6. Real – World Examples

• Office Building Energy Management: In a large office building, the PM803F is installed in the main power distribution panel. It monitors the voltage, current, and power consumption of different floors and departments. By analyzing the energy consumption data collected by the PM803F, the building management can identify areas of high energy consumption and implement energy – saving measures, such as adjusting the lighting and HVAC systems. This has resulted in a significant reduction in the building’s overall energy consumption and cost.
• Solar Power Plant Monitoring: In a solar power plant, the PM803F is used to monitor the output power of each solar panel array. It measures the voltage, current, and power generation of the arrays in real – time. If there is a decrease in power generation in a particular array, the PM803F can detect it immediately and send an alarm to the control center. This allows the maintenance team to quickly identify and fix the problem, ensuring the maximum power generation of the solar power plant.
