Variable frequency anti-interference grounding impedance measuring instrument for grounding networkAdopting the current digital filtering frequency selection measurement technology, it has strong anti-interference ability and eliminates the errors caused by interference from power frequency induction, zero sequence current, harmonics, and stray signals in the measurement; Output a pure sine wave high-power signal as the test power supply, with an output power of 2KW, and collect data at multiple frequency points, especially suitable for measuring the grounding impedance of the ground grid. The system measures data accurately and stably, has strong anti-interference ability, good data repeatability, and is at a high level in China.

1. Adopting electronic countermeasure digital filtering technology, with anti-interference ability *, up to 100000 times. (Key performance, whether the measurement data is accurate and reliable, * depends on the performance indicator)

2. Multi point frequency conversion accurate frequency selection testing, rather than simple two-point frequency conversion.

3. Seven inch color screen, touch operation, easy and comfortable measurement with just a few clicks.

4. It has multiple functions and can measure parameters such as grounding impedance, grounding resistance, grounding reactance, soil resistivity, etc.

5. System output power of 2KW, current of 10A

6. The system automatically converts the range.

7. Each range can be calibrated separately to ensure high accuracy.

8. A high stability variable frequency source with pure sine wave output ensures the equivalence of test results and has multiple protection functions.

9. Display test data on a large screen and operate it in a foolproof manner.
