Type (a) – Standard Regulation

• Designed for systems with input voltage variation of 15–20%.
• Features OLTC-based regulation, automatically maintaining constant output voltage within the rated range.

Type (b) – Wide Range Regulation

• Engineered for input fluctuations exceeding 20%.
• Equipped with OLTC and star-connected high-voltage autotransformer housed in a single cabinet, ensuring seamless regulation through automatic tap selection.

Type (c) – High-Capacity Systems

• Ideal for installations with a step-down transformer or transformer capacities above 2 MVA.
• Uses a separate cabinet with auto-transformer and OLTC to regulate HT voltage supplied to the step-down transformer, optimizing large-scale power distribution systems.

• Voltage Regulation Range:
  • Type A: 15–20%
  • Type B: >20%
  • Type C: Variable, depending on transformer capacity
• Tap Changing Mechanism: On-Load Tap Changer (OLTC)
• Transformer Configurations:
  • Step-down transformer
  • High-voltage star-connected autotransformer
  • Auto-transformer with OLTC (for Type C)
• Capacity: Suitable for transformers above 2 MVA (Type C)

• Stable Output Voltage: Protects sensitive equipment and machinery from damaging fluctuations.
• Automated Regulation: Real-time OLTC operation eliminates manual intervention.
• Enhanced Equipment Life: By maintaining consistent voltage, ASVR reduces thermal and electrical stress on downstream systems.
• Optimized Performance: Ensures reliable operation for power-intensive industries with unstable grid conditions.

• Industrial Plants – Protection of heavy machinery and sensitive equipment from power fluctuations.
• Utility & Distribution Systems – Stabilizing high-tension networks for reliable supply.
• Large Transformers (2 MVA and above) – Custom high-capacity regulation solutions.
• Sectors with Unstable Power Supply – Steel, cement, chemical, and processing industries.

• Certifications: IS/2026, IS/1180, IS/11171
• Quality Assurance: Each ASVR undergoes rigorous in-house testing, ensuring compliance, reliability, and long-term performance.
