The term "kV" stands for kilovolt, which is a unit of electrical potential equal to 1,000 volts. It is commonly used in electrical engineering and power distribution to measure high voltages. Understanding kV is essential for working with electrical systems, as it helps determine the capacity and safety of electrical equipment. In power transmission, high voltages like kV are used to efficiently transport electricity over long distances. This reduces energy loss due to resistance in the wires. Devices such as transformers and circuit breakers are designed to handle specific kV levels, ensuring safe and effective operation in systems like power grids and industrial facilities.
