A Heuristic Approach to Conformity Assessment by Clamp-On Testing of a Multi-Rod Earthing System

The paper presents an approach to conformity assessment of a multi-rod earthing system based on the experience of testing of several multi-rod earth fields using the clamp-on testing method. The test results are compared with the results obtained by an alternative method. A multiplier for reduction of the results of the clamp-on method is proposed.
