Description

DIGITAL EARTHING MEASURING EARTHED SOCKET AND GROUP SOCKET SYSTEMS

KNOWN TYPE OF TECHNIQUE;

Earth ground measurement methods have been applied for many years and the basis and application methods are based on scientific logic. Today, these methods can be applied scientifically to industry and all branches of industry and if the conditions in all parameters are fulfilled completely, accurate and scientific results can be obtained.

On the other hand, the rapid development of technology, the constantly changing risks in factories and workplaces, the number of electrical and electronic devices in the living areas where people and households live (hotels, guesthouses, dormitories, holiday villages, office offices, etc.) are constantly increasing increasing rate, continuously changing and developing organizations, constantly changing laws and regulations, occupational safety specifications and requirements, difficulties encountered in practice, constantly increasing production costs, developing and changing perspectives to ensure human safety, the grounding method used in the current situation required to be renewed.

The Earthing Measurement Method applied in the current situation is concluded by measuring the grounding and insulation resistance of the plant and each machine once a year and preparing a report as a result of the measurement results and submitting this report to the measuring company. In this report, it is determined whether the grounding resistance of the plant is within legal limits and recommendations are made to the operational authority. On the other hand, it is determined whether the grounding of each machine, which is an integral part of this report, exists or not, and if a negative situation is encountered at the end of the process, it is ensured that the enterprise is informed about this situation and the missing grounding cables are brought into compliance with the law and measures are taken.

On the other hand, it is legally mandatory to connect the Residual Current Relay of 30 mA against electric shock and 300 mA against Fire Protection to the main fuse boards of all buildings, houses and businesses and industrial organizations.

Grounding measurements are very limited and in very low rates in the houses and other living areas where people live (hotels, guesthouses, dormitories, holiday villages, office offices, etc.) and they are far from protecting people against electrical hazards. Although it is obligatory to perform Risk Analysis for Apartment Buildings in accordance with the Occupational Health and Safety Law No. 6331 issued as a result of the intensive efforts of the Ministry of Labor and Social Security, the applications reached in homes in terms of grounding measurement are far from necessary. Although most of the buildings built before the earthquake regulations have earthing installations completely absent or not, their operability is negotiable.

Although legal grounding measurement methods appear to be scientifically sufficient and reliable, this is not the case in the real sense. In our country, most of the companies operating in both production and service sectors have significant economic and labor problems and these problems are supported by state aids and grants ways are overcome. However, all these supports are not sufficient for each enterprise. Especially in terms of taking precautions in the field of occupational safety, enterprises in our country suffer from a lot and cannot allocate sufficient budget for occupational safety. This endangers the lives of people working in the enterprise. The measurement of grounding and insulation resistance is only one of these conditions, and it is of vital importance that it is an uninformed structure and an insidious danger, often resulting in death.

Although grounding resistance is measured according to rules and regulations, grounding measurement should be done once a year, if the grounding cable inside the machine is accidentally disconnected, accidental tearing off, damage of grounding cable during maintenance and repair of the machine, corrosion of grounding socket due to excessive moisture, incorrectly and improperly replacing the grounding wire, losing the conductivity of the grounding wire during painting of the machine, damaging the electrical installation during the year, stealing the grounding rod or dislodging the grounding rod, although grounding measurements have been successfully applied, , weaknesses are formed after the measurement.

For the reasons described above, people or businesses seem to be right to feel safe because they have taken measurements, but because they are not aware of the real danger, in the event of any leakage, people pay the cost of these errors by getting killed by electric current or seriously injured and this situation is undesirable and the most unfavorable situation.

On the other hand, the leakage current relays required for each operation are 30 mA (Electric Shock) and 300 mA (Fire Protection) which cannot be practically applied by most enterprises, although most of them are mandatory in terms of laws and regulations, most of the enterprises cannot install it on the main panel and The main reason why 30 mA and 300 mA residual current relays cannot be used for enterprises is the most important reason for the fact that most of the enterprises have old electrical installations, their welding machines or other electrical devices have poor insulation renewal and can not take measures as we can say. In this case, when a possible electrical leakage occurs, people pay for it with their lives and face a very grave and sad picture. All citizens who are killed or seriously injured in this way fall into very difficult situations, both morally and financially.

On the other hand, most businesses that do not have a grounding installation use the neutral line as a grounding line, water pipe and so on. hopes for benefits and benefits from fixtures. This practice, which is extremely wrong, continues to be one of the bleeding problems of our country.

For any reason, the fact that grounding measurements cannot be made in a timely manner and that the leakage current relays cannot be used due to economic and infrastructure problems should not cause a person to die due to electric shock. Man is the most valuable asset and treasure living on Earth. It has become inevitable that companies, homes and businesses can see the risks of electric shock and keep up to date in terms of insidious and fatal consequences that have a significant share in occupational accidents. Electric shock is one of the most important sources of danger that must be kept under control On the other hand, the situation is not good in terms of grounding in the houses and other living spaces. The grounding points of the sockets used in households are often corroded and it is not clear whether they call the grounding metal coming from the socket. Users do not realize this negativity and think that the grounding system is working. However, this is not the truth. The grounding system is a very sensitive system and must be operated with a maintenance method. Corrosions on the sockets and the entire system significantly affect the operation of the grounding system and are far from performing the expected performance when needed.

For reasons explained in detail above, whether the grounding system works in the current situation, whether it exists, how much it will work when needed, if people cannot understand when the grounding system is working and cannot take precautions accordingly, the process can be performed according to digital and scientific values the inability to control and find the opportunity to do so are the weakest points of the current system.

However, if it is possible to measure earthing instantaneously in the current system, people will find solutions to the problem caused by grounding weakness and protect themselves against electric shock. The existing system does not allow this

• Protection ground

• Business grounding

• Transformer secondary winding resistors
