The purpose and function of a Voltage transformer is almost like that of a current transformer except that high voltages are transformed to manageable low voltages to operate metering and protective systems. Generally Voltage Transformer is like a power transformer directly connected to a system line. Separate windings are provided for a metering and protection with different accuracies and voltage factor required for various applications.

DESIGN
Agarwal Industries manufactures the following types of voltage transformers.
1. Single Pole (Neutral Earthed)
2. Double Pole(Line to Line)33KV
3. Three phase (Neutral Floating/Earthed) up to 33KV
On request from users voltage factors varying from 1.2 to 1.9 continuous are offered to suit various system earthing conditions.

PRIMARY and SECONDARY WINDING Modified polyester enamelled copper wires used for winding of primary and secondary. At all stages of winding, care is taken to protect winding to avoid high surge and high voltage stress.
