A grounding rod serves as an essential component in electrical systems as it provides an alternate route that excess current can utilize to be dissipated into the ground. However grounding rods have a limited lifespan and once they wear out, they can be especially hazardous to an electrical system as a whole enticing the very questions that define Can An Earth Rod Go Bad? The good news however is that there are key indicators that outline the answer to this question, and can provide clarity to when the earth rod needs to be replaced or maintained.
- Check the Electrical Resistance
Knowing the electrical resistance of an earth rod is imperative as it allows a user to determine whether or not the grounding rod is fully functional. It is commonly agreed that an electrical resistance below the mark of 25 ohms is considered to be ideal for a ground rod, while values exceeding 25 ohms suggest poor functionality. There are several factors that contribute to the latter, for instance a copper grounding rod which when being utilized in arid soils may not fully reach its efficient potential. It is also worth noting that ground resistance testers can also be used to match the resistance values and to a monitorputation’s electric field.
Using copper-clad steel rods can prove to be an even bigger hassle since the insulation can start coating once it begins to wear off resulting in rust and corrosion forming at the bottom, which not only increases the amount of resistance but causes issues with grounding as well.
In case you are consistently observing high resistance levels this may indicate that you are needed to replace your earth rod and can opt for a material that is better suited, regularly pure copper rods can resist a large amount of corrosion as compared to others available within the market.
- Inspect for Corrosion or Physical Damage
The combination of physical damage and corrosion is enough for you to understand that your rods are doing their job of grounding. Over a period g that can be a long time the elements of nature apply wear and tear to galvanized ground rods and other copper clad steel rods instead.
The metal underneath steel rods can rust due to the exposure of environmental factors resulting in the galvanizing coating to wear off. This is essential for steel rods since it protects them from rust but can wear off due to high amounts of moisture, extremely cold temperatures or heavy amounts of salt.
Essentially copper clad steel rods are protected by a layer of copper that acts as a shield against rust but if the layer cracks or erodes the steel loses protective layer and lowers the performance of the gounding system.
Begin with a visual assessment of the earth rods for any traces of corrosion. When inspecting, if you come across any discoloration, rust, or any areas that have been worn out, then this earth rod is not in good shape. A wire brush or other tools may also be useful in clearing any corrosion. If there is considerable corrosion damage, replacing the rod will be the best idea.
- Monitor the Trends of the Effectiveness of the Grounding System
The failure of a ground rod may cause your electrical system to malfunction. A bad ground connection may result in frequent electrical spikes, tripped breakers or faulty electrical equipment. The poor working may be attributed to the old age of the grounding rod, which renders it incapable of providing a serviceable return route for electrical currents to flow back into the ground.
An essential part of safeguarding your electrical systems is through the use of an earth rod. It aids in the stabilization of electrical voltage while also preventing nefarious electrical consequences. The absence of sufficient electrical grounding increases the chance of electrical system damage during voltage surges. Hence in case there are any strange changes in the electric circuitry equipments, check the earth rod and determine its level of resistance.
- Get to Know Grounding Rod Changes
Over the course of time, moisture variation can lead the soil around the grounding rod to shift making it unstable. In such conditions, the grounding rod tilts or moves up and does not get sufficient contact with the ground making the performance of the grounding system inefficient.
Copper clad steel rods are quite vulnerable to damage especially when the protective copper coating wears off but on the other hand ultrapure copper rods are a lot more resilient.
To prevent this, examine your earth rod frequently, particularly when there are abrupt weather changes. Additionally, if the soil gets eroded around it and exposes the upper part of the ground, then realigning the rod can greatly improve the systems performance.
