The radiation power of a high-current vacuum arc 8 mm long was measured in the vacuum ultraviolet region and the results were compared with measurements in a short arc (4 mm). With increasing arc length, the increase in radiation power in the vacuum ultraviolet region (100≤ λ ≤ 175 nm) is less pronounced than in the 175-400 nm range. This confirms the view that the main increase in radiation power in an arc with developed anodic activity occurs due to the emission of atomic lines. The proportion of total energy transferred by radiation increases with arc lengthening and reaches a maximum of 30 %. Keywords: vacuum arc. radiation power, low-temperature plasma, electromagnetic radiation, electric arc.
