<p>PROBLEM TO BE SOLVED: To provide an excellent high-voltage test device contributing to a reduction of size of a building of a laboratory by shortening an insulation distance and increasing a measurement sensitivity by suppressing the occurrence of aerial partial electric discharge. SOLUTION: Output terminals 14a and 15a extracted to the outside are formed on an impulse generator 14 and a test transformer 15 having SF 6 gas sealed therein, and a duct line bus 10 is attached to the impulse generator 14. The SF 6 gas is sealed inside the duct line bus 10, and the output terminals 14a and 15a and an output selector switch 8 are stored in the duct line bus 10. The output selector switch 8 is formed so as to connect either of the output terminals 14a and 15a selectively to transformation equipment.</p> |
