Product Description: VR-32 single-phase step voltage regulators from Cooper Power Systems are tap-changing autotransformers. Voltage is maintained within desired limits by controls that feature superior accuracy, reliability, and serviceability. Continuity of service is assured by rugged, service-proven tap changers and core-and-coil assemblies functioning with the control.
Cooper Power Systems voltage regulators are available with a full complement of standard features for routine applications, as well as a full line of option-al accessories for unique applications. In addition, the regulator offers desirable features that enhance operation and service.
FEATURES
- Regulate distribution line voltages from 10% raise (boost) to 10% lower (buck) in thirty-two steps of approximately 5/8% each.
- Voltage ratings are available from 2400 volts (60 kV BIL) to 34,500 volts (200 kV BIL) for 60 Hz and 50 Hz systems.
- Internal potential winding taps and an external ratio correction transformer are provided on all ratings so that each regulator may be applied to more than one system voltage.
