The Hioki PQ3100-94 is a Portable Power Quality Analyzers used for measuring single to three-phase lines with a high degree of precision and accuracy. The PQ3100-94 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 PQ310094 also comes equipt with four 6000 Amp current clamps and other accessories

AC/DC power measurement and power quality monitoring

DC measurement is required when dealing with renewable energy sources such as solar power, which are entering into increasingly widespread use. When used with AC/DC auto-zero current sensors, the PQ3100-94 can measure AC and DC currents while maintaining accuracy over extended periods of time.

Easy, accurate connection and configuration with the Quick Set function, which guides the user through measurement procedures

The PQ3100's Quick Set function provides easy-to-understand guidance for measurement procedures. By using this function, customers can reliably connect and configure the instrument, a process which if not completed properly can lead to measurement errors.

More accurate analysis of issue causes thanks to the ability to record 11 seconds surrounding anomalous events

In the event of an instantaneous power outage or a swell, in which the voltage rises abnormally, the PQ3100-94 can record waveforms for 1 second before and 10 seconds after the anomaly. Whereas the legacy Hioki PQA PW3198 only records these pre- and post-event waveforms for 1 second, the new PQA lets engineers analyze the causes of anomalies using waveforms captured over a longer period of time.

Robust support for customers' analytical work thanks to a full-featured PC application

Reflecting the fact that customers often use computers to analyze measurement data and create reports, the PQ3100-94 ships standard with PQ ONE, a new, dedicated application. PQ ONE augments the functionality provided by Hioki's legacy PC application with new statistical functions that display the number of events detected by date and time. In this way, the application makes it easier to discover anomalies that occur during specific times of day or on specific days of the week.

Extensive line of current sensors to accommodate a diverse range of customer needs

Hioki offers 10 types of current sensors for use with the PQ310094 in different applications, including AC current sensors, AC flexible current sensors, AC/DC auto-zero current sensors, and AC leak current sensors. In this way, the instrument can accommodate a diverse range of customer measurement needs.

In addition, the PQ3100-94 can supply power to AC flexible current sensors (CT7044, CT7045, and CT7046) as well as AC/DC auto-zero current sensors (CT7731, CT7736, and CT7742). This capability eliminates the need to provide a separate AC adapter or battery for each sensor, simplifying wiring in the vicinity of the instrument and enabling long-term measurement.

CAT III (1000 V) safety and an operating temperature range of -20°C to 50°C

The PQ3100-94 is designed to support CAT III (1000 V) and CAT IV (600 V) environments. (The legacy PW3198 supports only CAT IV 600 V environments.)

In addition, the PQ3100-94 improves the PW3198's operating temperature range of 0°C to 50°C, extending it to -20°C to 50°C to enable measurement in even low-temperature environments.
