Product Description

Product overview

KDJK-10A can only locate the fault after the line has failed and stopped. The transmitter applies high voltage to the fault line to repeat the fault. The ultra-low frequency current flows from the transmitter to the fault point, enters the ground through the transit resistance and returns to the transmitter; Along the line, connect the sensor to the line through the insulating rod to detect the current. The sensor adopts a high sensitivity sensor, and its magnetic circuit does not need to be closed, which is convenient for hanging and taking operation to a large extent. The sensor detects the current on the line, automatically adjusts

the zero point, converts the analog signal into a digital signal, and then transmits it to the outside through wireless mode. The receiver on the ground receives the wireless signal sent by the sensor and displays the measurement results on the LCD screen.
 

Before the fault point, the current continues to exist, and after the fault point, the current disappears. The fault location can be quickly determined by rough segmentation (the long line is segmented by half method, and the branch line has priority to test the branch point), and then the accurate fixed point. KDJK-10A is applicable to single-phase metallic grounding, arc grounding, transit resistance grounding and other fault types; The ultra-low frequency signal can avoid the influence of system capacitance and adapt to low resistance to high resistance faults; Whether the line has branches, whether it is overhead line branch or cable branch, and whether the line is connected with a transformer has no impact on the equipment.
 

The KDJK-10A needs to be connected to the transmitter first in the use process, and the climbing pole is required to hook the
sensor in the positioning process. Therefore, the use is slightly complicated, but there are few restrictions on the positioning
test, and the positioning accuracy and fault confirmation are very high. KDJK-10A is the best test equipment to solve difficult
faults that can not be found by visual inspection after the line grounding fault occurs.
