Technical Data Receiving frequency : 50 Hz -10 kHz, 815 Hz , 2 kHZ, 10 kHZ + 2 adjustable frequencies 50 Hz - 10 kHZ Filter- Digital Passive reception - 50/60 Hz mains signal Amplification ; 0- 38 dB Propagation velocity range : 0-96ms Operating Temp - -20 Degree centigate .... + 55 degree centigrate Protection - IP54 Power supply - 4x1.5 V cel (IEC LR6) Battery life ( Normal operation) - over 50h Cables All cables reqd for operation of cable testing system shall be mounted on drums with take out facility. The cable drum should be proided with screw terminal for protective earth cconnection with a monitoring switch so that putting in tgo operatioin of the sdystem is only possible when the protective earth lead is conected on the system side. The particulars of cables required are indicated belows: Earthing Cable : 25 M earthing cable 16 sq mm multistranded flexible copper with rubberised insulation to connect. Power supply cable : 25 m three core cable for connection of equipment to mains ( max 16 A) HV cable: 25 m , co-axial HV cable to serve as connection between cable fault locator and the cable to be tested. The ross section of core andshied should be 6 sq mm . The lead should be suitable for an operating voltage up to 70 KV DC . EPR insulation should be used , so that cable can remain flexible even in extreme cold condition. Contd.../-

Mounting The eqpt should be mounted on zink coated suitable base frame wheels so that eqpt can be easily transported in a vehicle, and once inserted in a vehicle it can be locked safe for transport. Complete eqpt should be provided as a single system. Safety measures The instrument should have a built -in automatic discharge feature as per which a cable (installatiion) has to be safely discharge after a high voltage set. An emergency button on surge generato shall be provided to disconnect all equipments. All equipments shall be discharge on supply failure or disconnection of the unit. Make - CSD Instruments , Megger, Techno, Telemetrics. Note : The contractor will train two persons which has to be nominated by GE/ Engr-in-charge about all functions of fault locator machine and one person should be deployed at their ends to attend any problems which occurs in machine, and the individual will be present in office/site within days after intimation from office till six month after completion of work.
