New HIOKI Power Quality Analyzer

Introducing the New Hioki 3198 Power Quality Analyzer with Advanced Functionality and Performance to Satisfy International Power Quality Standards

(March 2011, Nagano, Japan) HIOKI E.E. CORPORATION is pleased to announce the launch of the new 3198 power quality analyzer. The instrument, which complies with the IEC 61000-4-30 Ed. 2 Class A international standard on power quality measurement, provides unparalleled power quality measurement capability.

Need for Power Quality Measurement

As the number and variety of power electronics devices increases, issues such as device malfunctions and failures caused by power supply problems are becoming more common. To address these issues effectively requires detailed knowledge about their causes, but obtaining such knowledge is an extremely time-consuming proposition due to the diverse array of parameters that must be investigated and the high level of expertise required to do so. By using a power quality analyzer, it is possible to discover the underlying causes of these hardware issues precisely and efficiently.

Adding to the complexity of the situation is a recent trend toward more widespread use of distributed power sources such as solar power, wind power, and cogeneration systems. Initiatives to put in place smart grid technologies (which form the basis of the next-generation power distribution network) are also proceeding apace, with increasingly complex power transmission systems driving up demand for more rigorous monitoring.

Furthermore, there has been little progress in improving the power environment in developing nations such as China and India compared to Japan and the U.S. or Europe due to the failure of infrastructure development to keep pace with economic growth. Consequently, power supply problems are an everyday occurrence.

In this way, the need for power quality measurement continues to increase with each passing year, providing the ideal environment for the PW3198 to leverage its capabilities.

HIOKI 3198 Features:

  • Compliance with the IEC 61000-4-30 Class A international power quality standard and dramatically improved measurement reliability

    Compliance with the IEC 61000-4-30 Class A international standard on power quality measurement, which stipulates the most stringent requirements in the field, points to the PW3198’s unparalleled functionality and reliability. To comply with the standard, the instrument delivers basic voltage measurement precision of 0.1%, an improvement of 200% over the previous model.

  • Simple configuration function for intuitive operation

    The PW3198 incorporates a user-friendly configuration function that automatically selects the necessary measurement items once the user has chosen a measurement pattern, for example abnormal voltage detection. This capability eliminates the need for the user to configure a series of complex settings, significantly improving the instrument’s convenience.

  • Extended measurement capability thanks to flexible use of SD cards (2 GB card bundled with product)

    The need for continuous monitoring in power quality measurement applications makes extended recording capability a must. The PW3198 ships standard with a 2 GB SD card that allows continuous measurement for up to 55 weeks.

  • Improved safety thanks to CAT IV 600 V compliance

    Whereas the PW3198’s predecessor POWER QUALITY ANALYZER 3196 offered a CAT III 600 V safety level as defined by IEC 61010, the new PW3198 complies with CAT IV 600 V requirements. The higher level of protection enables the instrument to safely measure incoming power lines.

    The New World Standard for Power Quality Analysis, with Recording & Analyzing

  • Verify power problems in accordance with the IEC61000-4-30 Class A standard

  • High Accuracy and continuous gapless recording (V:±0.1% of nominal voltage, A and W:±0.2% rdg. ±0.1%

  • CAT IV 600V – safe enough for incoming power lines

  • Broadband voltage range lets you measure even high-order harmonic components of up to 80

  • Wide dynamic range from low voltages up to 1300V (3P4W line-to-line voltage)

  • Maximum 6000V transient overvoltage up to 700kHz

  • LAN, USB and SD card interfaces

  • Optional GPS BOX for synchronizing multiple devices

    Note: You can measure a voltage use with the main unit alone. Optional current sensor is necessary to measure current or power parameters. Use Model 9624-50 PQA-HiVIEW PRO (version 2.00 or later) with a PC to analyze the data collected to SD card.


Power Quality Analyzer Includes: L1000 Voltage Cables,
AC Adaptor, Battery Pack, 2GByte SD Card Z4001
