Ensuring safety in electrical installations is not possible solely through correct wiring or the use of quality materials.
There are two fundamental elements that protect the continuity of the system and human life: earthing (grounding) and surge protection systems.
When these two components work together, electrical accidents and equipment damage are largely prevented.
In this article, we will examine what earthing and surge protection systems are, how they work, and why they are complementary structures.
🔹 What is Earthing?
Earthing is a system that ensures leakage currents that may occur in electrical installations are safely transmitted to the ground.
The aim is to protect people and equipment from possible electric shocks or high potential differences.
An earthing system typically consists of conductive rods (electrodes) buried in the ground and conductive lines connected to these electrodes.
In the event of a fault, the leakage current flows through these lines to the ground, which is the path of least resistance, and the danger is eliminated.
An earthing system that is not properly installed or periodically tested can pose hidden risks in electrical installations.
Therefore, it is a requirement for businesses to have annual earthing measurements carried out, in accordance with both the Occupational Health and Safety Regulation and the Electrical Internal Installations Regulation.
🔹 What is a Surge Protector?
A surge protector is a device that protects an electrical system against sudden voltage increases.
High voltage surges, especially those caused by lightning strikes or grid fluctuations, can cause serious damage to devices.
The surge protector ensures system safety by diverting this sudden voltage to the ground.
In short:
- When lightning or a sudden voltage surge occurs → The surge protector activates.
- It transfers the voltage to the ground → Electronic devices and the system are not damaged.
- After the danger passes → It returns to normal operation.
Surge protectors are generally used in panel inputs, transformer centers, energy monitoring systems, and communication lines.
🔹 The Connection Between Earthing and Surge Protection
The healthier the earthing system, the more effectively the surge protector works.
This is because the primary function of the surge protector is to transfer excess voltage to the earth line.
If the earthing resistance is high, the energy on the surge protector cannot discharge quickly enough, and system protection is weakened.
Therefore, both systems must be designed together and tested regularly.
Let's explain with an example:
In regions with a high risk of lightning, such as Antalya, the use of surge protectors is critically important, especially in industrial facilities or hotel complexes.
However, no matter how powerful the surge protection system is, if the earthing measurement is insufficient, the lightning current cannot be effectively discharged.
As a result, devices can still be damaged.
Therefore, for effective protection, the following rule applies:
🔹 Importance of Periodic Measurement and Maintenance
Earthing and surge protection systems should not be forgotten after installation.
Over time, earth resistance changes, connections loosen, or electrodes oxidize.
Similarly, surge protectors lose their effectiveness after a certain number of strikes.
Therefore, the following procedures should be carried out at least once a year:
- Earthing resistance measurement
- Visual and electrical inspection of surge protectors
- Tightness test of connection points
- Updating device calibrations
The advisory notes included in the reports prepared as a result of these measurements actually represent mandatory criteria to be implemented by the employer.
These warnings must be taken into account for the safety of the facility.
