- Electric Parameter Measurement: You can consider using a power meter or energy meter that supports full electric parameter measurement of a three-phase circuit with an external current transformer. These devices can measure voltage, current, power, and other parameters accurately.
- Extremum Recording: Look for a device that can record the extremum (maximum or minimum) values of voltage, current, and power for the current month and the previous month. This will help you analyze the energy consumption patterns and identify any abnormalities.
- Real-time Monitoring: Choose a system that can provide real-time measurements of current and power demand. This will allow you to monitor the electrical load and make adjustments if necessary.
- Alarm Outputs: Ensure that the system supports alarm outputs for over-voltage, over-current, phase failure, and other abnormal conditions. This will help you promptly identify any potential issues and take appropriate actions.
- Energy Measurement: Look for a device that can calculate the four-quadrant electric energy consumption. Additionally, consider a system that supports multi-rate electric energy measurement for a 12-month period. This will help you analyze your energy consumption patterns and manage your electricity usage effectively.
- I/O and Communication: Consider a system that provides 2 channel switching inputs, 2 channel switching outputs, and RS485 communication. These features will allow you to interface with other devices or systems and integrate the energy measurement into your existing infrastructure.
