Getting to Know Grounding Measuring Instruments: Functions, Uses, and Types in Solar Power Plant Systems

In the world of electricity, the Grounding system is one of the important elements that is often overlooked, even though its role is very crucial in maintaining the safety and reliability of electrical installations, including in the Solar Power Plant (PLTS) system. One of the tools used to ensure that the grounding system is working properly is the Grounding Measuring Instrument or also known as the Grounding Tester.

What is a Grounding Measuring Instrument?

A grounding tester is a device used to measure ground resistance. This value indicates how well the electric current from the system can be channeled into the ground, especially when there is a disturbance such as leakage current or lightning strikes.

This tool is needed to ensure that the grounding system meets applicable safety standards and is able to protect equipment and personnel from electrical risks.

Why is Grounding Important in the Solar Panel System?

In the PLTS system, both on a household and industrial scale, grounding functions as a path for releasing fault current to the ground. A poor grounding system can cause:

• Damage to the inverter and solar panels,
• Disruption of the overall system operation,
• Risk of electric shock,
• Decreased device life.

Therefore, periodic checks using a grounding measuring instrument are highly recommended, especially to maintain the reliability and safety of the Solar Panel system in the long term.

Types of Grounding Measuring Instruments

There are actually two types of electrical grounding measuring instruments, namely the earth tester and the earth clamp. These two grounding testers have different uses. Here is an explanation of the two:

1. Earth Tester

Earth tester is a very useful tool in the process of installing or maintaining a new grounding system. By measuring the ground resistance and identifying areas with high resistance, technicians can take the necessary corrective actions to improve the quality of the grounding and ensure the safety of the system as a whole.

2. Earth Clamp

What about the earth clamp? This grounding measuring tool is a device that functions to measure ground resistance by detecting the current flowing through the grounding system. Consisting of a clamp head that can be installed around the ground conductor, such as a grounding cable or grounding rod, this device can measure the current passing through the ground conductor and calculate the grounding resistance automatically based on the detected current.

By using an earth clamp, we can easily and quickly measure ground resistance without having to physically connect or disconnect the ground conductor. This makes the measurement process more efficient and can be done safely and accurately.
