Use environment
1, altitude is not more than 1000 meters
2, the ambient temperature is not higher than +40 perturbation, not less than -5
3, the relative humidity of the surrounding air is not greater than 85% (20 degrees)
4, no serious impact on the installation of transformer insulation insulation, steam, chemical deposition, pollution and other explosive and corrosive media
Note: 1, lmk-0.66 current transformer primary hole for the three row structure
2, small capacity corresponds to small current ratio, large capacity corresponds to high current ratio; such as 5-10 corresponding to 10VA corresponding to 100-600/5600/5, 100/5 corresponds to 10VA
