What voltage level is categorized as medium voltage (MV)?

Medium voltage (MV) is typically defined within the range of electrical systems that operate from just above low voltage levels to near high voltage levels. Specifically, the categorization places the medium voltage range as exceeding 1 kV and going up to 34.5 kV. This range is important because it signifies the voltages used for distribution systems within substations and for medium-length transmission lines.

This designation plays a crucial role in various applications, including industrial and commercial electrical distribution systems, where equipment and infrastructure are designed to safely and efficiently handle voltages in this range. Understanding this classification is essential for professionals working in power systems, as it impacts safety standards, operational procedures, and equipment ratings.

The other options do not properly define medium voltage in accordance with industry standards, indicating either low voltage or high voltage levels that are outside the commonly accepted range for MV.
