L T Transformer Voltage Stabilizer Brand G TB Power 100 KVA to 2500 KVA Input Voltage 300-480 V Phase Three Phase Automation Grade Automatic frequency 50 hz to 60 hz output voltage 415V GTB 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. We have developed state of the art technology HT Automatic voltage regulator that operates on load, sleeplessly & gives stabilized voltage on the HT side. The fluctuating voltage from Grid is initially controlled by the HT AVR and then fed to the transformer resulting in the constant H.T. Output within +/- 1% accuracy and the biggest advantage being its robust design; Lesser losses & more efficiency make the distribution transformer to utilize up to 100% capacity. RANGE: Upto 15 MVA 11 & 33 kV Class.
