Product description
Technical characteristics:
1. In
any grounding occasions, it can carry out the test normally by using
double-measuring method: non-contacting and accessing piles. No matter the
amount of grounding point is multiple or single.
2. Online measuring is
available. It can test the electric equipment under its working condition
without cutting from the grounding part.
3. The capacity of
anti-interference is strong. Even in the 500kV transformer substation, it can
produce the high-frequency current to filtrate the harmonic interference, like
50Hz or 100Hz from the electric current, then feedback the accurate
results.
4. The soil resistivity can be displayed automatically without
trivial calculation.
5. The inner storage with large capacity can save 100
groups of measuring datas.
6. The collocating charger and secondary battery
is designed for electricity saving, it will be cut automatically when exceeding
schedule time.
7. Four-line measurement ensures the accuracy of testing for
the grounding resistance below 0.7Ω.
8. The alarming system warms if
surpassing the limitation or using the incorrect testing condition.
9.
Self-testing is also available.
Application Range:
1. Non-accessory electrode measuring for grounding
resistance of communication and power system is available to do the test on the
concrete-covering ground.
2. The soil resistivity measuring under the
earthing grid construction is easy to calculate the depth of the grid for
builder.
3. The digital tester for traditional grounding resistance has a
full-scale application, which is replacing the pumping traditional meter.
4.
The resistance tester is connected in the looping circuit.
