CABLE FAULT LOCALIZATION SYNOPSIS
EXTERNAL AGGRESSION SUBMARINE CABLE REMAINS THE PRIMARY CAUSE OF CABLE FAULTS
ACTIVITY SUCH AS FISHING,ABRASION AND DREDGING MAKE UP EXTERNAL AGGRESSION
MOST FAULT CONTINUE TO OCCUR LESS THAN 200M OF WATER DEPTH
CABLE FAULT CAN CLASSIFIED:OPEN ,SHUNT OR OPTICAL FAULT
DEPENDING ON ABOVE CABLE FAULT CATEGORIES THE CABLE FAULT LOCALIZATION WILL VARY
CABLE FAULT CAN BE LOCATED IN PREPARATION FOR REPAIR OPERATION SCENARIOS
POST CABLE INSTALLATION AND REPAIR CERTIFICATION CAN BE ALSO BE PERFORMED
THE LOCATION OF CABLE FAULT IS VERY IMPORTANT FOR COMMUNICATION POWER DISTRIBUTION SYSTEM AND VEHICLES
REFLECTOMETRY METHODS ARE OFTEN USED TO DETECT AND LOCATE CABLE FAULTS
WITH MEASUREMENT OF THE TIME OR PHASE DELAY THE FAULT CAN BE DETECTED AND LOCATED THIS METHODS ARE USED TO DETECT OPEN AND SHORT CKT
IN CASE OF SUB MARINE CABLE L-3 MARIPRO ENGINEERS ARE TRAINED IN VARIOUS METHODS OF FAULT LOCATING TECHNIQUES SUCH AS SINGLE END DC MESUREMENT ,CURRENT-BALANCE METHORDS OR OPTICAL PATH METHODS
STATE-OF THE ART FIBER OPTICS AND METTALIC CABLE FAULT LOCALISATION UTILIZATION LONG-RANGE OPTICAL AND METTALIC TIME DOMAIN REFLECTOMETERS(OTDR AND MTRD) ARE USED BY EXPERIENCED L-3 MARIPRO ENGINEERS
STUDY OF OPTICAL FIBRE TESTING INSTRUMENT USED FOR LOCALIZATION “OFC” FAULT SUCH THAT WITH OTDR(OPTICAL TIME DOMAIN REFLECTOMETER)
RECTIFICATION OF OFC FAULT BY USING SPLICING
TECHNOLOGY PRODUCTS OFFERS A COMPLETE RANGE OF CABLE FAULT LOCATING EQUIPMENT FOR( LV AND HV) CABLES IN POWER PLANTS ,HEAVY INDUSTRYAND DISTRIBUTION SYSTEMS
OCCURANCE OF CABLE FAULT CAN NOT BE AVOIDED DUE TO MANY FACTORS
THERE ARE SOME EQUIPMENTS ARE AVAILABLE FOR CABLE FAULT LOCALIZATION,PIN POINTING AND ROUTE TRACING LIKE SURGE WAVE GENERATORS 16V AND 32V,SENSORS,HEADPHONES AND AMPLIFICATION UNIT,CABLE ROUTE TRACER
SOME ACCESSORIES ARE REQUIDED SUCH AS MEGGERS,DISCHARGE RODS,HIPOT SETS
TECHNOLOGY PRODUCTS MANUFACTURE COMPLETE RANGE OF CABLE FAULT BURNING UNIT WHEN HIGH RESISTANCE FAULT ARE ENCOUNTERED DURING CABLE FAULT LOCATION
