description The utility model discloses a voltage and partial discharge signal sampling unit for an electrical test. The voltage and partial discharge signal sampling unit for the electrical test comprises capacitive voltage dividers C1 and C2, a coupling capacitor Ck, a detection impedance Zd, a line trap Zm, etc. The voltage and partial discharge signal sampling unit for the electrical test is characterized in that the capacitive voltage dividers, the coupling capacitor, and the detection impedance are installed in an insulated cylinder side by side, the test voltage and partial discharge signal sampling is completed at the same time, the line trap is connected between the capacitive voltage dividers and the coupling capacitor Ck and the detection impedance to weaken the influence of the partial discharge of a system voltage boosting portion on the partial discharge measurement of a tested element and prevent the partial discharge signals of the tested element from being transmitted to the system voltage boosting porti
