PROBLEM TO BE SOLVED: To provide a technology for securing insulation distance between an electronic component arranged on a substrate for current measurement and a branch bar serving as a conductive part in a distribution panel for measurement in which a plurality of CTs are arranged on the substrate for current measurement to measure a value of current flowing through each branch switch.SOLUTION: In a bus bar 2, a plurality of branch bars 6 are formed to which primary side terminals of a branch switch 3 are connected, and the current flowing through each branch bar 6 is measured by a current measurement unit 10 having a substrate 11 for current measurement on which current sensors 12 composed of CTs are arranged and installed. Inside of a through-hole 15 for branch bar insertion formed in the substrate 11 for current measurement, an insulation partition wall 16 is formed which penetrates through the substrate 11 for current measurement to secure the insulation distance between the substrate 11 for current measurement and the branch bar 6.SELECTED DRAWING: Figure 6 |
