The Hioki PQ3100 Power Quality Analyzer is designed to measure single to three-phase lines with a high degree of precision and accuracy. The PQ3100 is a comprehensive but easy-to-use power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues.

The PQ3100 offers the QUICK SET function, which makes it easy to generate reliable measurements. Additionally, it can record 11 second event waveforms, yielding extended waveforms when anomalies occur. It can also be used in applications such as load rejection testing of solar power systems.

Measure AC/DC power

Use AC/DC auto-zero current sensors (not included) to measure DC current accurately over extended periods of time. Since the sensors are powered by the instrument, there's no need to set up a separate power supply.

Simple solution to wiring and configuration

The Hioki PQ3100 Power Quality Analyzer provides an intuitive QUICK SET navigation system to simplify the wiring and configuration procedures for measuring a 3-phase system. Connection mistakes such as reversing the direction of the clamp sensor or phase order are automatically detected along with suggestions on how to correct the setup.

Easily manage power quality with PQ ONE bundled application

The free PQ ONE application software for the PQ3100 Power Quality Analyzer lets users analyze captured data in fine detail and create regular power quality management reports with ease and flexibility. Investigate the cause of power anomalies in the comfort of your office using a PC.

Record the power quality of a power grid

The Hioki PQ3100 Power Quality Analyzer measures all power parameters including voltage, current, power, harmonics, and flicker simultaneously along the same time axis, giving it the ability to capture all power anomalies such as intermittent power interruptions, voltage drops and frequency fluctuations while recording the power trend.

Investigate power supply conditions

Measure voltage fluctuations, equipment capacity, and harmonics before installing new electrical equipment. Users 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 (not included) 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 is 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 users verify peak values and duration as well.
