According to its importance, electric power system has to be maintained, controlled and protected against possible faults and other abnormal phenomena. The most important parts of every electric power system are electrical rotating machines, especially those involved in the production of electrical energy. Constant increase of the reliability and availability of such machines is of utmost importance. Also, the current practice is to extend periods between planned outages of the machines. Any malfunctions and unnecessary and unplanned outages can cause extensive material damage. The way to alleviate or even prevent such events is implementation of various condition monitoring systems.

Accelerometers and velocity sensors www.koncar-institut.com 4 5 2. Sensors This sensor is used for measurement of bearing temperature. Temperature sensors Pt100, RTD, thermocouple Relative displacement sensor This sensor is used for measurement of shaft relative displacements (orbit). This sensor is used for measurement of generator current. Current measuring sensor Different transducers and sensors are used for measurement of important process values of the power plant (voltage, flow, pressure…). SHCM system can receive and process any analog and digital signal from sensor or transducer which features standard voltage or current signal (on request). Process value transducers 1. SHCM specification Speed sensor This sensor is used for measurement of rotating speed and as a reference for a signal processing. www.koncar-institut.com 6 7 4. Documentation Complete documentation required for system installation, maintenance and usage of the SHCM system. Usual scope of the documentation: • Mechanical documentation (book I) • Electrical documentation (book II) • User instructions (book III) • Initial state records (book IV) • Certificates, test reports… (book V) 3. Software Users can get insight into measuring data through local touch display (local HMI) and through web server (web application). Local visualization enables insight into real-time data, waveforms, vibration spectrums, trends and setup. All screens can be modified according to the Customer’s requests which includes native language. The SHCM system is equipped with a multiuser web server which enables remote access and overview of all system data through standard web browser. This web server provides access to the SHCM system from any desktop or a laptop computer (with Windows or iOS operating system), tablet (with iOS, Android OS…) or smartphone (with iOS, Android OS…). System access is provided without the need for installation of any additional software, using a standard web browser (Google Chrome, Internet Explorer, Mozilla Firefox, Safari …). Web server enables insight into real-time data, vibration spectrums, trends, waveforms and alarms for measurement values increase as well as for fault detection. Local HMI 5. Services Complete services required for system installation, commissioning and usage of the SHCM system. We offer the falowing services: • Consulting services on how to select an optimal monitoring system for new and existing power plants • Installation and commissioning • Staff training • Expert interpretation of the acquired monitoring results We offer the Customer complete services for machine diagnostics.
