FAQ

 



Q： Why is earth ground testing important?



A： Earth ground testing is vital to mitigate risks linked to insufficient grounding, preventing equipment failure and safety hazards. A robust grounding system establishes a secure pathway for current, crucial events like lightning strikes or overvoltages. This not only safeguards equipment by maintaining stable voltages but also ensures the safety of individuals working with or around electrical infrastructure. In essence, proper earth ground testing is foundational for both equipment reliability and personnel safety in diverse electrical scenarios.



 



Q：



A： A longer grounding rod, especially when driven deeper into the earth, significantly reduces earthing resistance. This relationship underscores the importance of optimal rod length and depth for efficient grounding, ensuring enhanced safety and equipment protection.



 



Q： Is a high earth resistance very good for earthing?



A： No, high earth resistance is not desirable for earthing. Low earth resistance is crucial for effective grounding, as it ensures efficient dissipation of fault currents into the ground, reducing the risk of electric shock and fire hazards. High resistance can lead to increased voltage on exposed metal parts, posing safety risks and compromising the performance of electrical systems.
