MV-Short circuit indicator For cable networks and overhead lines SICAM short circuit indicator for cable networks The efficient operation of modern distribution grids requires being able to detect and locate faults quickly, packing them into messages and providing them for subsequent processing. With the SICAM short-circuit and earth fault indication systems, Siemens now offers devices suitable for fault detection and indication in mediumvoltage networks. SICAM FCM (Feeder Condition Monitor) • • Use of low-power sensors and high-quality measurement technology with high measuring accuracy Alternative: Version for connection to capacitive voltage test systems Direct voltage measurement in low voltage networks Usable in grounded, isolated and compensated distribution systems Cost savings thanks to precise and fast fault location SICAM FPI (Fault Passage Indicator) • • For the detection of phase- and earth faults in radial or open ring cable networks Does not require auxiliary voltage - self-sustaining, maintains its functionality thanks to the integrated lithium battery, even after the main supply is triggered Meets the safety standard IEC 61010-1 Isolated, plastic fiber-optic connections between sensors and SICAM FPI are noise immune

SICAM Short circuit indicators for overhead lines The short-circuit and earth-fault monitoring system SICAM FSI (Fault Sensor Indicator) detects and reports phase faults and earth faults in the medium-voltage overhead line network. The mounting by means of an insert into the line by means of an insulating rod is very easy. The SICAM FSI uses the encrypted wireless network ZigBee to communicate with the SICAM FCG (max. reach 100 m). SICAM FSI (Fault Sensor Indicator) • Operating voltage: 3,3 to 66 kV • Precise fault localization for overhead lines • Fault indication by flashing light and indication...
