Voltage Transformers
A voltage transformer (Potential Transformer or Voltage Transformer) is a small voltage transformer used to convert high voltages. It is a low voltage used with a voltmeter, wattmeter, and kilowatt meter. The output power rating is expressed in volt-amperes (VA). The voltage rating indicates the voltage of the primary and secondary coils, such as 1500/100 volts, 4800/120 volts, 22000/. 110 volts
