Proper reactive power management for improving the a.c power system performance always result in loss minimization. It is all about the supply of reactive power in a transmission line to increase the transmittable power thereby making it compatible with the prevailing load demand. In this paper, various factors contributing to loss minimization in a.c networks were examined, and include the use of: shunt capacitors and reactors, synchronous capacitors, tap changing transformers, series capacitors e.t.c. Recommendations to minimize losses in the system were proffered in this study to ensure good power quality and security in the network.
