This instrument is used to convert the Tap Position of ON-LOAD TAP CHANGER employed in Transformer, into corresponding DC Current Signal Outputs. THIS SYSTEM IS ELECTRICALLY ISOLATED FROM INPUT POWER SUPPLY. Purely a transmitter, this can be used where there is no requirement of indication or in conjunction with a separate
indicator. With the availability of 4-20 mA DC signal output, the instruments can be used to integrate TAP position readings to scada systems.
