Keskijännitteisen

Keskijännitteisen is a Finnish term that translates to "medium voltage" in English. It refers to a range of electrical voltages that are higher than low voltage but lower than high voltage. In electrical power systems, medium voltage is typically used for the distribution of electricity from substations to end-users, such as industrial facilities, commercial buildings, and residential areas.

The specific voltage range considered "medium voltage" can vary slightly depending on the region and the standards being followed. However, it commonly falls between 1 kilovolt (kV) and 36 kV. This voltage level is a compromise between the efficiency of transmitting power at higher voltages and the safety and insulation requirements of lower voltages. Low voltage is generally considered to be below 1 kV, while high voltage is typically above 36 kV.

Medium voltage systems are crucial for the reliable and efficient delivery of electricity. They allow for the transport of power over moderate distances with acceptable energy losses. The equipment used in medium voltage systems, such as transformers, switchgear, and cables, is designed to handle these voltages safely and effectively. Proper insulation and safety clearances are essential in medium voltage installations to prevent electrical hazards. The term "keskijännitteisen" is therefore a fundamental concept in Finnish electrical engineering and power distribution.
