Automatic Voltage Regulator (AVR)
The On Load Tap Changer, automatic voltage regulator (AVR) is used to compensate the voltage drop in the electrical network‚ so that customers at the line end receive the same average voltage value as those closer to the source.
The voltage value reduction affects the operational quality of the rotating machines & increases the losses due to the high current drawn due to the voltage reduction. It also affects the quality of the illuminating system

Automatic Voltage Regulator (AVR) with on Load Tap changer
Automatic Voltage Regulator (AVR) with rating up to 600 A & 17 tapping positions
The AVR is flange mounted (ON TANK) or (IN TANK) type according to the rating of the transformer and a remote tap changer control cubicle (RTCC), Also, boosters to give a small boost to distribution cable for compensating the voltage drop.
You can get the same advantage of the Variac.

- Range
- Applications
- Advantages
- Up to 600 A, up to 33 KV and more than 17 taping positions on request
- Use it as a safely starting machines such as induction motors and synchronous motors
- Also, boosters to give a small boost to distribution cable for compensating the voltage drop
- you can get the same advantage of the Variac
- Increased KVA rating for a given size and mass
- Less amount of copper
- Due to the smaller size, the cost is less compared to a two – winding transformer
- The resistance and reactance are less compared to a two – winding transformer and hence it has superior voltage regulation
- The Volt-ampere rating is more compared to a two – winding transformer
- It is possible to get a smooth and continuous variation of voltage
