When should ground testing be performed?

Ground testing should be performed monthly, especially after weather events, because this ensures that the grounding system is functioning correctly and providing the necessary safety measures to protect both personnel and equipment. Weather events, such as heavy rain, storms, or flooding, can affect the integrity of grounding systems by altering soil conductivity or damaging grounding connections. Regular testing helps identify any issues that may arise due to these environmental factors, allowing for timely repairs or adjustments.

Performing ground tests only before new installations or only after grounding equipment has been installed does not account for ongoing factors that could impact the system's effectiveness over time. Annual testing may not be sufficient in regions prone to extreme weather variations, as critical changes can occur that need to be monitored more frequently to ensure safety and compliance with regulations. Regular monthly testing provides a proactive approach to maintaining a reliable grounding system.
