Abstract
The lattice diagram has been widely recognized and adopted to analyze the voltage surges produced at a particular location in an electrical system. These transient surges are caused by traveling waves induced by lightning strikes or switching operations. The lattice diagram can be used effectively, but the required computations are tedious. A simplified approach for computing induced voltage surges based on mathematical derivation is presented. This method permits a quick evaluation of both an initial and crest surge magnitude and wave shape based on a given incoming surge and the surge impedances of the electrical elements involved. Sample calculations from the lattice diagram and the proposed quick evaluation are compared.<>
