Automatic Step Voltage Regulator (ASVR)

The Automatic Step Voltage Regulator (ASVR) is available in three primary configurations designed to handle extreme input voltage fluctuations and deliver ±1% regulated output voltage.

Product range includes ASVRs in 6 KV, 11 KV & 33 KV systems up to 10000 kVA. Tailor-made HT regulation equipment manufactured to custom industrial specifications.
Voltage System 6 / 11 / 33 kV
Max Rating 10,000 kVA
Regulation ±1% Accuracy
Relay System Automatic OLTC

ASVR Configuration Types

  • Input Variation 15-20%: Step-down transformer is provided with ON LOAD TAP CHANGER (OLTC). Voltage sensing relay automatically selects taps for regulated output voltage.
  • Input Variation > 20%: OLTC is attached with star-connected HV auto transformer having suitable taps in addition to main step-down transformer in common cabinet. Regulated HT voltage (±1%) is fed directly.
  • Existing Installation / High Capacity (>2 MVA): Regulator is built in a separate cabinet consisting of an auto-transformer with OLTC feeding regulated HT voltage to the existing step-down transformer.
