GY-318 Double clamp grounding resistance tester
The double jaw grounding resistance tester is suitable for testing the grounding resistance of various equipment and building grounding devices. Such as communication equipment, telecommunications Cable , machine room, power distribution line, electricity Pagoda Transmission lines, gas stations, factory grounding grids, lightning rods, etc., can also measure soil resistivity under various conditions. In addition to the function of traditional auxiliary grounding comparison and measurement of grounding resistance, the instrument also has the unique function of non auxiliary grounding comparison and measurement, which changes the traditional measurement principle and means of measuring grounding resistance. Using the two point comparison measurement principle and the double jaw measurement technology, it is unnecessary to make auxiliary grounding comparison and isolate the grounding body from the equipment, thus realizing online measurement. This machine has intelligent measurement function, which not only can automatically calibrate and realize jaw exchange, but also can store and browse the measurement results, and display Chinese prompt.
Product characteristics
1. It is suitable for any grounding place, and can be tested normally without multi-point or single point grounding
2. It can be measured online, and it is unnecessary to disconnect the grounding body from the equipment when the electrical equipment is in normal use. It can also be measured.
3. It has strong anti-interference ability and generates high-frequency current by itself, so as to filter 50Hz, 100Hz and other harmonic interference currents in the municipal power supply. It can measure accurately even in the environment of 500KV substation.
4. Automatic display of soil resistivity without complicated calculation.
5. Built in large capacity memory, which can store 100 groups of measurement data.
6. Configure charger and charge Battery , power saving design, automatic power-off after the specified time. 7. The four wire method can be used to measure the grounding resistance below 0.7 Ω accurately.
8. If the limit value is exceeded or the test condition is incorrect, the emergency signal prompt will be activated.
9. Automatic alignment function.
