PQ3100
- Measurement functionality and data recording capabilities
- Capture the full picture with a single measurement
- Capture power anomalies reliably
PQ3100 can measure all parameters at once, including power, harmonics, and anomaly waveforms. The instruments also provide simple setup functionality for automatically configuring recording parameters for popular applications.
Area of
Applications
Investigate power supply conditions
Measure voltage fluctuations, equipment capacity, and harmonics before installing new electrical equipment. You can also check whether newly installed equipment is affecting other equipment by repeating those measurements after installation and comparing the results.
Prevent power supply problems
Discover signs of impending problems by repeatedly measuring a component such as an elevator motor on a regular basis. Flexible current sensors make it possible to connect the instrument safely and easily, even in difficult settings involving double wiring, busbars, and crowded distribution boards.
Perform load rejection testing of solar power systems
In load rejection testing, it’s necessary to record transient changes in current and voltage when the system is taken offline. The PQ3100 can record anomalous waveforms for up to 11 seconds (1 second before and 10 after each event). Cursor measurement lets you verify peak values and duration as well.
Power Quality Parameters
measuring
Transient voltages
Capture phenomena characterized by precipitous voltage changes and high peak values caused by lightning or circuit breaker or relay contact issues or tripping.
Voltage swells
Capture phenomena characterized by a momentary rise in voltage, for example due to lightning or power line switching.
Voltage dips
Capture phenomena characterized by a short-duration drop in voltage when a large inrush current occurs, for example due to motor startup.
Interruptions
Capture phenomena characterized by a stoppage in the supply of power, for example when lightning interrupts power or when a power supply short- circuit trips a circuit breaker.
Frequency fluctuations
Capture frequency fluctuations caused when generator operation becomes unstable due to an abrupt increase or decrease in load.
Inrush current
Capture phenomena characterized by a large current that flows momentarily when a device starts up upon receiving power, for example electric equipment and motors.
Harmonics
Capture phenomena characterized by distortions in voltage and current waveforms that are caused by semiconductor control devices.
High-order harmonics (Supraharmonics)
Capture phenomena characterized by distortions in voltage and current waveforms caused by noise components from semiconductor control devices such as those used in electronic device power supplies.
Unbalance
Observe voltage and current waveform distortion, voltage dips, and negative-phase-sequence voltage that occur when the loads connected to individual phases in a 3-phase power supply change or when unstable equipment operation increases the load on a specific phase.
