túlfeszültséget

Túlfeszültség refers to a voltage level that exceeds the normal or rated operating voltage of an electrical system or component. This can occur due to various factors, including lightning strikes, switching operations in power grids, electrostatic discharge, or faults within the electrical system. Sustained overvoltage can cause significant damage to electrical equipment, leading to overheating, insulation breakdown, and premature failure. In sensitive electronic devices, even short-duration overvoltages can corrupt data or render the device inoperable.

To protect against the damaging effects of túlfeszültség, various protective measures are employed. Surge protectors, also known as transient voltage surge suppressors (TVSS), are commonly used in residential and commercial settings to divert excess voltage away from connected appliances. In industrial environments and power transmission systems, more robust surge arresters and lightning protection systems are implemented. These devices are designed to safely conduct the high energy of a surge to the ground, thereby shielding the protected equipment. Regular inspection and maintenance of electrical systems are also crucial to identify potential causes of overvoltage and ensure protective devices are functioning correctly.
