Step voltage regulators can improve the utility's return on investment by increasing demand at off-peak periods and, with certain accessories, even reduce the peak demand load. This translates into improved revenue for the utility company while also improving the quality of service to the customer.

The step-type voltage regulator takes an incoming voltage that will vary with load conditions and maintains a constant

output voltage. As the loading increases along the distribution feeder, the voltage will drop. This reduction in voltage

reduces the amount of power used by the lighting portion of the load. By increasing the voltage to this load, additional power is consumed. This increased power translates into increased revenue for the utility company. The same principle can

work for the utility company when it needs to reduce the voltage by a predetermined amount, thus reducing the overall power demand and delaying capital investments to meet peak demand.

  • Type-316 stainless steel external hardware to eliminate rust and galling

  • Oil-sight gauge allows oil levels and oil conditions to be checked without de-energizing the regulator.

  • Motor capacitor installed in the control cabinet allows replacement without bypassing and transitioning the regulator out of service.

  • Oil-drain valve includes an oil sampling valve for easy access.
