In an electrical distribution network, the voltage is typically Stepped-Down from H.T. to L.T. by a normal distribution transformer, but it cannot handle the fluctuating voltage, and it has been discovered that the issue of fluctuating voltage persists at the majority of locations and causes electrical systems to operate improperly most of the time. The H.T. Transformer with In-Built H.T. Automatic Voltage Stabilizer offers comprehensive solutions for voltage fluctuation and stabilization. Essentially, the device is a normal H.T. Distribution Transformer functioning in tandem with an H.T. Automatic Voltage Stabilizer. These are in 11 KV and 33 KV Voltage Class, manufactured upto 8000 kVA.
