ETAP State Estimation processes telemetry data such as power measurements to obtain an estimate of the magnitudes and phase angles of bus voltages in the actual power systems.

Using these values, the State Estimator examines the data for obvious data errors, determines those portions of the network which have sufficient telemetry to be observable, generates artificial measurements (called "pseudo" and "virtual" measurements) at locations where they are required for observability, and then computes the estimate of the system voltages and the tap positions of tap changing transformers.
