Leakage currents may occur in electrically driven machines and equipment due to conditions of use, or due to incorrect connections or due to wear and tear in the connections over time. In general, a healthy and correctly installed grounding system provides leakage currents to the ground and prevents potential hazards to human life and property safety. However, in some cases, for example, if the earth line shows high resistance or if the cable connected to the earth line comes into contact with another location, the leakage current cannot be removed from the electrical installation. That is where risk exists.

The magnitude of the risk is directly proportional to the value of the leakage current. As soon as the leakage current exceeds 30 mA, the magnitude of the hazard is large. 30 mA is the limit value for which people will be harmed. All electrical and electronic devices can generate leakage currents. Therefore, necessary precautions should be taken from the beginning. The main method used in this regard is to use a leakage current relay. Residual current relays are much more effective than the fuse used in electrical systems. Thanks to this relay, when the leakage current value in the installation exceeds the value of 30 mA, electricity is cut off. However, the smallest value in insurance is above this figure. If the leakage current cannot be discharged to the earth line due to a problem in the installation, the residual current relay disconnects the main connection and prevents potential hazards.

According to existing standards The leakage current relays are manufactured between 30 mA and 300 mA. The operating principle of the relays is based on the current difference between phase and neutral in the installation.

Leakage current tests are also carried out among authorized electrical laboratories. our organization in the scope of LVD testingConducts LVD leakage current tests in accordance with the relevant regulations, standards and test methods published by domestic and foreign organizations. These tests are available on the one hand leakage current relays are tested while detecting leakage currents on electrical circuits.

In the meantime, our organization, ÖSAS Accreditation Agency, It is accredited according to TS EN ISO / IEC 17025 standard and the tests, measurement, analysis, inspection and inspection procedures and reports are accepted as valid in private and official audits.
