How to Choose an Active Power Transducer?

图片
When purchasing an active power transducer , you should fully consider your application's requirements. Here are a few common factors to consider: Power Measurement Type Single-Phase or Three-Phase: Choose based on your power system's power load. Balanced vs. Unbalanced Load: For unbalanced loads, you may need a sensor with per-phase measurement capabilities. True RMS or Average Response: For distorted waveforms (e.g., from VFDs, UPSs, inverters), choose a true RMS or DSP-based device. Electrical Parameters Voltage Range: Check if the sensor supports standard system voltages (e.g., 120V, 230V, 400V, etc.). Current Range: Determine whether you will be measuring directly or through a CT (current transformer). Select the input range accordingly (e.g., 0-5A, 0-1A). Frequency: Ensure compatibility with your system frequency (50Hz, 60Hz, or variable frequency in inverter-driven systems). single phase active power sensor Accuracy and Performance Accuracy: Typically ±0.2% to ±1%, depen...

What is an Active Power Transducer?

 An  active power transducer  is an electrical measuring device primarily used to measure the active power in a circuit. It measures the voltage and current in the circuit and then uses an internal electronic multiplier to calculate and output the actual work done. The main calculation formula is P = V⋅I⋅cosφ. Active power transducers offer high accuracy, excellent stability, and easy integration into control systems. Applications of Active Power Transducers Energy Management Systems Used to measure the actual power consumption of equipment and facilities, assisting in the rational and efficient allocation of energy. Industrial Equipment Monitoring Real-time monitoring of power consumption of motors, pumps, compressors, and production machinery. This provides a reference for optimizing factory processes and reducing operating costs. Detecting abnormal power usage that could indicate overloads, mechanical failures, or process inefficiencies. This helps prevent mechanical f...
