UNDERGROUND CABLE FAULT PRE LOCATING EQUIPMENT
"KUSAM-MECO" underground Cable Fault Pre-locator 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. (Model-KM-CFPL-620B)) (Model-KM-CFPL-620B)). 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.

OPERATING PRINCIPLE :
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.
BRIDGE Mode(Model-KM-CFPL-620B)
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.
ACCESSORIES :
Carrying case, Re-chargeable battery charger / adapter , Connecting test cables, Software CD 4GB Pen Drive and User Manual.
