H.T. Automatic Voltage Stabilizers from our premium range are renowned for their outstanding performance and efficiency. The voltage variations received from the electricity authorities are stabilized by these H.T Automatic Voltage Stabilizer. These H.T AVRs also stop the transformer and other electrical equipment from becoming overloaded. Wide voltage variation ranges are continuously monitored and corrected, under a load condition. Helical coils are mounted on a typical laminated core of H.T. Automatic Servo Voltage Stabilizers. The length of the coil track is traversed with carbon rollers that have been assembled on a carrier board made of fiberglass. These H.T stablizers are available in 11 KV and 33 KV Voltage Class.
