HT Transformer with inbuilt AVR

HT Transformer with Inbuilt AVR

MS Engineering is a leading manufacturer of HT Transformer with Inbuilt AVR (Automatic Voltage Regulator), offering an advanced power conditioning solution for industries requiring stable high-voltage power supply. This innovative system combines a High Tension Automatic Voltage Regulator (HT AVR) with a high-quality Distribution Transformer into a single compact unit, ensuring accurate voltage regulation, improved efficiency, and significant savings in installation cost and space.


The incoming 11KV or 33KV grid supply first passes through the integrated HT Automatic Voltage Regulator, which stabilizes the voltage with an accuracy of ±1%. The regulated HT voltage is then supplied to the Distribution Transformer, delivering a highly stable Low Tension (LT) output with the same voltage accuracy. This advanced technology ensures maximum equipment protection and uninterrupted industrial operations.


Unlike conventional installations using separate HT stabilizers and transformers, the integrated design reduces installation cost, minimizes maintenance, saves valuable floor space, and improves transformer utilization up to 100% by maintaining rated input voltage under varying grid conditions.





Advanced HT AVR Technology

MS Engineering HT Transformers with Built-In AVR are engineered using advanced voltage regulation technology that automatically compensates high-voltage fluctuations before power reaches the transformer. This ensures consistent voltage, improved power quality, and reliable protection for industrial electrical systems.


The integrated HT AVR is capable of stabilizing low input voltage ranges from 5KV to 12KV in transformer ratings up to 5000 KVA, making it an ideal solution where LT stabilizers or conventional OLTC systems are impractical due to high current requirements or limited correction range.


Compact Integrated Design

Combines HT Automatic Voltage Regulator and Distribution Transformer into one compact solution, reducing installation space and project cost.

±1% Voltage Accuracy

Maintains highly accurate output voltage even during severe HT supply fluctuations, ensuring maximum equipment safety.

High Transformer Utilization

Supplies rated voltage to the transformer, allowing maximum utilization of transformer capacity while reducing overload conditions caused by voltage drops.

Low Maintenance Operation

Heavy-duty construction ensures reliable, maintenance-free performance with long operational life in demanding industrial environments.
