             There are many types of small current grounding line selection devices on the market. The purpose is to find the fault line of single-phase grounding fault in small current grounding system, and its functions are roughly the same.

              At present, the small current grounding line selection device is divided into two types, one is the ordinary single-chip microcomputer small current grounding line selection device, and the other is the industrial computer small current grounding line selection device. At present, there are not many manufacturers of industrial computer small current grounding line selection devices in the market. Most manufacturers produce ordinary small current grounding line selection devices.

              When purchasing, how to distinguish between ordinary small current grounding line selection device and industrial computer small current grounding line selection device? For the equipment produced by our company, the first is the different models. The model of ordinary small current grounding line selection device is smr-zn09a (b), and the model of industrial computer small current grounding line selection device is smr-zn09icm. Secondly, there are differences in functions. The small current grounding line selection device of industrial control computer has more functions than the ordinary one. Functionally, the ordinary small current line selection device adopts the steady-state algorithm, and the small current line selection device of industrial control computer adopts the steady-state algorithm + transient algorithm. Not only that, the small current grounding line selection device of industrial control computer also increases the wave recording function, fault phase judgment, Pt line break alarm Reclosing function, wheel cutting function and other functions.

              The prices of these two devices are also different. The functions of low current grounding line selection device of industrial computer are increased, the price will be higher than that of ordinary type, and the accuracy of line selection will be more accurate. At present, China Southern Power Grid uses industrial computer small current grounding line selection device.
