ABSTRACT:
A voltage regulator controller is provided with multiple control programs. At any given time, one of the control programs is selected to be "active" depending on the existing operating conditions. An operator (user) configures the voltage regulator control to change its active control program based on a number of factors, which can include, for example, demand metering values, the time and/or date, external inputs such as the measured transformer oil temperature, commands received via a serial communications port and fault/maintenance status. In a preferred embodiment, the configuration settings for activation are handled in accordance with a priority scheme when more than one of the conditions occur simultaneously.
