Transformer Tap Position transducer
Input Resistance output (DC) single or dual
Accuracy 0.5%

Operations

It is a precision grade transducer is used for galvanically isolated measurement of Transformed Tap or Resistance (2 Wire or 3 Wire). It measures the value of resistance on tap position changers, typically used on high voltage transformers. Each position on the selector has an equal value of resistance so that as the tap position is increased or decreased the value of resistance increases or decrease respectively. The input is in the form of Resistance and provides a Stable, Ripple- Free and Optically Isolated DC load independent output in the form of current or voltage. The transducer is fully solid state. Use of latest circuit techniques and quality components ensure reliable operation over long period.
