Smart automatic voltage regulator
Single phase
Rated voltage: 14.4kV; 19.92kV; 7.62kV; 13.8kV
Standard: IEC, ANSI, GB

General

UNAVR single phase step voltage regulators are tap-changing autotransformers.

It regulates 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.

Standard
All UNISUN transformers are in conformity with IEC standards, Transformers in conformity with specific country standards can also be supplied. (IEEE, GB)
