Korkeajännitevälineen

Korkeajännitevälineen is a Finnish term referring to high-voltage equipment. This category encompasses a wide array of devices used in electrical power systems to generate, transmit, distribute, and control electricity at voltages typically exceeding 1,000 volts. The primary purpose of high-voltage equipment is to minimize energy loss during long-distance power transmission and to enable efficient voltage transformation for various applications.

Key examples of korkeajännitevälineet include transformers, which are crucial for stepping up voltage for transmission and stepping down for distribution. Circuit breakers and switches are essential for protecting the system from faults and for isolating sections for maintenance or operation. Insulators, made from materials like porcelain or composite polymers, are vital for preventing electrical current from flowing to unintended paths, such as supporting structures. Surge arresters protect equipment from transient overvoltages caused by lightning or switching operations. High-voltage cables are specifically designed to safely conduct electricity at elevated voltage levels, often featuring robust insulation and shielding. Capacitors and reactors are used for power factor correction and voltage regulation within the grid. The design and maintenance of these devices are critical for the reliable and safe operation of any electrical power network.
