Product Information OverviewHIOKI | Power Quality Analyzers & Power Loggers

The critical importance of electrical power in today's society necessitates daily maintenance and management to ensure that products don't occur. 

When they do, engineers face the need to analyze the cause, such as an equipment failure or abrupt surge in demand, as quickly as possible. From measurement to long-term recording and analysis, Hioki's tools support reliable power analysis with superior operability for efficient power operation, troubleshooting, and predictive maintenance.

Efficient operation of electricity


Reduce costs through efficient operation of electricity
  • Power saving activity, leakage current prevention, electricity operation improvement, etc.
  • Energy cost calculation
  • Check for discrepancies with an electricity meter

Predictive maintenance & power survey


Reduce the impact of poor power quality on asset costs
  • By monitoring the quality of the power supply on a long-term or regular basis, it is possible to detect signs of trouble and prevent it from happening in the first place.
  • By monitoring the quality of the power supply on a long-term or regular basis, it is possible to detect signs of trouble and prevent it from happening in the first place.

Troubleshooting


Find the cause of equipment problems, diagnose and take countermeasures
  • Conduct power quality investigations at sites where problems such as equipment failure or malfunction are occurring.
  • Check the condition of before and after the installment of an electrical facility.

Resolving disputes

  • Check the condition of before and after the installment of an electrical facility.

 

PQ3198

Power Quality Analyzer - Advance

FEATURES

  • Class A compliance under international standards
  • Basic voltage measurement accuracy of ±0.1%
  • High Voltage, wideband performance
  • Two-circuit measurement
  • Simple inverter measurement
  • 400Hz line measurement
  • GPS time synchronization
  • Extensive array of event measurement parameters
 


Investigate power supply anomalies

Investigate the causes of equipment failures and malfunctions, including issues that are difficult to identify, such as when a device causes a properly-functioning piece of equipment that is connected to the same power outlet to experience a voltage drop.

Verify the quality of power from a solar power system

Check fluctuations in the output voltage of a power conditioner in a solar power system along with flicker and transient voltages. You can also measure fluctuations in the frequency of the grid interconnection and fluctuations in the harmonic voltage and current components of the system’s output

Verify the quality of power supplied by an EV rapid charger

Since the PQ3198’s fourth voltage channel is isolated from its first three voltage channels, the instrument can measure power and efficiency across two separate circuits. For example, you can verify the quality of the input (AC) and output (DC) of an EV rapid charger while simultaneously measuring power and efficiency between input and output.

 

PQ3100

Power Quality Analyzer - Standard

FEATURES

  • Simple setup with QUICK SET
  • Record event waveforms of up to 11 sec. in duration
  • 8 hours of battery operation
  • 200 ms and 600 ms data save capability
  • CAT III (1000 V)/CAT IV (600 V)
  • Display event statistics
  • Demand recording
 


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.
