When a facility needs to investigate voltage disturbances, harmonic distortion, motor-starting events or unexplained equipment trips, a Class A power quality analyzer helps engineers collect consistent, defensible measurement data. The Fluke 1773 is a well-established choice. For customers exploring an AEMC alternative, the AEMC PowerPad® IV Model 8345 deserves a close look.
At a glance: The AEMC 8345 is a strong alternative to the Fluke 1773 for core Class A power quality measurements. It offers higher-order harmonic analysis (with current firmware), dedicated fast-surge capture and extensive network access. However, the Fluke 1773 specifically documents 2–30 kHz supraharmonic measurements; do not assume that the AEMC provides an identical capability.
Fluke 1773 vs AEMC 8345: Technical comparison
| Feature | Fluke 1773 | AEMC PowerPad IV 8345 |
|---|---|---|
| Power quality standard | IEC 61000-4-30 Class A, within specified nominal-voltage conditions | IEC 61000-4-30 Edition 3, Class A (Full) |
| Measurement connections | 4 voltage measurement inputs (3 phases + neutral referenced to PE); 4 current inputs | 5 isolated voltage inputs; 4 isolated current inputs |
| Maximum direct voltage | 1000 V rms AC / 1000 V DC | 1000 V AC/DC (specified measurement range starts at 5 V) |
| Electrical safety category | CAT III 1000 V / CAT IV 600 V | CAT IV 1000 V |
| Harmonic order | Up to 50th harmonic | Up to 127th harmonic with firmware v1.12 or later |
| Interharmonic order | Up to 50th interharmonic | Up to 126th interharmonic with firmware v1.12 or later |
| Supraharmonics | Documented 2–30 kHz analysis with defined frequency bins | Equivalent 2–30 kHz bin-based analysis is not explicitly confirmed in AEMC's published specifications |
| Published main sampling rates | 80 kS/s (voltage and current) | 400 kS/s voltage; 200 kS/s current |
| Fast transient / surge capture | No high-speed transient waveform capture on the 1773; available on Fluke 1775/1777 | Dedicated shockwave/surge mode: 2 MS/s, up to 12 kV transient peaks under specified conditions |
| Common PQ events | Dips, swells, interruptions, harmonics, inrush and related PQ events | Dips, swells, interruptions, harmonics, flicker, inrush and related PQ events |
| Connectivity | Ethernet and USB; wireless connectivity depends on accessory/configuration | Ethernet, USB, Wi-Fi, web-server access and remote control |
| Data analysis software | Fluke Energy Analyze Plus | AEMC DataView®; EN 50160 monitoring/reporting configuration |
| Onboard storage | 8 GB internal (expandable via microSD) | 16 GB SD card supplied |
Technical note: Sampling rates describe different acquisition paths and should not be treated as a stand-alone accuracy ranking. The AEMC's 12 kV figure is a transient surge-event specification, not a continuous voltage input or safety-category rating. Features may depend on firmware, accessories, wiring topology and setup.
Where does the AEMC 8345 stand out?
1. Extended harmonic analysis
With the applicable firmware, the 8345 measures harmonic orders through the 127th and interharmonics through the 126th. This can be useful when investigating complex industrial electrical environments, subject to the instrument's specified measurement bandwidth and analysis methods.
2. Dedicated surge-event capture
Its shockwave mode samples at up to 2 MS/s and is specified for transient peaks up to 12 kV. That gives investigators a high-speed event-capture function not included in the Fluke 1773 base model.
3. Flexible remote access
USB, Ethernet, Wi-Fi and web-server functionality support local and remote workflows. AEMC also documents alarm email notifications, useful for supervised power quality monitoring.
4. Higher CAT IV voltage rating
The 8345 carries a CAT IV 1000 V rating, compared with CAT IV 600 V / CAT III 1000 V on the Fluke 1773. Always use compatible leads and probes and follow the lowest applicable rating in the measurement setup.
Where does the Fluke 1773 still make sense?
The Fluke 1773 remains a capable Class A analyzer for everyday power quality surveys. Its guided measurement setup and Energy Analyze Plus software may suit teams already trained on the Fluke ecosystem. Importantly, Fluke publishes supraharmonic analysis from 2 to 30 kHz, which may matter for applications involving switching equipment and high-frequency emissions.
Which analyzer is better for your application?
Industrial maintenance and plant troubleshooting
Consider the AEMC 8345 for three-phase voltage quality studies, harmonics, flicker, inrush and investigation of intermittent disturbances, especially when remote access or dedicated fast-event capture is useful.
Utility and engineering power quality reporting
Both models deserve consideration when IEC 61000-4-30 Class A data is required. Confirm the required monitoring standard, report format, sensor range, installation category and nominal voltage before purchase.
Projects specifying 2–30 kHz supraharmonics
Check the Fluke 1773 requirement closely. Its published specifications cover this band. AEMC 8345's published harmonic-order range alone does not establish direct equivalence for this measurement.
Recommended AEMC 8345 configurations at RCC Electronics
The appropriate kit depends on conductor size, expected current, required accessories and whether compatible current sensors are already available.
RCCE product listings and manufacturer kit specifications may change. Verify the exact sensor model, current range, lead set, availability and delivery schedule before ordering.
Frequently asked questions
Is the AEMC 8345 a direct replacement for the Fluke 1773?
For many core Class A three-phase power quality surveys, the AEMC 8345 is a strong alternative. It is not a guaranteed one-for-one replacement for every specialized function, including documented supraharmonic measurement workflows.
Does the 8345 require software to analyze recorded data?
AEMC supplies DataView® software for downloading, analyzing and reporting recorded measurements. Some compliance-report workflows, including EN 50160 configurations, use this software.
Which current probes should I order?
Choose based on the expected current range, conductor diameter, required accuracy and measurement conditions. RCC Electronics can help select the appropriate bundled or optional sensors.
