Abstract
A module type sensor includes a casing including a casing upper surface, a first casing side surface which is bent downward from the casing upper surface and has a lower end upwardly separated from a path through which a transmission line passes, and a second casing side surface which is bent downward from the casing upper surface and has a fixing bracket extending by being outwardly bent; a body unit fixedly installed inside the casing, formed of an insulator, supported by the printed circuit board at a lower end, and having, at a center, an opening which is open toward the transmission line; and a sensing substrate unit fixedly installed on an upper portion of the body unit, and including a voltage sensing circuit which is capacitively coupled to the transmission line exposed through the opening and a current sensing circuit which is inductively coupled to the transmission line.
