The key to continuously improving power supply is essentially in depth knowledge of the relevant conditions of the local network. This is achieved through the use of all available sources connected to the system. Siemens offers a complete portfolio for network monitoring, power quality recording, fault recording, phasor measurement and system software application. Power quality and measurements supports power supply utilities and consumers with solutions required for the precise measurement, recording and reporting of the necessary distribution network data used to continuously determine, adapt and improve the power quality.
SICAM FCM the finger on the pulse of your distribution Network
SICAM FCM (Feeder Condition Monitor) is a short circuit and ground fault indicator with direction indication which uses protection algorithms and latest low power sensor technology according to IEC 60044, yielding top results, particularly in isolated or compensated distribution networks.
SICAM FCM offers comprehensive measured values to monitor the load of distribution network components thus providing accurate data on the network condition. Live values, e.g. of a transformer operated at overload, allow countermeasures to be taken in time such as load shedding or reducing the feedback power in the affected network segment. In order to correctly evaluate the condition of the distribution network, SICAM FCM provides all relevant data via a Modbus RTU interface.
SICAM Fault Passage Indicator (FPI) is a device that is used for detection and signalling of short circuit and earth-fault on medium voltage cable networks.
4 external current sensors detect the phase faults (R, Y, B) and earth-fault (E).
The current sensor detects phase fault and earth-fault current based on the set current threshold detection and communicate to SICAM FPI via an optical signal.
By using the rotary switch available on the individual sensor, you can set the fault current threshold for phase sensors from 200 A to 1200 A (Type 1 Series), 200 A to 800 A (Type 2 Series) and for earth sensor from 10 A to 100 A (Type 1 Series), 40 A to 300 A (Type 2 Series).
When the current exceeds the set threshold level, the current sensor provides an input via plastic fibre-optic cable to SICAM FPI. In this condition, the corresponding LEDs blink. In normal operating condition, there is no LED indication.
SICAM FPI is used as a fault detection and indication unit. SICAM FPI is used in the feeder and distribution automation of secondary medium-voltage systems that ranges from 10 kV to 36 kV.
The guardian for your overhead line networks (3.3 to 66 kV 50/60Hz)
Utilizing the full range of benefits of distribution automation in overhead line networks requires reliable locating and signaling of earth faults and short circuits in overhead line networks. With SICAM FSI (Fault Sensor Indicator), Siemens now offers a fault detection device for MV overhead line networks.
SICAM FSI is available in 2 versions:
The large-size display of the initial commissioning year on the device enables operating personnel to see when the battery is due for changing while remaining on the floor.
The SICAM Fault Collector Gateway (FCG) device receives both the load current values and distribution line faults via the SICAM Fault Sensor Indicator (FSI)
The received information status and events are transmitted to the control center based on the IEC 60870-5-104 protocol or to the Siemens FLiC service using the XMPP protocol. The fault detected by SICAM FSI is communicated to SICAM FCG via short-range radio (SRR) communication within a distance of 100 meters.
SICAM FCG provides 6 binary inputs and 3 binary outputs. SICAM FCG can be configured and diagnosed locally using the Web GUI by connecting to a PC or laptop computer or remotely via General Packet Radio Service (GPRS).
The SICAM FCG has a plastic housing and it is strongly recommended to mount it within a metal cabinet for additional protection. The Global System for Mobile Communications (GSM) and short-range radio antenna are mounted outside the metallic cabinet. SICAM FSI firmware and parameters can be updated from the SICAM FCG.
SICAM FCG Web GUI allows you to configure the parameters, display error and event log, upgrade of firmware, and download the configuration.
