Product Description

GDF-3000 DC System Earth Fault Tester

Product Description

In DC system, there are many earth faults including indirect earth fault, non-metal earth fault, loop earth fault, positive and negative earthing fault, positive and negative balance earth fault, multi-point earth fault. GDF-3000 Earth Fault Tester for DC System locates these earth faults and displays the parameters of system voltage, earth voltage, earth resistance and earth impedance of branches accurately. 

  • Adapted DC system of various voltage level, with intelligent direct judgment of earthing point, fast and accurate to locate multi-points earth fault, high resistance earth fault, positive and negative earth fault and loop earth fault.
  • Friendly interface, clear and easy operation. Display insulation index vividly and real-time display waveform. It reflects insulation level of every branches and earth fault direction.
  • High accuracy detection. With high precise sensor, resolution up to 0.01mA. Better linearity and broad detection range.
  • Strong interference ability. It can eliminate the AC/DC series of electric faults effectively, with no limits of earth fault distance.
  • Small output power. The transmitter generates current of 1.0-5.0mA intelligently according to on-site situation. The max.
  • Power is lower than 0.05W, to ensure safe and reliable operation of DC system.
  • Humanized appearance design of engineering mechanics, convenient to use and easy to carry.
  • With good components and scientific production management, ensuring high reliability.
  • Voltage: 220V±15%, 110V±10%, 48V±10%, 24V±10%, or customized voltage level.
  • Capacitance range: System to the earth, total capacitance ≤100uF
                                         Single branch to the earth, ≤5uF
  • Output power of Transmitter: ≤ 0.05W.
  • Measurement range of Transmitter: Bus bar to the earth: 0-1000kΩ
                                                                     System to the earth: 0-1000kΩ
  • Accuracy of Receiver: <10µA
  • Locating range of Receiver: 220V DC system: 0-500kΩ; 110V DC system: 0-250kΩ; 48V DC system: 0-125kΩ
