| Zusammenfassung: | The utility model relates to a leakage protector tester, belonging to the technical field of a leakage protector testing device. According to the technical scheme, the leakage protector tester comprises a first test rod (2), a first test rod jack (6), a first current-limiting resistor (4), a second test rod jack (7) and a second test rod (8), all of which are connected in series and in sequence, wherein the leakage protector tester further comprises a digital meter head (3) which is connected in parallel with the first current-limiting resistor (4); and the leakage protector tester is characterized by further comprising a current regulator (5) located between the first current-limiting resistor (4) and the first test rod jack (6) and connected in series with both the first current-limiting resistor (4) and the first test rod jack (6). The leakage protector tester, disclosed by the utility model, has the beneficial effects that: a circuit equivalent impedance decreases slowly; a current ranging from 0 to 500 m |
