Anti Jamming Earth Resistance Meter 3A Electrical Ground Testing Equipment

 

 

1. Product Name:

Grounding resistance tester 3A

 

 

2. Notes

 

a. Current electrode should be in a wet situation to ensure that ground resistance is relatively small (less that 20Ω is proper. Spreading some water is allowed to lower the ground resistance ), and the instrument can output ideal test current.

 

b. During the testing process, please don’t touch the instrument to guarantee safety because the maximum output voltage between C1 and C2 can be 100V. 

 

c. Please do be careful when measuring the 500kV substation and other large nets because there will be high induced voltage on the long current line and voltage lines.

 

d. Considering human safety and the accuracy of measurement, please make sure that the ground terminal of the instrument can connect with ground.

 

3. Equipment Description:

1. Measurement scope: 0~150Ω (including impedance of current pile)
2. Maximum output voltage: AC 400V (45Hz, 55Hz, double frequency, sine wave)
3. Maximum output current: AC 3A (45Hz, 55Hz, double frequency, sine wave)
4. Measurement error: ± (reading×2%+0.005Ω)
5. Anti-jamming capacity: power frequency resistance 50Hz voltage 10V
6. Current output gears: 3/2.5/2/1.5/1A, one gear every 0.5A, totalling 9 gears.
7.  Requirement for measuring line:
    Sectional area of cooper core of current line≥1.5mm2
    Sectional area of cooper core of voltage line≥1.0mm2
8. Electric power supply: AC 220V±10%, 50Hz
9. Contour dimension: 440×350×210mm3
10. Instrument weight: 30kg
