This letter shows that the H Delta matrix can be used for redundancy and observability analysis of metering systems composed of PMU measurements and conventional measurements (power and voltage magnitude measurements). The H Delta matrix is obtained via triangular factorization of the Jacobian matrix. Observability analysis and restoration is carried out during the triangular factorization of the Jacobian matrix, and the redundancy analysis is made exploring the H Delta matrix structure. As a consequence, the H Delta matrix can be used for metering system planning considering conventional and PMU measurements. These features of the H Delta matrix will be outlined and illustrated by numerical examples.
