1. PQ3198 Application and Accessory Selection Mind Map
All product model numbers in this tool link to the corresponding RCC Electronics product page. Links open in a new tab.
The PQ3198 is a high-end IEC 61000-4-30 Ed. 3 Class A power quality analyzer. It measures voltage, current, power, harmonics, flicker, swells, dips, interruptions, transients, and 2–80 kHz supraharmonics. Its fourth voltage channel is isolated from the first three, enabling two-circuit measurement or AC/DC input-output comparison.

1. Select by Application
Power quality troubleshooting
For equipment shutdowns, resets, overheating, breaker trips, and unknown power problems: record dips, swells, interruptions, transients, frequency, harmonics, and inrush current.
Long-term monitoring / preventive maintenance
Record trends and events over extended periods; recommended: Z4003 8 GB SD card. For remote field viewing, add the 9642 LAN cable.
Load survey / capacity assessment
Record current, power, power factor, demand, and energy. Select CT7126 / CT7131 / CT7136 or CT7044/45/46 based on maximum current.
Solar, wind, energy storage, and EV charging
Choose CT7731 / CT7736 / CT7742. Use the isolated fourth voltage channel for input/output quality checks and simplified efficiency comparison.
Data center / UPS
Monitor UPS input/output, transients, inrush, harmonics, and continuity of supply. Optional LAN remote management, GPS synchronization, and long-term SD storage are available.
Leakage current investigation
Choose CT7116. Suitable for insulated conductors, rated 6 A AC, and mA-level leakage current investigation.
2. Select by Wiring System and Channel Count
1P2W: typically 1 current sensor.
1P3W: typically 2 current sensors.
3P3W: typically 3 current sensors. Add PW9000 to reduce 3P3W3M voltage connections from six leads to three.
3P4W: 3 phase-current sensors, or 4 when neutral current must also be recorded. Add PW9001 to reduce voltage connections from six leads to four.
Dual-circuit / simultaneous AC and DC measurement:Configure according to the channels used. Up to four current channels are available, and voltage channel 4 is isolated from channels 1 to 3.
3. Select Sensors by Current Type and Range
AC clamp sensors (rigid jaw, accuracy priority)
CT7126:60 A AC, φ15 mm,for small loads and branch circuits.
CT7131:100 A AC, φ46 mm,for general branch circuits.
CT7136:600 A AC, φ46 mm,for distribution panels and main feeders.Common
AC flexible sensors (large conductors / busbars / tight spaces)
CT7044:6000 A AC,loop diameter φ100 mm.
CT7045:6000 A AC,loop diameter φ180 mm.Common
CT7046:6000 A AC,loop diameter φ254 mm.
AC/DC auto-zero sensors
CT7731:100 A AC/DC, φ33 mm.
CT7736:600 A AC/DC, φ33 mm.
CT7742:2000 A AC/DC, φ55 mm.
Leakage current
CT7116:6 A AC, φ40 mm,for insulated conductors only.
Existing legacy sensors
L9910 conversion cable: Compatible with 9694 / 9660 / 9661 / 9669, CT9667-01/-02/-03, and 9657-10 / 9675. Note: the conversion cable does not supply power to the sensor.
4. Voltage Connection and Installation Accessories
PW9000:3P3W3M wiring simplification.
PW9001:3P4W wiring simplification.
9804-01 / 9804-02:red/black magnetic adapters that replace the L1000 alligator clip tips.
L9243:grabber clips for small or hard-to-clamp terminals.
L1021-01 / L1021-02:red/black branch cords for voltage tap connections.
Z5004 / Z5020: magnetic straps for securing the instrument to a distribution cabinet.
5. Data, Communication, Time Synchronization, and Carrying Options
Z4001 2 GB / Z4003 8 GB:for long-term recording; use genuine Hioki SD cards.
9642 LAN cable:for HTTP remote viewing, configuration, data transfer, and email notification environments.
9637 RS-232C cable:for serial communication.
PW9005 GPS Box:synchronizes the clock to UTC; ideal for multi-instrument measurements or dispute investigations.
C1009: soft carrying case with accessory compartments; C1002: hard carrying case. For long-term outdoor installation, an IP65 enclosure may be selected.
L0220-01 / -02 / -03: current sensor extension cables, 2 m / 5 m / 10 m.
