phase faults.
Step 3: Focus on single line-to-ground faults. This type occurs when one conductor touches the ground or a grounded object.
Step 4: Know why single line-to-ground faults are common. They often happen due to insulation failure (when the protective covering of the wire breaks down) or external factors like trees falling on the lines.
Step 5: Conclude that single line-to-ground faults are the most frequent type of fault in transmission lines.
