Ground Earth Resistance Tester
2678X
Shenzhen Chuangxin Instruments Co., Ltd.
Ground Earth Resistance Tester verifies the integrity (continuity) of the protective bonding of the equipment (Class I equipment) designed to secure safety through the basic insulation and protective earthing. It is also called earth (ground) bonding test. If the continuity of the protective bonding is confirmed, we can conclude that the equipment has the requirements for preventing electric shock even if the insulation between the primary circuit and the accessible conductive section fails and a fault current flows through the distribution system.

Earth Ground Meters
The earth tester determines ground resistance for both specific and ohm resistances. The earth tester is powered by batteries and have a clock timer function (3 minutes), Data-Hold function, a 3 ½ positions LCD display and their dimensions are 163 x 100 x 50 mm. Resistance ranges come from 20, 200 to 2000 ohms. They have a resolution of 10 / 100 mΩ / 1 Ω. The earth tester measure resistance by means of a constant reverse current (approx. 800 Hz, 2 mA). To measure ground voltage a rectifier is used (5 kΩ/V aprox. 40...500 Hz). The earth tester PKT-2630 series have a small format as well as multiple functions.

Stimulus Induced Fault Testing
SIFT
SIFT allows for the analysis of numerous stimuli to identify speed, fault, and parametric differences in silicon. The heart of the SIFT technique revolves around intentionally disturbing devices with external stimuli and comparing the test criteria to reference parts or timing/voltage sensitivities. Synchronous interfacing is possible to any tester without any wiring or program changes. The system can be based on either a motorized probe station or portable microscope stand for test head applications.

Power Quality Measurement & Digital Fault Recording
In view of the growing number of factors with a disturbing influence on power systems and the ever increasing sensitivity of devices and installations on the consumer side, simple monitoring criteria such as undervoltage or overcurrent are no longer adequate. Reliable registration of all the relevant processes within the electrical power system calls for constant observation of a wide variety of derived parameters, such as individual harmonic content, system unbalance and interharmonics, and the swift identification of even slight deviations from the norm.
