We are offering h t automatic voltage stabilizer. Servomax make copper wound, ht avr suitable for indoor outdoor installation, copper wound ht avr system is a revolutionary landmark in the industry when it comes to voltage regulation and stabilization. Even after the installation of standard distribution transformer the problem of low high voltage on the lt loss of a plant. The standard off - circuit tapping of transformers can correct limited voltage variation and cannot regulate the voltage while in ‘on load’ conditions.
