Gujarat electronics & controls supplies highly precision servo-controlled voltage stabilizers. These units are available in both single phase as well as three-phase model with balanced load or unbalanced load.The output vaoltage of these voltage stabilizers is maintained at 230 ±1 per cent or 415 ±1 per cent. Rate of correction is fairly fast. A voltmeter is provided to observe the input as well as output voltage. Provision for manual operation is also provided along with solid-state control of servomotor. There is radio interference or waveform distortion, insensitive to load power factor. Additional facilities, like overload trip facility, auto/visual alarm from over/under voltage, digital voltameter, ammeter can be provided. The servo controlled voltage stabilizers are available up to 15 kv a in single-phase and up to 100 kv a in three phase. They are tested at erda, vadodara.
