Application Fields
The XPHS-1102AZ is primarily used in electrical distribution and industrial power management for:
- Power Factor Correction: Providing the phase angle data required for automatic capacitor bank switching.
- Synchronizing Systems: Monitoring the phase relationship between two power sources before paralleling.
- Load Analysis: Assessing the reactive power components in large industrial motor circuits.
- Substation Automation: Sending phase data to SCADA systems and remote terminal units (RTUs).
- Research and Development: Monitoring phase shifts in experimental electrical machinery.
Product Usage Instructions
- Safety Check: Ensure all current transformer (CT) and potential transformer (PT) circuits are de-energized before making connections. Never open-circuit a live CT.
- Wiring: Connect the voltage input (PT) to the designated voltage terminals and the current input (CT) to the current terminals. Ensure the polarity (K/L or P1/P2) is correct for accurate phase sensing.
- Output Connection: Connect the DC output terminals to your PLC, meter, or data logger. Observe correct polarity to prevent measurement errors.
- Zero/Span Adjustment: If the unit has accessible potentiometers, perform a fine-tune calibration at zero phase (resistive load) and full-scale phase shift using a calibrated reference meter.
- Environment: Install the transducer in a clean, dry environment within its rated operating temperature range to maintain specified accuracy.
Product Technical Description
The XPHS-1102AZ utilizes an electronic phase-detection circuit to determine the time difference between the zero-crossing points of the voltage and current waveforms. This time-interval is then integrated and filtered to produce a highly stable DC voltage or current that is directly proportional to the phase angle (ϕ). Unlike simple power factor meters, this transducer provides a linear output over the entire phase range, making it ideal for systems where the load can be both inductive and capacitive. Its robust internal isolation protects sensitive downstream electronics from high-voltage transients common in industrial power grids.
Q&A (Common Questions)
Q: Can this unit measure the phase difference between two separate voltage sources? A: Typically, the XPHS-1102AZ is a Voltage-Current (V-I) phase transducer. For Voltage-Voltage (V-V) phase comparison, a specialized synchro-transducer or dual-voltage input model may be required.
Q: Does the accuracy vary with the magnitude of the input current? A: The transducer is designed to maintain its accuracy class within a specified range of the rated current (usually 10% to 120% of the nominal input).
Q: Is the output affected by harmonic distortion in the power line? A: Toshiba transducers include internal filtering to minimize the impact of harmonics, though extreme distortion (THD > 10%) may result in a slight decrease in precision.
Q: What is the response time of the DC output? A: The typical response time is between 200ms and 400ms, which is sufficient for most industrial monitoring and steady-state control applications.
