Earth voltage measurement
WebMay 22, 2024 · The resistance of concern is designated r1. A series of three two-point measurements are taken, as the resistance between the electrode under test and each of two auxiliary electrodes, designated r2 and r3. The three measurements then would be r12 = r1 + r2, etc. The resistance of the test rod can then be calculated as. r1 = [r12 – r23 + … WebJun 18, 2024 · Voltage measurements are relative measurements. That is, a voltage measurement must be compared to another point in the circuit. If it is not, the measurement is meaningless. The ground reference point is often, but not always—more on this later—represented by a standard ground symbol. See Figure 1. Figure 1. …
