Soil Continuity Tests
Continuity test is one of the periodic electrical tests that must be performed within the scope of occupational health and safety law. One of the points that makes the continuity measurement important is that the continuity of the ground line is tested. By measuring the continuity in the ground line, we control the continuity between the electrical conductors and determine the points where continuity is ensured in the electrical indoor installation. Therefore, conducting a conductor continuity test with a correct approach is important for periodic control report results.
The earth continuity test is performed between the PE (protection) conductor and the accessible metal parts. The purpose here is to ensure the safety of the person or operator using the product in case of any possible electrical leakage. 50Hz-10A current injection for at least 10 seconds. should be applied and the measured resistance value should be less than 0.1 Ohm. For this situation, it is desired that there is a transmission at the farthest distance the earth conductor to this conductor in an electrical panel or a machine operating with electricity. In addition, it is desired that this transmission continues continuously. In case of a possible electrical leakage, whether on the cover of the panel or the body of the machine, this leakage is required to flow the ground conductor for the safety of the user or operator. For this, a constant current of 10 amperes is given between the earth conductor and the farthest distance, and the voltage here is measured. In the light of the measured data, the resistance is calculated according to ohm´s law. Here the resistance must be less than 0.1 ohm.
The main idea of ??grounding is to protect human life, to protect operating elements and other goods against damages that may be caused by electricity in case of any fault. Before a newly built or changed product or business is put into use, it must be observed qualitatively (by eye) and quantitatively (experimentally and measurement) during the assembly and construction phase.
Soil continuity tests are carried out within the framework of legal regulations covering this subject. These legal regulations are:
-Groundings Regulation in Electrical Facilities
-Electrical High Current Facilities Regulation
-Electrical Indoor Facilities Regulation
-Electrical continuity in businesses means the protection of grounding systems against chemical, mechanical and electrochemical deterioration. These tests are carried out between the protective conductor and accessible metal parts. The purpose of these tests is to ensure the safety of people using the electrical device in case of an electrical leakage. In fact, the basis of grounding works is to ensure human health and property safety of the enterprise. In case of any malfunction or error, the idea of ??protecting the damages of electricity is essential. Before a newly purchased or replaced device is put into service, tests and measurements must be made during the assembly and installation phase.
Among the many electrical tests, soil continuity tests are also carried out in authorized laboratories. Our organization also carries out LVD soil continuity tests within the scope of LVD test studies in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations. Here are a few standards that are taken into account when performing these tests:
TS HD 60364-4-43 Electrical installation in buildings - Part 4: Safety protection - Group 43: Protection against overcurrent
TS HD 60364-5-54 Building electrical installations - Part 5: Selection and installation of electrical devices - Part 54: Grounding arrangements and image protective conductors
