VR-8 single-phase step voltage regulators are tap-changing autotransformers designed to automatically regulate distribution line voltages in a range of plus or minus 10% in 32 steps of approximately 5/8% each. The following ratings are available:
A digital control system automatically operates the tap changer mechanism to maintain system voltage within desired limits. The control system is externally programmable to allow precise setting of control limits and provides sophisticated capabilities for special control requirements, communication, and data logging.
