Ground system testing is a core component of ensuring property safety. Maintaining solid electrical function is critical, but ensuring the efficiency and safety of that electrical system reduces risks to human life and property.
Now let’s dive into the importance of ground system testing and how you can refurbish as needed.
What Is an Electrical Grounding System?
Let’s start with the basics: What is an electrical grounding system? In short, it ensures that excess electrical energy moves back into the ground without damaging anything, including people. It is like an exit or a place for extra electricity to pass through the ground, minimizing risks.
To clarify further, electrical balance occurs by transporting positive charges carried through the neutral wiring and negative charges through the black wiring circulating into the ground. There are various reasons why this balance could be inaccurate. If that happens, a short circuit will occur.
If a short circuit happens, it can cause the flow of the current to go where it should not, including through electronics or any metal exteriors, whether in a home or an industrial building. This can lead to electrocution but also cause devastating electrical fires.
You need a grounding system but must also test and maintain it.
What Is Electrical Ground Testing?
Ground testing is the process of ensuring safety for any type of electrical system. Electrical circuits need a path to the ground that eliminates or minimizes resistance. In situations where something accidentally gets in the way of a circuit, that path prevents injuries and damage to the property.
Ground testing aims to locate this path to the ground and ensure that it meets all related safety requirements.
Ground testing typically occurs at one or more times:
- When the building goes up
- When you know that there are problems with the system
- Routinely to ensure the system continues to operate as desired and expected
Two Types of Ground System Testing
There are two main methods of ground system testing. Those methods include:
1. 3 Point Test
This test requires complete isolation from the power utility and the removal of any neutral or other ground connections extending outside of the grounding system. It is most commonly done for large grounding systems, but it can also be helpful for small electrodes. This method is referred to as fall-of-potential.
2. Induced Frequency
Also known as the clamp-on method, this method is performed while the power is on and functional. It requires the utility to connect to the grounding system under a test.
The test is typically best suited for small electrodes because it uses frequencies in the kilohertz range. These frequencies see long conducts as inductive chokes, which means they do not reflect the 60 Hz resistance of the entire grounding system.
Ground testing is an essential starting point. When testing reveals concerns, a certified electrical engineer becomes your go-to professional to help you make any necessary changes to your grounding.
There are various ways to test grounding and make changes. Regardless of the method, ensuring the system provides a quick and unimpeded path to the ground is critically important. If that cannot be done and testing shows that it is not happening, it is time to consider some of the allowable changes.
The Benefits of Refurbishing Ground Assemblies
Repairs can be made once a problem with the grounding system is determined. One option is, of course, to completely remove and replace the ground assemblies. While this would improve the outcome, it tends to be unnecessary and much more expensive than other solutions.
Therefore, it is often beneficial for organizations to consider testing and refurbishing instead. This is a cost-benefit because it does not require the use of as many or as much manpower or material. It also ensures that full compliance and safety requirements are met.
The core advantages that come from refurbishing ground assemblies include:
- Significant cost savings.
- Reduced environmental impact
- Faster development and solutions
Refurbishing offers numerous benefits and tends to be the ideal solution, but that is only applicable in situations where you hire the right team to handle the work. Ensuring it is done correctly is critical to effectively refurbishing any grounding system.
