Abstract: A support apparatus for an insulator arm is disclosed. The support apparatus for an insulator arm in accordance with an embodiment of the present invention includes: a first key cap connector and a second key cap connector coupled, respectively, with a first insulator arm and a second insulator arm that are divided, respectively, from a pair of insulator arms; a Y-shaped saddle coupled with the first key cap connector and the second key cap connector; and an insulator arm support metal fitting coupled with the Y-shaped saddle and connecting the pair of insulator arms with each other.

Abstract: Disclosed is a power transmission tower, which includes a tower body; first through sixth main insulation arms connected by one end thereof to the tower body with an angle with the tower body, respectively, and arranged radially and symmetrically about the tower body in a longitudinal direction; and first through eighth auxiliary insulation arms for selectively connecting the other end of the first through sixth main insulation arms and the tower body so that each of the auxiliary insulation arms constitutes each side of an octagon. Since the insulation arms are octagonally arranged, it is possible to reinforce a mechanical strength and enhance electric properties of the tower.

Abstract: Disclosed herein is an ELF or LF magnetic field measuring system, which can easily measure each magnetic field component existing in a free space generated by electric appliances or in a human body phantom filled with a specific fluid. A 3-axes magnetic field probe for use in the magnetic field measuring system comprises resistive lines in a protective sleeve rod electrically connected to the transmission board, an isotropic sensing head having a cubic shape, one end of the protective sleeve rod being rigidly connected to a corner point of the cubic sensing head where three faces coincide, and three bobbins adhered to three adjacent faces which coincide at a corner point diagonally opposite to the first corner point. A coil is wound on the periphery of each of the bobbins. The sensor is moved by an automatic mechanical machine to scan a pre-programmed surface where the magnetic field distribution is to the evaluated.
