The efficient operation of modern distribution grids requires quick fault detection, message packing and provision for further processing. The SICAM Fault Passage Indicator (FPI) is one component for that. The FPI is used for phase fault detection and indication and for detection of earth faults in radial or open ring medium-voltage cable networks. 4 external current sensors detect phase faults (L1, L2, L3) and earth faults (E). The current sensors detect phase fault and earth fault currents based on the set current threshold detection, and communicate them to SICAM FPI via an optical signal. The rotary switch on each sensor is used to set the fault current threshold for phase sensors from 200 A to 1200 A (Type 1), 200 A to 800 A (Type 2) and for earth sensors from 10 A to 100 A (Type 1), 40 A to 300 A (Type 2). If the current exceeds the set threshold level, the current sensor will send an input to SICAM FPI via plastic fiber-optic cable. In this condition, the corresponding LEDs are flashing and the binary contacts are picking up. In normal operating conditions, there is no LED indication.

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: 6MD2314-1AB10 - without communication: The faults are signaled directly at the device by LEDs. Depending on the fault state, a specific flashing light is generated. 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 using the standardized telecontrol protocol IEC 60870-5-104 or via XMPP.
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.

Feeder Condition Monitor - Digital short circuit indicator with measuring function for medium voltage switchgears. The key to continuous improvement in the power supply is accurate knowledge about the relevant circumstances of the local energy supply system. Functionality: The SICAM FCM (Feeder Condition Monitor) is a phasefault and ground-fault indicator with directional indication that operates with protection algorithms and low-power current transformer technology as per IEC 60044-8/ IEC 61869-10 or the conventional 1 A/5 A instrument transformers. As an alternative, the SICAM FCM can also be connected using a capacitive voltage tap, thus effecting economical directional fault detection in the cable network. The SICAM FCM additionally offers the possibility of providing up-to-date measured values via the integrated Modbus RTU interface, thus ensuring a precise assessment of the distribution system. Cost-effective measuring device for use in Low voltage switchgears. The SICAM FCM (Feeder Condition Monitor) also performs well as a low-cost power meter in a low-voltage power system. It is optimized for flush mounting in low-voltage switch bays because of the low height.
Ensuring power quality in a phase of energy transition
Increasing power feed-in from renewable resources poses new challenges for municipalities and distribution system operators
The stable supply of electric power is any grid operator’s top priority. To avoid fluctuations in power quality and prevent disturbances, grid monitoring, control, and automation systems need to be adapted and optimized across all voltage levels.
Maintaining control of distributed power producers
Ensuring grid stability is becoming increasingly complex
The vast number of small distributed power producers calls for new strategies to ensure consistent power quality. Identifying, locating, and eliminating disturbances and faults as well as the flexible, quick balancing of power production and load consumption require integrated hardware and software solutions that work smoothly together.
Intelligent technologies for stable grids
Automation solutions and remote control technology enhance the reliability of distribution grids
Despite every effort, grid disturbances and faults can never be entirely eliminated. This is why control room personnel must be enabled to work quickly and effectively to resolve problems in a targeted manner. Comprehensive automation and remote-control solutions optimize these capabilities.
Efficient grid expansion
A combination of robust technology and digital innovations leads to increased efficiency
Maintaining or even increasing grid performance is becoming ever more challenging. With growing efforts, expenses grow as well. Innovative technologies and smart data usage can help municipalities and DSOs to master these challenges and to increase their competitiveness.
Keeping your grids up and running
Using sophisticated tools and solutions for fast grid restoration
Unplanned outages cannot always be avoided. Flexible solutions for local and remote monitoring enable the fast and efficient restoration of cable grids and overhead lines.

Siemens SICAM DISTO Software for detection and storage of fault records
An important function of digital protection is to store disturbance records for more accurate analysis of critical events in the grid. As the memory for such records is limited in the relay it has shown convenient to extract them by use of standardized communication and store them on a hard disk on station level for further use.
Serial communication of digital protective devices to Substation Control Systems has been standardized and published as IEC standard protocol 60870-5-103. Recently the new standard for power utility communication IEC 61850 has added much more flexibility and performance to data exchange with different IEDs.

IEC standard protocols employed in modern substation control enable homogeneous, vendor-neutral total solutions and offer optimum investment security for the operator. Even with standardized protocols, the analysis or simulation of the behavior of the employed devices is a daily requirement in the operation and installation of substation control systems. The SICAM Protocol Test System provides this functionality.Simulating individual or several devices simplifies process-es, especially when planning systems. Importing the IEC 61850 standard files enables the user to simulate device behavior and to streamline test and com-missioning procedures. Vendor-neutral, comprehensive analysis features help to resolve errors or faults of individual devices. The SICAM Protocol Test System assists system planners and operators to simplify their daily work and will become an indispensable tool.
Characteristics and technical highlights
Although the standards themselves are long past the development stage, problems still tend to arise during implementation of projects. These are due to slight differences between systems (resulting from varying interpretations of the standard, specific features of the project, etc.) and can have significant cost implications. In addition, in many cases operators will need to test equipment early on in the course of a project although some of the system components or devices are not yet available at that time.
