<p><P>PROBLEM TO BE SOLVED: To measure power factor and errors, without fail and properly, with respect to a new type of terminal board whose array pitches of a transformer side terminal and an instrument-side terminal are different from those of old terminal board. <P>SOLUTION: In a terminal jack 61 is mounted freely attachably and removably on the terminal board disposed, between a transformer for an instrument connected to a high-voltage receiving cable of AC three-phase 3-wire type and an instrument for electrical energy, and to this jack, connection terminals extending from a measuring instrument are connected in a freely attachable and removable manner, each of the transformer-side terminal 63 and the instrument-side terminal 64 is provided at two opposing sides of a rectangular frame-like base 62; a plurality of blade type contactors 65, 66 which are inserted into corresponding blade receiving contactors of the terminal board, are provided along each side on the back sides of the transformer-side terminal 63 and the instrument-side terminal 64; a plurality of blade receiving contactors 67, 68, in which the blade type contactors extending from the measuring instrument are inserted, are arranged along each side on the front side of the transformer-side terminal 63 and the instrument-side terminal 64 at array pitches different from the blade-type contactors 65, 66 on the back side; and two switches 69, 70, which connect and disconnect the transformer side terminal 63 and the instrument side terminal 64, are provided on the front side of the remaining two opposing sides of the rectangular frame-like base 62. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
