○ Measurement categories (Over-voltage categories)

To ensure safe operation of measuring instruments, IEC61010 establishes safety

standards for various electrical environments, categorized as CATⅠ to CATⅣ, and called

measurement categories. Higher-numbered categories correspond to electrical

environments with greater momentary energy, so a measuring instrument designed for

CATⅢenvironments can endure greater momentary energy than one designed for CATⅡ.

CAT.Ⅰ: Secondary electrical circuits connected to an AC electrical outlet through a

transformer or similar device.

CAT.Ⅱ: Primary electrical circuits of equipment connected to an AC electrical outlet by a

power cord.

CAT.Ⅲ: Primary electrical circuits of the equipment connected directly to the distribution

panel, and feeders from the distribution panel to outlets.

CAT.Ⅳ: The circuit from the service drop to the service entrance, and to the power meter

and primary over-current protection device (distribution panel).
