南澳电气 NASJX双钳接地电阻测试仪 **、快速、简捷、可靠的接地电阻测量方法

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。**、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、加油站、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。

Product introduction 

Excellent grounding system is very improtant to ensure the power, telecommunications, electrical equipment safe and reliableoperation.Groundingresistance grounding system size is based on the quality of the merits of the judgment. Accurate, fast, simple and reliable grounding resistance measurement method, the area hasbecome alightningprotection and grounding technological advances are urgently needed. NASJX double clamp earth resistance tester for telecommunications, electricity, weather, room, powerdistributionlines, towertransmission lines, gas stations, factories grounding, lightning and so on.

NASJX has traditional fight auxiliary earth ground resistance measurement functions, also has no auxiliary measuring theuniquefeatures of theearth, changing the traditional testing ground resistance measurement principle and means: Double clamp mouth non-contact measurement technology eliminates the need to fightauxiliaryearth, andwithout 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 fighttheauxiliary earthelectrode 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 ResistanceTesterhosts for otherhost.

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.
