Cable Fault Pre-Locator

Kusam-Meco is a pioneer in the field of Electronic Testing & Measuring Instruments in India since 1983. We have a very wide range of instruments which cover the requirements of almost every Industry.

We have pleasure in introducing to you our new product “CABLE FAULT PRE-LOCATOR” which is extensively used for cable fault finding in Railways. We shall be glad to receive your enquires for the same which will be attended promptly.

“KUSAM-MECO” underground Cable Fault Pre-locator Model KM-CFL-620 is an automatic Cable Fault Locator which adopts ARM, FPGA & Dot Matrix Color LCD display Technology. This tester combines both pulse reflecting technology (TDR) & intelligent Bridge testing (Bridge) for measuring the exact fault location such as broken line, cross faults, earthing, poor insulation & poor contact of the lead covered cables as well as plastic cables. It is capable of giving IR tests in Bridge mode.

It is a microprocessor based fault locator with a user friendly menu. It is easy to operate. It tests almost all power cables, telecom & signal cables. It has an English menu which is easy to understand & use. With Megameter & Ohmmeter it enables to test insulation resistance & loop resistance. It has USB Port for uploading test data to computer.

Small size, light weight and ABS plastic housing which is ergonomically designed for easy use by user. Menu driven simple operation. Measurement maximum 8 km in selectable ranges. Tests any type of copper telecom and signal cables. Range, VOP and Gain are selected automatically. It has Color LCD Display (480 x 280 dots) & Automatic testing mode. Both pulse reflection (TDR) and intelligent bridge (Bridge) testing for open, short, or low insulation cable faults. With mega meter it enables to test insulation resistance and loop resistance. Six function keys and simple operation. Manual testing function is also available. With 4 GB USB Pen drive, it is easy to upload memory data to computer. Rechargeable lithium battery with intelligent charger & charging time is 3hours & Charging voltage 230V +/-10%, 50Hz, single phase. Continued 8 hours operating time on internal battery. Rugged construction and easy to carry on site.

In TDR MODE Fault Distance Range is 8 km (240m, 480m, 1000m, 2000m,4000m,8000m) & Accuracy is 1 meter. Cable Constant (VOP) range is 100 – 300. Sampling Speed 100 MHZ. Testing accuracy is+/- 1% × cable length. Pulse Width 40ns - 10us. Pulse Waveform Two polarity pulse. Pulse Amplitude 0 - 30V adjustment adaptive. Impedance matching Automatic. Output Impedance 25 - 120 adaptive. Gain adjustment is Automatic and Manual & Range Control is 0 – 9, Resolution 1 Meter, Memory Location U – disk, Serial port for PC / Printer is USB.

In BRIDGE MODE the max length of testing cable is 10 Km & Max. poor insulation resistance is 100 M Ohm. Testing accuracy +/- 1% x cable length & maximum resistance of defective insulation is 100 M Ohm.

IN TDR Mode a narrow electromagnetic frequency pulse of 40ns - 10us with a fast rise time is sent on the cable that reflects back from the fault point /far end where the impedance was mismatched or changed. The velocity of propagation (VOP) for each cable depending on the cable dimension and material is set and the distance to the fault is then computed automatically and displayed in meter on LCD screen.

In Bridge Mode the equipment has menu driven insulation tester capable of giving IR test and displays insulation resistance in Meg Ohm. A healthy core/pair is used to get the loop resistance of the cable under test. When the faulty core/pair is connected to the equipment, balancing of the bridge is done automatically by the intelligent circuit incorporated in the equipment. However, the balancing can also be done manually in specific cases. After the balancing, the result of the fault distance from sending end is displayed on the screen.

It is supplied with Carrying case, Re-chargeable battery charger / adapter, Connecting test cables, Software CD 4GB Pen Drive and User Manual.
