PROBLEM TO BE SOLVED: To provide an insulation plug for instrument direct coupling T-shape enabling voltage detecting work on a low voltage detector and low voltage equipment and an instrument direct coupling T-shape terminal connection part using the same.SOLUTION: An insulation plug 1D includes: a roughly truncated cone insulator 1a such as an epoxide resin; a high-voltage electrode 1b, embedded in one end part of the insulator 1a, coupled to an instrument side conductor 3; a voltage detecting electrode 1c embedded in the other end part of the insulator 1a so as to be arranged oppositely to the high-voltage electrode 1b; and a ground layer 1d provided so as to be in contact with the voltage detecting electrode 1c in a concentric manner with the voltage detecting electrode 1c. |
