The invention relates to a grounding condition tester for high-voltage test. The grounding condition tester is characterized by comprising a housing and a grounding test circuit arranged in the housing, wherein a current display screen, an adjustment knob, a test result display screen and a tester switch which are connected with the grounding test circuit are arranged on an operating panel of the housing; and the grounding test circuit comprises a direct current power supply U, a tester switch K, a loop current test and display unit A, a variable resistor Rt for adjusting an initial current value of a loop, two test terminals J1 and J2, a comparison unit B, a tester constant setting unit C and a test result display screen D. The grounding condition tester is rational in design and can automatically test and display a grounding condition of test equipment; when the grounding condition is poor, a buzzer sounds an alarm to remind a tester of the grounding condition, so that the probability of an accident caused by the poor grounding condition is prevented, and the uncertainties caused by manmade factors are avoided; and therefore, the safety of people and equipment during the high-voltage test is effectively guaranteed.
