Abstract :
A novel topology analysis method is presented to analyze the testability of grounding grids, and creditability is firstly proposed as an important index to evaluate the results. In this method, inaccessible nodes are eliminated by wye-delta transformation, followed by the calculation of testability and creditability index in the reverse direction. Simulation results are provided to prove this method.
