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.

SUBJECTS AND OBJECTIVES

Voltage Regulator Operation – Part 1

  • Describe the function of a voltage regulator.

  • Identify the main components that enable an induction voltage regulator to adjust voltage.

  • Describe how an induction voltage regulator adjusts voltage.

Voltage Regulator Operation – Part 2

  • Identify the main components that enable a step voltage regulator to adjust voltage.

  • Describe how a step voltage regulator adjusts voltage.

Voltage Regulator Control – Part 1

  • Describe the function of a voltage detector, and explain how it works.

  • Describe the function of a line drop compensator, and explain how it works.

Voltage Regulator Control – Part 2

  • Describe the function of a voltage regulator time delay component.

  • Describe the function of voltage regulator limit switches.

  • Describe the function of a voltage regulator voltage reduction control.

  • Describe the function of a voltage regulator first house voltage protector.
