ABSTRACT:
A method for the nondestructive testing of voltage limiting blocks includes the steps of providing several discrete electrical contacts across the block, sequentially applying to each of the contacts a voltage to determine the corresponding current and utilizing the current and voltage values to determine constants related to the microstructure of that particular location. The constants can then be utilized to derive a contour map which will be indicative of a hot spot in such block as determined by a maxima of the contour map.
