Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFSeries Compensation in transmission line:
- The series compensation in a transmission line is achieved by connecting a capacitor in series with the inductor.
- By connecting the capacitor in series with the inductor, the net reactance of the line decreases.
- As the power in the transmission line is inversely proportional to the reactance, the power flow increases in the line.
- But if the degree of compensation and location of capacitors are not proper, series capacitors produced high recovery voltages across the breaker's contact.
- Hence, the distance relays used for line protection may not function properly.
