FLUKE-1773/BASIC Three-Phase Power Quality Analyzer (No probes)

The 1773 Three-Phase Power Quality Analyzer (PQA) is a rugged, portable tool designed for fast, easy power quality troubleshooting. With automatic measurements, an intuitive interface, and streamlined setup, it simplifies power quality studies without compromising on performance. Its compact design and ability to draw power directly from the measurement line make it ideal for both live diagnostics and long-term logging.

As the entry-level model in the 1770 Series, the 1773 is built for users who need reliable power quality analysis without the advanced transient capture or built-in wireless connectivity found in the 1775 and 1777 models. While it doesn’t include WiFi or LTE, it supports USB, Ethernet, and WiFi Direct for flexible data transfer. Users can also add wireless capabilities through external modules, allowing the device to adapt to different environments and evolving needs.

Automatic Measurement Capture

The analyzer's system automatically records over 500 power quality parameters by default, ensuring you always gather the right data. You still have the flexibility to fine-tune and select specific parameters as needed. A guided setup simplifies configuration, and with Fluke Energy Analyze Plus software, you can instantly view, download, and share logged data—no need to wait until the session ends

Reliable Measurement Confidence

The built-in ‘PQ Meter’ function provides real-time data on-site, helping you quickly spot issues during troubleshooting. The ‘PQ Logging and Analysis’ feature walks you through setup, making complex power quality studies easier. Combined with an automatic connection correction feature, you can trust your measurements are accurate the first time—no need for repeat visits.

Harmonics Compliance Monitoring

When data is downloaded, the Energy Analyze Plus software can compare harmonic data against standards like EN 50160 or IEEE 519 to determine if they exceed compliance limits. This helps detect current harmonics before they distort voltage, allowing for proactive maintenance and improved system reliability—especially important with the rise of inverter-based systems.

Energy Loss in Real Money

The Energy Loss Calculator (ELC) mode identifies where energy is being wasted in your system using Fluke’s patented Unified Power calculation, translating inefficiencies into actual financial losses.

Wasted energy comes from:

• Transmission of effective power – Heat generated as power flows through cables

• Reactive power – Does not drive the load but consumes energy

• Unbalance losses – Unbalanced loads contribute to wasted energy

• Distortion power – Non-linear loads create harmonics that consume power, but do not perform work

• Neutral losses – Neutral losses can be due to both unbalance and harmonics, leading to increased heat and requiring larger conductors

Powerful Analysis Software with Easy-to-Create Reports

Energy Analyze Plus helps you evaluate power quality data right out of the box and without extensive training. It makes downloading, analyzing, tracking, and reporting power quality and energy data easier than ever. Quickly compare results to historical values, benchmark against industry norms, compare measured data to local conditions, and create a more complete picture of what’s occurring across your facility—all while data is still being collected.
