Voltage Regulators 1
COURSE DESCRIPTION
Utilities are required to provide power to their customers within a specific range of voltages. Voltages that are outside of that range may damage equipment or cause it to operate inefficiently. One method of maintaining voltage within a specified range is by using voltage regulators. This program discusses the operation and control of substation voltage regulators.
COURSE GOALS
Describe why voltage regulation is needed in a transmission and distribution system.
Identify the main components of induction voltage regulators and step voltage regulators, and explain how each operates.
Describe voltage regulator controls, and explain how each of these controls operates.
