Since the grounding resistance tester is used to test the grounding resistance of the circuit,Earth Resistance Tester it plays a huge role in maintaining the safety of the circuit. Therefore,Earth Resistance Tester in its operation, the staff must standardize the operation to ensure that it will not have problems. So what aspects should we pay attention to in use?

Reduce the grounding resistance of power line towers. The advantage of this is that it can increase the lightning resistance level of the line, reduce lightning damage accidents,Earth Resistance Tester reduce the touch voltage and step voltage near the tower, and avoid human and animal electric shock accidents. Therefore,Earth Resistance Tester the grounding resistance of the tower is an important data. All aspects of design, construction,Earth Resistance Tester and operation must be taken seriously, and its actual value must be accurately measured and lower than the specified value. Understand the measuring principle of ground resistance tester. This is used to measure the grounding resistance of any loop system. The instrument itself can generate a power supply potential,Earth Resistance Tester and current can occur in any loop system. Therefore, the measurement principle is simply the Ohm's law of the entire circuit,Earth Resistance Tester which measures Is the loop resistance value of this loop system.

The measurement method must be correct. The grounding resistance tester measures the grounding resistance of the power line towers in a simple way and has a high degree of credibility,Earth Resistance Tester but it can only be used on high-voltage lines with overhead ground lines. During the measurement, only one ground lead can exist in the tower to be tested,Earth Resistance Tester such as each tower The ground net of the feet is not connected. After disconnecting the ground lead wires of the other feet,Earth Resistance Tester use a temporary wire to connect with the lead wires of the measuring feet. Through the analysis of the measurement results,Earth Resistance Tester it can be judged whether the ground net of each tower foot is connected,Earth Resistance Tester and whether there is a danger of bad touch of the ground lead.
