Seisklüliti

Seisklüliti is an Estonian term that translates to "earth switch" or "grounding switch" in English. It refers to a type of electrical switch used in power systems for earthing or grounding purposes. These switches are designed to connect a specific part of an electrical circuit or equipment to the earth.

The primary function of a seisklüliti is to provide a safe path for fault currents to flow to the ground. This is crucial for protecting both personnel and equipment from damage during electrical faults, such as short circuits or insulation failures. By earthing the system, any excessive voltage buildup is safely dissipated into the ground, preventing dangerous voltage levels from appearing on conductive parts.

Seisklülitid are typically operated manually, though in some advanced systems, they might be incorporated into automated protection schemes. They are commonly found in substations, industrial facilities, and other high-voltage installations. The design of a seisklüliti ensures it can handle the potentially high currents associated with faults for a short duration until protective devices like circuit breakers can isolate the fault. They are a fundamental component of electrical safety and grounding systems in many countries, including Estonia.
