Elektronika, ECFL 30, Active/passive, AC/DC bridge with dual channel TDR for fault location on balanced loaded and unloaded cables
FOUR INSTRUMENTS IN ONE
■ Active bridge for accurate location of faults where the level of disturbing voltages are low
■ Passive bridge for location of faults where the level of disturbing voltages are high
■ Graaf fault locator for accurate fault location on totally water-soaked cable
■ Time Domain Reflectometer to find low impedance faults and splits causing cross talk between pairs
ACTIVE BRIDGE
■ DC Fault Location Methods: Murray, 3 Point, Küpfmüller, Repeated Küpfmüller
■ AC Fault Location Methods: Interruption, Repeated Küpfmüller
■ Resistance difference measurement
■ Loop resistance & Isolation resistance measurement
PASSIVE BRIDGE
■ DC Fault Location Methods: Murray, 3 Point, Küpfmüller, Resistance difference
■ AC Fault Location Methods: Küpfmüller, Capacitive Balance
■ Loop resistance & Isolation resistance measurement
GRAAF FAULT LOCATOR
■ The Graaf method is based on end to end synchronic current measurement
■ It provides accurate fault location when the disturbing DC voltage is high
