Description
The active and reactive combined transducer is an integrated measurement device that can monitor the active and reactive power in the power system at the same time and provide comprehensive power parameter data. The active and reactive combined transducer can reduce the installation space and wiring complexity, and reduce the cost of multi-sensor deployment. The active and reactive combined transducer is calculated based on the voltage and current signals at the same time to avoid errors caused by time differences.

Wiring
Tips: Advantages of active and reactive combined power transducer
- Save space and cost: Measure active and reactive power simultaneously with a single device, reducing the need to install multiple independent transducers, hardware costs and wiring complexity. Suitable for scenarios with limited space (such as distribution cabinets, and compact equipment).
- High data synchronization: Calculate active and reactive power based on voltage and current signals at the same time point, avoiding data asynchrony caused by the sampling time difference of split sensors.
- Easy maintenance: Only a single device needs to be calibrated, reducing the workload of calibrating split transducers one by one. The centralized design facilitates monitoring and diagnosis, reducing maintenance difficulty.
