What Are the Differences Between Active Power Transducers of Different Phases?

Active power transducers are typically categorized by phase into single-phase, three-phase, and, less commonly, two-phase. Different phase active power transducers have different measurement accuracy and application ranges.

Single-phase active power transducer

They are relatively simple in design, processing only a single voltage and current input. They measure the active power within a single AC phase by sensing the voltage and current of that specific phase. Because they require less measurement data, they offer the highest measurement accuracy. Single-phase active power transducers are primarily used to monitor residential loads and small electronic devices.

Two-phase active power transducer

In a two-phase system, there are two independent alternating current (AC) voltages, each 90° out of phase with the other. Two-phase active power transducers are designed to measure active power in systems with two independent phases. They are primarily used in traditional power systems, specialized machinery, and experimental equipment.

Three-phase active power transducer

They are primarily used to measure power in three independent but related phases, typically 120° out of phase with each other. Designed specifically for industrial or commercial loads powered primarily by three-phase power, three-phase active power transducers are crucial for accurate power monitoring in large three-phase electrical systems, as the total power of the system is the sum of the power of each phase.

This section introduces the characteristics and application ranges of active power transducers for different phases. On OFweek Mall, you can find a wide selection of single-phase, two-phase, and three-phase active power transducers in a wide range of specifications, each with detailed specification sheets.

True RMS Voltage Transducers can be categorized as single-phase, three-phase, and multi-phase based on their application and output signal type. The phase of a true RMS voltage transducer refers to the angular relationship between the voltage and current waveforms in an AC circuit. Different phases also have different application areas. Single-phase true RMS voltage transducers: Operate using a single AC waveform, stepping up or down the voltage based on lower power requirements. They have a relatively simple structure and a relatively low cost. They can measure the RMS voltage of a single AC line and are primarily used to monitor the supply voltage quality in residential environments, small offices, and household appliances and lighting systems.
