This paper addresses a problem in state estimators for power systems. The issue of non-collocated measurements is studied. The measurement of P+jQ in a line or at a bus is usually accomplished by measuring voltage and current at an appropriate point. A transducer converts the voltage and current measurement to active and reactive power which are transmitted to the state estimator. If the voltage and current measurements are not at the same point in the circuit, that is the measurements are non-collocated, error is introduced. The paper reports a way to correct for non-collocation of measurements.
