Transformer With HT Automatic Voltage Regulator

• The incoming supply from the grid sometimes fluctuates widely and after the installation of standard distribution transformer the customer faces low/high voltage problem on the LT side affecting the rated voltage of the machines, thereby damaging motors and other sophisticated equipment. 
• The standard off-circuit tapping of the transformers can correct limited voltage variations but cannot regulate the voltage while in ‘on load’ condition. 
• These transformers with built-in HT automatic voltage regulators operate on load steplessly and can also be installed either indoors or outdoors.
• The equipment is basically a combination of standard distribution transformer and HT automatic voltage regulator; the incoming fluctuating HT supply is initially stabilised then fed to the transformer and thereby the LT output is maintained within ±1% accuracy.
• The design is robust and needs no regular maintenance.
