YLDL-211Single phase grounding fault point locator for distribution linesUsed for locating single-phase grounding fault points in 6kV, 10kV, 20kV, and 35kV overhead lines. For hidden grounding faults such as porcelain bottle breakdown and lightning arrester breakdown, the search is fast, time-saving and labor-saving, and can shorten the search time by 60%.

▍ Product functions and features 　↴

•Search quickly and accuratelyAdopting a multi evidence fusion fault location discrimination technology based on time sequence and phase, it is not affected by measurement distance (line height) errors, line length, and number of branches, and the fault point error does not exceed 1 meter
•Wide applicabilityMulti mode measurement technology, suitable for locating various types of grounding faults (including low resistance grounding, high resistance grounding, arc grounding, and hybrid grounding)
•Easy to carry and useThe signal source is powered by lithium batteries, which are small in size, light in weight, and easy to carry. It comes with its own power supply, does not require a generator, and can be charged in vehicles
•Safe and reliable operationThe operator operates through an insulated rod, and the device is equipped with overvoltage protection inside to ensure safe operation
