Brad . Calhoun. Consultant, Sr. . Trainer. Spring 2016. Introduction. Voltage control in an electrical power system is important for proper operation of electrical power equipment, to prevent damage such as overheating of generators and motors, to reduce transmission losses, and to maintain the ability of the system to withstand and prevent voltage collapse. In general terms, decreasing reactive power causes voltage to fall while increasing it causes voltage to rise. A voltage collapse occurs when the system try's to serve much more load than the voltage can support.. Mike Tachick. Dairyland. Electrical Industries Inc.. Western Regional Gas . Conf. – Aug 2012.
