SICAM FSI: Short-circuit indicator

Why Short-circuit indicator for overhead lines – SICAM?

With SICAM FSI (Fault Sensor Indicator), Siemens offers a fault detection device for MV overhead line networks. This device ensures higher network availability by quickly and reliably locating and signaling earth faults and short circuits. Its maintenance-free design with a 10-year battery life provides a highly user-friendly and cost-effective solution. SICAM FSI is available in 2 versions: 6MD2314-1AB10 – without communication: The faults are signaled directly at the device by LEDs. 6MD2314-1AB11 - with communication: In addition to local LED display, earth faults and short circuits are transferred to a gateway (SICAM FCG) via a secured radio connection. SICAM FCG (Fault Collector Gateway) establishes the connection to a higher-level control center via GPRS and sends the messages to the control center.

Key benefits

Reduce maintenance and energy use

The SICAM FSI is maintenance-free – just change the battery after 10 years. Self-sustained sensors reduce the energy consumption of the device, enhancing the service life of the supply battery.

Lower downtime

Quick fault detection exact fault localization and information to maintenance teams for less downtime and higher availability of overhead line networks.

Configure the device easily

Enjoy quick and easy device configuration with QR code on SICAM FSI and a web browser rather than DIP switches.

FEATURED CAPABILITIES

Features & functions

Trip threshold setting range 75 A to 1500 A

Inom setting is user configurable from 50 to 500 A enabling closer coordination with the upstream protection system for the network. Trip time is user configurable between 1.5*Inom and 3*Inom (in steps of 0.5 Inom).

∆I trigger setting 5 A to 160 A

The rate of change of current (∆I) setting is user configurable in steps of 5 A up to 80 A, 120 A, 160 A.

Configuration

The SICAM FSI – 6MD2314-1AB10 - can be parameterized using “FSI Web Configurator” software. The SICAM FSI- 6MD2314-1AB11 - can be parameterized via the SICAM FCG over the wireless Interface.
