Example text

11. 1 Purpose The main purpose of a model test is to help predict the probable resistance to true earth of a complex ground electrode or to predict the probable voltage gradient of a complex ground system [B1], [B11], [B13], [B25], which otherwise cannot be calculated accurately. 2 Similarity Criteria and Limitations The work starts by establishing the earth structure to be modeled; the reduced model will then have to obey certain laws [B11]: 1) 2) All the geometrical dimensions of the earth model and of the test electrode should be scaled according to one unique factor µL.

3 Selection of Auxiliary Equipment The following additional equipment may be useful to ease and speed up the measurements. 1 Hammers In normal soils, hand hammers (2 to 4 kg of mass) are satisfactory for driving the rods to depths of 2 m-3 m. The driving force should be axial to the rod in order to avoid undue whipping. A practical type of hammer useful for the prevention of whipping consists of a chuck and sliding hammer (Fig 20). This device has the advantage that the work may be at a level convenient to the individual making the test without using an auxiliary platform.
