Grounding Measurement

The reaction of the soil when the electric current passes is called soil resistance. Grounding measurement is a form of measurement using the ground resistance tester to measure this resistance. In electrical installations, the resistance on the conductors carrying electrical current or between the conductors and the earth is the insulation resistance. The deterioration of the conductors over time leads to short circuit or leakage. This situation is dangerous for human health. In order to avoid such a situation, it is absolutely necessary to check the insulation before energizing the installation.

It is necessary to use a grounding measuring device to make grounding measurements. With these devices, the insulation resistance of the soil is measured. These devices are called earth leakage measuring devices. With these specially manufactured devices, it is determined whether the grounding installation is sufficient or even if there is a leak.

Grounding measurements should be carried out by technically qualified persons with electrical engineering training and with a grounding certificate.

Soil is a weak conductor than copper and similar conductors, which are the most commonly used conductors. However, the larger the soil area, the lower the resistance, and the soil can become a good conductor. Therefore, there must be a resistance between the conductors in the system and the ground. The lower the ground resistance, the lower the ground resistance.

Importance of Grounding Measurement

Occupational Health and Safety Regulation published in 2003, describes the measures to be taken to improve health and safety conditions for employees in the workplace. For this purpose, the regulation includes general principles and principles on the following three main issues:

  • Prevention of occupational risks, protection of health and safety of employees and elimination of possible risk and accident factors
  • Training and informing of employees and their representatives about occupational health and safety, obtaining their opinions and ensuring their participation in this matter
  • Working conditions of employees who need special protection due to age, gender and special circumstances

Within this framework, employers must protect the health and safety of employees in all matters related to the work performed. The fact that employers receive services from experts or organizations outside the workplace does not remove their responsibilities in this respect. In addition, employees have obligations in terms of occupational health and safety, but these obligations do not remove the responsibility of the employer.

Grounding systems are very important in terms of providing security in production facilities, buildings and factories. If there is no ground electrode in the system, the safety of the workers is in danger and machinery and equipment are likely to be damaged. Employees who come into contact with an ungrounded machine or equipment may receive fault currents from the system and may result in death or disability due to the power of these currents. In order to ensure this safety, grounding measurements must be performed regularly.

Earth leakage measuring devices, known as Meger in the market, are used to measure the adequacy of the earthing installation or the leaks in the existing installed earthing installation. Since the name of the company that develops these devices is Meger, the earthing devices are also called Meger. The Meger device generates and delivers a certain amount of voltage to the line and makes measurements with this method.

Electricity has no jokes. Even the slightest carelessness can cause serious hazards. For this reason, workplace safety must be ensured by professional teams. If there is leakage at the points where the power lines are located, this situation should be determined and precautions should be taken in a short time.
