  • Page 7: Principle Of Work

    The classic pulse TDR is used to defi ne a distance to the place of wave resistance changing for all cable types. The devise can be used to: Measurement of distance to place of cable fault; Defi nition of fault type; Measurement of distance between heterogeneity of wave resistance;...
  • Page 8 the estimation of contact infl uence of the line in which the measuring pulse o n other line in which the induced signal is observed is got is possible. Also this mode is useful for searching of wire reversing location (split). The pulse is propagate in the line and reaches a wire reversing location, which is characterized by a sharp increasing of electromagnetic communication between the pairs.
  • Page 9 There are two cursors on the TDR screen, between them the distance is measured on the trace. To make a cursor an active – press the ◄► keys. To vertical move a trace – press the ▲▼ key. To operate with the trace gauges use the following keys: [PULSE], [RANGE], [AMPLIFICATION].
  • Page 10 DSP TDR is used for determination of the distance to the place of wave resistance changing for all cable type. In the IRK-PRO GAMMA device, along with the classical approach there is the new approach, based on the using of wavelet functions as a measuring pulse.
  • Page 11 TRACE VIEWING Linear scale There are two cursors on the TDR screen, between them the distance is measured on the trace. To make a cursor an active – press the ◄► keys. To vertical move a trace – press the ▲▼ key.
  • Page 12 Logarithmic scale «Logarithm» The screen in logarithmic scale: This scale is used for the fast-access retrieval of the heterogeneity. The total viewing range is 100 dB. The top screen part is 0 dB, the bottom screen part –100 dB. The [AMPLIFICATION] key do not have an infl...
  • Page 13 MEASUREMENT OF THE DISTANCE Measurement of the distance must be made after setting of VF or selecting of a cable from the List. Measurement of distance is always carried out between two cursors. For measurement of the distance from the cable beginning to heterogeneity it is necessary to make a zero cursor become an active.
  • Page 14 The expected limit of leakage defi nition is increasing for the cable: of Category 3 from the value 110 Ohm up to 11 kOhm, of Category 4 from 40kOhm up to 50 kOhm. Example We are use the IRK-PRO GAMMA device in the mode of DSP TDR with the following hookup:...
  • Page 15 Leakage During the amplifi cation of 36 dB on the cable of 600m with the leakage on the distance of 300 m were obtained the following trace: Obviously, the leakage of 13 kOhm is simply defi ned rather than open-cable. The open-cable does not cause an asymmetry and its signal is successfully attenuated at the expense of cable pair symmetry.
  • Page 16 BRIDGE MEASUREMENTS You can select bridge measurements in Main Menu. MULTIFUNCTIONAL SCREEN The multifunctional screen is divided on 4 sections: 1. the protocol section allows to protocol the measurements results. 2. to select the switching section mode (on the left part of the screen) - press the F1 – F6 keys.

    LOOP MODE Measuring hookup: Measuring section: The loop is measured between only А & В wires. The measurement result is counted in the cable length if you have selected a cable type.

  • Page 21 SEARCHING OF THE CABLE INSULATION FAULT The technique of search The measuring hookup is shown on the fi gure. Measuring lead from a socket B connect to a faulted wire, a lead A connect to a good wire, a lead C connect to a cable shield. The wire with bad insulation on the far-end is connected with good wire.
  • Page 22 A cable length is entered incorrectly At defi nition of an insulation fault locate the device fi rst of all measure a loop. Then it remembers the cable length L in Ohms. Next step is to measure distance to an insulation fault locate. The measuring hookups of IRK-PRO measures distance to fault locate X in Ohms.
  • Page 23 To check up the result, it is better to make measurements from two ends (including K) and to ensure the indications sum is equal to the cable length. The factor K shows the attitude of an additional error ΔК, receiving during the calculations to a measurement passport error Δ: ΔК...
  • Page 24 FAULT SEARCHING SCENARIO After cable selecting you can start a fault searching process. This process consists of several measurements, described in protocol. To fi nd a fault you should fi ll a protocol. 1. Back wire searching. Connect a С wire to cable shield. During open-circuit fi nd a wire with low insulation by the B wire.
  • Page 25 2. The resistance parity АС/ВС must be not worse than 400. To check parity – measure a K factor (must be not more than 0,005). 3 Turn on the LOOP mode; connect a loop at the far end between good and bad wires. Control the connection quality at the far end according the device indication.
  • Page 26 4. Turn on the LEAKAGE mode and start a fault searching by the [OK] key. The device will display the distance to the insulation fault location. 5. The result is calculated according to K factor will be shown in a corresponding row. If there is impossible to select a good wire –...
  • Page 27 What will be if to turn on the leakage not to measure a loop by the fi lter? If it is the loop fi rst measurement the device will not make the fault searching because it has nothing to compare result. If you have already measured a loop by the fi lter the device has remembered this value and has accepted it as a cable length.
  • Page 28 SEARCHING OF THE OPEN CABLE If there are undamaged cable cores in the cable, then the device can defi ne distance up to open-cable by comparison of good cable core (pair) capacity and open-cable core (pair) capacity. Such method does not use a cable gauges. It is possible to start the measurements without choosing a cable Only for a cable without sections! The searching consists of 3 stages described in protocol.
  • Page 30 Scheduled measurements The device allows automating the measurement process, result record and result reading of scheduled measurements – the cable isolation resistance and electric capacity or a loop and asymmetry. To make measurements automatically and input the results in memory, the cable should be entered in “List”.
  • Page 31 Attention!!! The data are deleted not only from devices screen but also from memory. To avoid the loss – don’t forget to transfer the measurement results on to PC memory. If there is no scheduled measurement of selected cable – you will see an empty table. SETUP OF THE MEASUREMENT GAUGES There are 4 types of commutations, defi...
