SB-JY DC Ground Fault Finder avoids the shortcomings of traditional search methods, can not affect the work of the current system under ground fault finding; achieve a "convenient", "reliability", "security", "fast", "online", "direct" Find a DC system effectively detect ground fault function; The instrument has a high sensitivity, anti-interference ability, small size, light weight, easy to use features; Find a DC system grounding fault, you do not Disconnect the power, ground positioning can be achieved. Instrument can detect not only the DC system grounding resistor, the DC system can also detect earth capacitance values. SB-JY DC Ground Fault Finder is the company developed a new DC ground instrumentation, widely used in electric power, petrochemical, metallurgy, telecommunications, railway and other DC system grounding fault lookup; instrumentation basic principle: the signal generator test object on the pile 2.5Hz and ground to launch a low frequency between the voltage signal generated at the fault point of a leakage current, the fault current receiver, calculating the grounding resistance and capacitance values, and displayed on the LCD. The instrument can fully eliminate capacitive grounding illusion, is a versatile, high-performance, low-cost intelligent instrument. Features Functions Features 1, various parameters keyboard settings, flexible, can be changed at any time. 2, according to the actual situation of the scene insulation set the alarm value. 3, suitable for a variety of different types of DC system, no voltage level restrictions. 4, a variety of sampling receiver is optional, meet different types of circuit measurements, and can be replaced at any time. 5, ground loop resistance measurement values ??and the ground loop capacitance value, comprehensive, accurate removal of grounding six capacitance illusion, ultra-low frequency signal injection, the DC is not affected. 7, low-power, battery power supply can be used continuously for 5 hours. 8, no debugging, easy to use.
