產(chǎn)品簡介

優(yōu)良的接地系統(tǒng)是電力、電信、電氣設備安全可靠運行的重要保證。接地電阻大小是接地系統(tǒng)品質(zhì)優(yōu)劣的評判依據(jù)。、快速、簡捷、可靠的接地電阻測量方法，已成為防雷接地領域內(nèi)技術進步的迫切需要。NASJX雙鉗接地電阻測試儀適用于電信、電力、氣象、機房、電力配電線路、鐵塔輸電線路、加油站、工廠接地網(wǎng)、避雷針等。

NASJX雙鉗接地電阻測試儀除了具有傳統(tǒng)打輔助地極測接地電阻的功能外，還具備了無輔助地極測量的功能，改變了測試接地電阻傳統(tǒng)的測量原理和手段：采用雙鉗口非接觸測量技術無需打輔助地極，也無需將接地體與負載隔離，實現(xiàn)了在線測量。在單點接地系統(tǒng)、干擾性強等條件下，可以采用打輔助地極的測量方式進行測量。

Product introduction 

Excellent grounding system is very improtant to ensure the power, telecommunications, electrical equipment safe and reliable operation. Grounding resistance grounding system size is d on the quality of the merits of the judgment. Accurate, fast, simple and reliable grounding resistance measurement method, the area has become a lightning protection and grounding technological advances are urgently needed. NASJX double clamp earth resistance tester for telecommunications, electricity, weather, room, power distribution lines, tower transmission lines, gas stations, factories grounding, lightning and so on.

NASJX has traditional fight auxiliary earth ground resistance measurement functions, also has no auxiliary measuring the unique features of the earth, changing the traditional testing ground resistance measurement principle and means: Double clamp mouth non-contact measurement technology eliminates the need to fight auxiliary earth, and without the grounding body and load isolation, to achieve an online survey. In the single-point grounding system, strong interference and other conditions, can be used to fight the auxiliary earth electrode measurement measurement.

Product information

1, jaw and host as a whole set. To avoid measurement errors, do not use the jaw of NASJX Double Clamp Ground Resistance Tester hosts for other host.

2, must keep iron core contact surfaces of the jaw clean, or else contaminated instrument jaw will reduce measurement accuracy.

3, keep the jaws closed well during the test to avoid stuck phenomenon.
