It guarantees that the grounding path has minimal resistance, . A reliable earth connection is essential for providing a path for fault current to safely dissipate, preventing the risk of electric shock and fire hazards. In practice when PAT testing, measuring the actual resistance of Satisfactory earth continuity and insulation test results indicate that it is safe to proceed to leakage current tests. This makes this process Polarity Test. Therefore this method is also known as the stakeless method of earth testing. It reflects the contact resistance between the exposed parts of electrical equipment and the total grounding terminals of electrical equipment. Where the R value is the resistance of the protective conductor (earth wire) within the supply cable. Repeat the technique for the other windings. This test confirms the continuity between two different ground points of interest verifying that the grounding line can carry operating and fault currents (Figure 2). Expla-nations are given under the presumption that the reader has knowledge about the electrical aspects of elec-trical safety testing. 3 Clamp-On Testing is a simple earth resistance measurement method that does not require additional test electrodes. 05~6kV. g. 2009 operation manual earth continuity tester tos6200 tos6210 Electrical Tests. 2. 001 to The obligation to test earth continuity is separate from and additional to tghe obligation to test EFLI> It\'s also universal; ie every point on every circuit, compared with just the end point on circuits supplying non-RCD sockets.
