  1. Introduction:
    Insulated Metal Sheathed Cable Tester Nylon Sheath Cable Fault Test Equipment
    Insulated Metal Sheathed Cable Tester Nylon Sheath Cable Fault Test Equipment
    Along with the low-voltage pulse reflectometry, our systems implement advanced high-voltage pre-location technologies that allow to determine the distance to faults of various types with a minimal harmful effect on the cable lines.High level of safety during the testing with our cable test vans and mobile systems is ensured by built-in protection against overcurrent, overvoltage and overheating, as well as by the use of a continuous grounding monitoring, vehicle door closure sensors and self-health check monitoring.
    High speed sample system and high bandwidth input circuit are integrated in the tester to get the exact reflection curve of signal so that the distance of fault point to signal sample point can be calculated in high accuracy and high resolution Special sound location tester configuration can be applied to locate the fault point more exactly.
    The cable fault tester is suitable for measuring power cables, high-frequency coaxial cables, local telephone cables, street lamp cables, low-resistance of short-circuit, open-circuit disconnection faults, and various materials of various materials with different cross-sections and different media. Leakage and high resistance flashover faults. A powerful cable management system that automatically generates test reports.
    It can test a variety of 35KV under different voltage grade, different sections, different media and all kinds of material of power cable faults, including: open circuit, short circuit, low resistance, high resistance, high resistance leak flashover fault.
    It can be any cable length measurement of radio wave propagation in the known speed.It can test the power cables buried path and buried depth.route tracing evaluation of electric lines and cables.




    Overview:
    Good solution of the pinpointing of single phase to earth fault as signal transmitter and it can also matched with FLD-903P EHV cable sheath fault pinpointer to do sheath fault pinpointing.

    1.1 Feather
  2. Auto testing. Big LCD displays the distance directly. Easy operation and solute the difficulty of HV Bridge balance adjusting.
  3. Overcome the HV bridge disadvantage that can't locating because lack of good insulation sheath in site.
  4. Built-in HV continuous current. Output voltage and current is continuously adjustable and period optional.
  5. Inject signal to reappear the fault, easy pinpointing with stable current signal.
  6. VLF signal to avoid effect of system distributed capacitance and easy to pinpoint the high resistance fault.
  7. Support both power supply and storage battery supply
  8. Light weight and easy to portable.

    Power socket: contact with 220V power
    Protective tube: change protective tube if needed
    Power switch: turn on/off the device
    HV on: when turn on the device, press this button when output adjustment on the ZERO position to output HV signal.
    HV off: Stop HV output
    Zero: indicate that the output voltage on the zero position
    Protect: when the device become protect mode, this indicator will be bright to show the device is in protect blocking state. Adjust the Output adjust button to Zero position to reset the indicator.
    Output adjust: adjust the output current and voltage. When it on the Zero position, to press HV on button to start the transmitter signal output function.
    Protect current: indicate the input current value. If current is over default max. 4A,the device will be stopped. Then it is needed to zero the output adjustment button to set protective circuit to readjustment the current.
    Output voltage: indicate the value of output voltage
    Earth: earth terminal to contact with the earth line to connect the earth mat.
    HV out: connect the fault line. According the local state to clip the switchgear wire or connect the faulty line with rod of patch board 
    Test ground: connect with earth mat.
    3. Method of application

    3.1 Work principle

    Transmitter output is impulse DC signal which frequency is 1Hz.Low frequency less impact by the system division capacitance. It is proved the 1Hz signal can satisfy most requirements from the testing site.
    The limited voltage of the transmitter is 8kV.It is equal the phase voltage peak value of 10kV line. If the voltage too high, it will bring line major insulation broken. If it's too low, the fault can't be reappeared. This value could be adjusted when production.
    Hanging the sensor along with the line to test the current. Sensor test the current on the line and automatic zero setting then converse analog signal into the digital signals to transmit by wireless mode.

    3.2 Operation of the transmitter

    3.2.1 Wiring
    First beak the fault line, then connect the it with utility power(220V).Connect the earth line with Protect ground terminal and the earth grid.
    Wire the earth test line (HV line with black clip) to the earth test grounding and earth gird.

    We could wire the output line of the fault line according the site conditions. Connect the short line which has a red clip with the line terminal and the line side of the switchgear. If must connect it on the overhead line ,we suggest to use the long line. Connect its high voltage outlet with the line terminal, and then connect the other line on the insulation hanging rod, then hang the rod on the fault line.


    3.2.2 Power supply
    Open the power switch. Now the transmitter still doesn't transmit.

    3.2.3 Start and output
    First adjust the output adjust button to ZERO.Now the Zero is bright.
    Then press HV on button to begin the output. Now the HV indicator is light.
    Turn up the output adjust button slowly to rise the current but make sure the protective indicator doesn't light. If this indicator light, it indicates the faulty line has small resistance so the input current is too high. Now it's needed to adjust the output adjust button to ZERO anticlockwise and readjust to suitable position.

    3.2.4 Stop output.
    If need to stop the output, press HV off button

    3.2.5 After test, turn off power and disconnect the wiring.
