NASJX双钳接地电阻测试仪

产品简介

优良的接地系统是电力、电信、电气设备安全可靠运行的重要保证。接地电阻大小是接地系统品质优劣的评判依据。精确、快速、简捷、可靠的接地电阻测量方法，已成为防雷接地领域内技术进步的迫切需要。NASJX双钳接地电阻测试仪适用于电信、电力、气象、机房、电力配电线路、铁塔输电线路、工厂接地网、避雷针等。

NASJX双钳接地电阻测试仪除了具有传统打辅助地极测接地电阻的功能外，还具备了无辅助地极测量的独特功能，改变了测试接地电阻传统的测量原理和手段：采用双钳口非接触测量技术无需打辅助地极，也无需将接地体与负载隔离，实现了在线测量。在单点接地系统、干扰性强等条件下，可以采用打辅助地极的测量方式进行测量。

NASJX Dual-Clamp Ground Resistance Tester

Product Overview

A high-quality grounding system is essential for the safe and reliable operation of power, telecommunications, and electrical equipment. Ground resistance value serves as a key indicator of grounding system performance. Accurate, fast, and reliable ground resistance measurement methods are critical for advancements in lightning protection and grounding technology.

The NASJX Dual-Clamp Ground Resistance Tester is designed for diverse applications including telecommunications, power systems, meteorological stations, data centers, power distribution lines, transmission towers, factory grounding networks, and lightning rods.

Unlike traditional methods requiring auxiliary electrodes, the NASJX introduces non-contact dual-clamp measurement technology, enabling live testing without disconnecting grounding conductors or installing auxiliary electrodes. For single-point grounding systems or high-interference environments, traditional auxiliary electrode measurement remains available.
