Our Know How
The PDM system has been designed to capture, measure and log the ultra high frequency (UHF) signals generated by partial discharges within gas insulated switchgear (GIS). Couplers are distributed throughout the switchgear to pick up signals in the range of between 500 MHz to 1,500 MHz. These signals are routed to the PDM where the signal is detected, amplified and stored for diagnosis. From the stored data it is possible to determine the magnitude, probable location and type of any partial discharge activity within the GIS.

The SI(emens) PROTEC(tion) devices lead the way in integrating protection, control, measurement, and automation functions in one unit.

Thanks to the homogenous system platform and extensive experience of more than a million successfully operating devices in the field worldwide SIPROTEC enjoys top recognition among users. SIPROTEC is the industry standard for digital protection technology today.

  • In many fields of application, all secondary technical functions can be carried out using just one device. This lowers investment costs, reduces installation work in every respect, and increases system availability.
  • The implementation of the international IEC 61850 standard has played a significant role in forming a consistent and future-proof basis for all protection, communications, and control functions.
  • The trendsetting system architecture places communication firmly under the protection engineer's control. Powerful, flexible, and above all reliable communication is the most important prerequisite for distributed and decentralized systems such as smart grids.
  • The implementation of IEC 61850 edition 2 unfolds the entire potential of this standard by optimally supporting operational needs and making handling easy.

SICAM PAS is developed in accordance with selected security standards and meets modern demands placed on safe communication. Asymmetric encryption enables tap-proof communication connection to higher-level control centers with IEC 60870-5-104 and DNP V3.00 via TCP/IP.
SIMATIC WinCC (TIA Portal) is part of a comprehensive, integrated engineering concept which offers a uniform engineering environment for programming and configuration of control, visualization drive solutions and motor management. This engineering framework is a milestone in software development and represents the consistent further development of the TIA concept. WinCC in the TIA Portal is the software for all HMI applications ranging from the simplest operation solutions with Basic Panels to SCADA applications on PC-based multi-user systems. The range of solutions is thus increased significantly compared to the predecessor product, SIMATIC WinCC flexible. SIMATIC WinCC V7 is still available for more complex applications with Plant Intelligence solutions or redundant architectures, while WinCC Open Architecture addresses solutions with highly customer-specific adaptation requirements, including on non-Windows platforms.


  • Innovative configuration interface based on the latest software technologies
  • Comprehensive library concept for user-definable objects and faceplates
  • Intelligent tools for graphical configuration and mass data handling
  • Start/stop sequences
  • Communication with remote stations and control centers

Design and functions Compared to WinCC flexible, which has set the standards in engineering for years, configuration efficiency has been further increased, particularly if further TIA components such as the SIMATIC S7 Controller are part of the automation solution. The perfect interaction with STEP 7 in the TIA Portal prevents multiple entries and guarantees consistent data managementat all times

Perfect interaction in the engineering framework The design of the software editors in the TIA Portal is based on a shared layout and shared navigation concept. The configuration of the hardware, logic programming, parameterization of a frequency converter, or the design of an HMI screen - each environment has the same editor design, which is specifically designed for intuitive use to save time and costs.

Configuring with libraries and faceplates The library concept of the TIA Portal is not limited to the supplied program blocks or faceplates. With the TIA Portal, the user can create his own libraries of many various parts of the engineering objects, which can be easily reused.

Intelligent tools for efficient configuration Time-saving configuration means: delegating tasks. SIMATIC WinCC supports the project engineer with wizards for routine tasks and a lot of sophisticated tools and functions that ensure excellent results in shortest realization time.

SICAM RTUs - Family members
The strongest member of the product family is extremely flexible and powerful thanks to the modular, consistent SICAM system architecture. Automation, telecontrol, and communication functions can be easily combined in full compliance with IEC 61850.
SICAM A8000 Series
With the increasing number of prosumers, the power grid is changing into a bidirectional network where load flow control is crucial. The cost-effective SICAM A8000 Series has been designed to manage the effects of decentralized power feed-ins and reduce network losses.
The SICAM TM combines cost-effectiveness and complexity in an optimal manner. This family member may be used as a simple data concentrator or protocol converter, but its modularity allows expanding this automation unit to monitor and control hundreds of field devices.
With its scalable size, SICAM 230 provides a convenient, transparent and open interface between the operator and the process, especially for utility and industrial companies. Its wide range of seamless, scalable system solutions – from display systems to redundant control center systems – is ideally suited to perfectly map and display your plants with the required depth and technical functionality.

Universal access: the Client-Server Concept, with redundancy Thanks to the network-wide client-server concept of SICAM 230, you can access and process central functions such as alarm and sequence of event lists, archiving, acknowledgments and configuring from any workstation. The SICAM 230 redundancy concept is based on two servers working in parallel, and which are continually being synchronized through the network link. This ensures that messages, fi le entries, derived counters, variable identifiers, trend memories and many other data are brought up-to-date.

Open to all: communications interfaces in SICAM 230 Automation systems such as SICAM 1703 can be interconnected serially (IEC 60870-5-101) or through a LAN or WAN (IEC 60870-5-104). The open interfaces in SICAM 230 equip the system for future standardization trends in the automation or IT sector. What’s more, additional PLC servers (such as Profi bus FMS, SAIA etc.) are available for standardized remote control connections.

Everything under control: alerting functions and event management Use SICAM 230 to adapt your alerting functions and event management perfectly to your application through variable definitions and complex filter conditions available for the output. Flexible reaction matrixes with standardizable processing objects are available to assist you. The output can be issued in the form of reports, open and closed logs or as an export in standard fi le formats. In the event of a breakdown, monitored image hierarchies guide your operating personnel from the overview image to the acknowledgment-capable alarm in the detail process view.

Reliable trend recognition: The SICAM 230 Trend Curve Module The trend curve display feature in SICAM 230 gives you a fast and precise overview of current developments derived from the evaluation of online and archival data.

Logs, wherever and however you need them The SICAM 230 Log Generator generates closed logs based on online and archival data in a simple and convenient manner. This includes even complex logs with a diversity of layout and computational requirements, which can be output on-screen, as a file, or as a print-out.

Error-free configuring: SICAM 230 Project Manager In addition to the object-oriented, menu-driven parameterization with the graphical user interface, you’ll fi nd many other convenient tools in the SICAM 230 Project Manager. These include graphics import, import/export of the data model, copy and alignment functions, zoom, online help, etc. The data model is generated and maintained with the OPM II object-oriented process data manager as part of the TOOLBOX II.
