- Time-Division Multiplication principle

 

Watt Transducers WAT 95

          Watt Transducers WAT 95 are used to convert single or three phaseunbalance load active power into a proportional load independent DC. Output.Based fully on electronic Time-Division Multiplication measuring principle,the true power of a network with any power factor range are linearly produced by Watt Transducer output.

Equation to calculated measuring range
Measuring range = Calibration watt x PT ratio x CT ratio
Example 3phase,3wire, PT 220V/110V, CT 250/5A, Calibration watt = 1000W
Measuring range = 1000 x 220/110 x 250/5 = 100 KW.
