Job Description:

• 1) Inspects, tests, and maintains voltage regulators and auxiliary equipment that control line voltage within specified range: Tightens connections and replaces defective regulator parts, such as motor controls, fuses, or capacitors.

• 2) Observes readings and calculates line-drop compensator settings which allow for resistance and reactance voltage drops in primary feeder and main circuits.

• 3) Adjusts line-drop compensators and reads meters to sustain voltage within specified range.

• 4) Computes electrical characteristics, such as impedance, power factor, and phase angle.

• 5) Oils moving parts of regulator and changes oil in motor-bearing housings.

• 6) Files contact points to remove carbon and provide smooth surface for electrical contact.

• 7) Clips voltmeter to regulator and records voltage on inspection report.

• 8) Sends defective motors and parts to repair department.

• 9) May make voltmeter and ammeter tests on transmission lines and auxiliary equipment.

• 10) Compiles service report indicating parts replaced and corrections made in voltage range and transformer ratios.

• 11) May order replacement parts to replenish inventories.

• 12) May set regulator to deliver specified constant voltage before removing motor for repair to avoid interruption to service.
