SINGLE PHASE STEP VOLTAGE REGULATOR
Farady Electric
Co.,Ltd VR-8 single phase step voltage regulators are tap-changing
autotransformers. They 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. Smaller kVA sizes are
supplied with support lugs for pole mounting and with substation or platform
tie down provisions. Larger sizes are provided with substation bases with
pad-mounting provisions
