Technical Specification<\/h2>\n

*VR-8 single-phase step voltage regulators are tap-changing autotransformers designed to automati- cally 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:<\/em><\/p>\n

\u2022 Voltage: 2500 Volts (60 kV BIL) through 34500 Volts (200 kV BIL)<\/em><\/p>\n

\u2022 Current: 50 through 1665 Amps<\/em><\/p>\n

\u2022 KVA: 33 through 1000<\/em><\/p>\n

\u2022 Frequency: 50 or 60 Hertz<\/em><\/p>\n

Internal potential winding taps and\/or an external ratio correction transformer are provided on all ratings so that each regulator may be applied within a range of system voltages.<\/em><\/p>\n

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 require- ments, communication, and data logging.<\/em><\/p>\n

Overhead type voltage regulators are supplied with support brackets for pole mounting and have bolt-down provisions for pad-mounted applications. Substation type voltage regulators are provided with rectangular substation bases. Elevating platforms are available as an option.<\/em><\/p>\n
