This paper presents a procedure to identify the on/off statuses of breakers at substations throughout a power network. It is intended as a structural data preprocessor prior to running a state estimator. The procedure relies on a dc model of power lines and busbars, and requires the solution of a well-behaved mixed-integer quadratic programming problem. The proposed procedure is illustrated using a simple example and a realistic case study.
