Abstract :
The authors present a method of measuring the wet resistivity of rock used in covering substations and derive an approximate formula relating this resistivity to the resistivity of the water used in wetting the rock. They also propose a standard resistivity of rain water of 100 ohm meters and a standard method of making the test
