Individual grounding resistance measurement

The measurement of grounding resistance for individual grounding systems is a crucial testing procedure aimed at evaluating the effectiveness and safety of grounding systems. In this article, we will provide a detailed explanation of what this measurement is, why it is so important, and who is required to perform it in Hungary. 

What is Grounding Resistance Measurement for Individual Grounding Systems?

Grounding resistance measurement for individual grounding systems is a technical test that determines the resistance of a grounding system. The purpose of grounding is to safely divert fault currents from electrical equipment into the ground, thereby preventing electrical accidents and equipment failures. During the measurement, it is checked whether the grounding system is capable of performing this task effectively.

The measurement involves determining the resistance between the grounding electrode and the surrounding soil. The ideal value is low, indicating that the system can efficiently conduct current. If the resistance is too high, the grounding is inadequate, posing a serious safety risk.

Why is Grounding Resistance Measurement for Individual Grounding Systems Important?

1. Safety Considerations: Proper grounding is essential for preventing electrical accidents, such as electric shocks or fires. The measurement helps identify faults that could endanger human lives and property safety.

2. Equipment Protection: Adequate grounding contributes to the long lifespan and reliable operation of electrical equipment. Faulty grounding can increase the risk of equipment failure.

3. Legal Obligations: In Hungary, grounding inspections are mandatory in many cases, and failure to comply can result in legal consequences.

Who is Required to Perform Grounding Resistance Measurement in Hungary?

Grounding resistance measurement for individual grounding systems is mandatory in the following cases:

1. Newly Constructed Buildings: For all new buildings where electrical equipment is installed, the grounding system must be inspected.

2. Commissioning of Facilities: Grounding inspection is mandatory before the commissioning of electrical installations.

3. Regular Inspections: Existing buildings also require periodic inspections of the grounding system to ensure continuous safety. The frequency of inspections is determined by relevant regulations.

4. Industrial Facilities: In industrial facilities where high-power equipment is used, grounding inspection is particularly important.

5. Residential and Public Buildings: Grounding inspection is also mandatory for residential buildings, offices, schools, hospitals, and other public buildings.

Conclusion

Grounding resistance measurement for individual grounding systems is not only a legal obligation but also a fundamental safety measure. In Hungary, grounding system inspections are mandatory in many cases to prevent electrical accidents and ensure the reliable operation of equipment. By performing these measurements, we not only comply with legal requirements but also contribute to creating a safer living and working environment.
