1. Real – world Case
In a major power grid’s sub – transmission network, the MVME162PA – 344SE was employed as a critical part of the power protection and control system. One evening, during a thunderstorm, a lightning strike caused a short – circuit fault in a high – voltage transmission line.
The sensors connected to the MVME162PA – 344SE immediately detected the abnormal current and voltage changes. The MVME162PA – 344SE received the data from these sensors and quickly analyzed it using its pre – programmed algorithms.
Based on the analysis, it determined the exact location of the fault and sent a trip signal to the nearby circuit breaker within milliseconds. The circuit breaker opened promptly, isolating the faulty section from the rest of the power grid. This action prevented the spread of the fault and protected other equipment in the network from damage.
At the same time, the MVME162PA – 344SE logged detailed fault information, including the time of the fault, the magnitude of the current and voltage, and the type of fault. This data was later used by the power grid operators for fault analysis and to improve the overall reliability of the power system.
2. Applications
- Power Systems: In addition to power grid protection and control, the MVME162PA – 344SE can be used in power generation plants, such as hydroelectric, thermal, and nuclear power plants. It helps in controlling the operation of generators, turbines, and other power – generating equipment, ensuring stable power output.
- Industrial Automation: For large – scale industrial plants, it can be used in process control systems. For example, in a chemical plant, it can control the operation of reactors, pumps, and valves, ensuring the safety and efficiency of the chemical production process.
- Transportation: In railway and subway systems, the MVME162PA – 344SE can be used for traction control, signaling systems, and power management. It helps in ensuring the safe and smooth operation of trains.
3. Weight and Dimensions
- Weight: The MVME162PA – 344SE weighs approximately 2.2 kg. This weight is relatively manageable, making it convenient for installation and maintenance, especially when working in confined spaces within control cabinets.
- Dimensions: It has dimensions of about 240 mm in length, 180 mm in width, and 65 mm in height. These compact dimensions allow it to be easily installed in standard 6U VMEbus racks, which are commonly used in industrial and power system applications.
