Fluke 1777 - Power Quality Analyzer
Automatic measurements. More flexibility. Better power quality troubleshooting.
Fluke 1770 Series Three-Phase Power Quality Analyzers eliminate the complexities of power quality logging, troubleshooting, and analysis. Engineered to be the faster, easier way to perform power quality studies, the 1770 Series offers automatic measurements, a straightforward user interface and setup, best-in-class specifica- tions, and a simplified reporting platform. The instrument can also be powered directly from the measurement circuit, eliminating the need to find a power outlet or use a lengthy extension cord.
With the 1770 Series you’ll never miss a critical power quality event—from fast transients up to 8 kV, harmonics up to 30 kHz, dips and swells, as well as the voltage, current, and power measure- ments that enable you to characterize your electrical system.
Automatic measurement capture
Whether you’re performing a quick system check or a detailed power quality study, consistent data is key. The Fluke 1770 Series offers a unique automatic measurement capture system that helps ensure you’re collecting the right data every time, while still giving you the flexibility to select and adjust specific parameters as needed. More than 500 power quality parameters are cap- tured by default and the guided setup makes it easy to select the right parameters for the system you’re working on. Logged data
is instantly viewable, downloadable, and shareable with Fluke Energy Analyze Plus software so you never need to wait to finish a session before reviewing results or analyzing data.
Ultimate measurement confidence
The Fluke 1770 Series are 2-in-1 devices that combine the trouble- shooting functionality of a power quality meter with the robust analysis and logging capabilities of a standalone power quality analyzer—in a single, easy-to-use, handheld device.
The ‘PQ Meter’ function gives you immediate access to live on- screen data in the field so you can quickly identify potential problems while troubleshooting. The detailed ‘PQ Logging and Analysis’ function eliminates the complexity of performing power quality studies by guiding you through the setup process ensuring you’re capturing the right data every time. Couple these measure- ment modes with a unique measurement connection autocorrect function and you can be confident that you never need to worry about going back for a second measurement—even if you were unsure about what to look for when you started.

High-speed voltage transient capture

View real-time voltage transitory events while logging for faster troubleshooting
Transients negatively impact otherwise healthy systems every day and their potential to damage your equipment can’t be underestimated. Whether your system is experiencing impulsive or oscillatory transients, the results can be devastating and cause problems ranging from insulation failures to total equipment failures. The Fluke 1775 and Fluke 1777 incorporate advanced transient capture technology to help you clearly identify high-speed voltage transients, so you have the data you need to stop them in their tracks. The Fluke 1775 Power Quality Analyzer has 1MHz sampling capability to capture fast transients, while the Fluke 1777 Power Quality Analyzer has 20MHz sampling capability to capture the fastest transients in high detail.
From traditional industrial systems to renewable energy systems to electric vehicles, we’ve got you covered

A full range of harmonics are available from the first 50 integer harmonics and from 2 kHz to 30 kHz
The Fluke 1770 Series was designed to be safe and easy to use in any measurement environ- ment. The 1770 Series allows you to capture a full range of power quality variables as well as high-speed waveforms, high-speed transients, and higher frequency harmonics, all of which are instantly viewable on the large, high-resolution screen. With a best-in-class CAT IV 600 V / CAT III 1000 V overvoltage rating, these analyzers can be used at the service entrance or downstream, measuring AC and DC inputs, and harmonics measuring up to 30 kHz. With the 1770 Series you can be confident that you’ll capture the data you need to make better maintenance decisions no matter the task.

Work where, when, and how you want

Easily navigate using the large color touchscreen
No two days in the field are the same. You need a power quality analyzer that can go where you go and do what you need it to when you get there. With a full range of accessories and built-in features the Fluke 1770 Series makes it easier to get your job done. The slim ergonomic design and integrated hand strap make it easy to hold and the included hanging kit makes it easy to secure your analyzer inside a cabinet. The integrated internal power supply allows the unit to be powered directly from the measured circuit, while a 90-minute battery helps ensure you can still access and review data even when you aren’t connected to a live system. Quickly and easily transfer data to your PC using the USB C, USB A, Ethernet, WiFi, cellular network support options, depending on your requirements. With an internal GPS module and an optional double insulated external antenna, you can time sync your data for more accurate troubleshooting and analysis.
Calculate current harmonics limits
When downloading data from the Fluke 1770 Series Power Quality Analyzers the included Energy Analyze Plus software package can compare measured voltage and current harmonic statistical data to different standards, like EN 50160 or IEEE 519, to determine if they exceed compliance limits. This powerful predictive maintenance feature enables current harmonics to be observed before distortion appears in the voltage allowing you to prevent unexpected failures or non-compliance situations and increase system uptime. With the proliferation of inverter-based loads and power generation, keep- ing current harmonics in check is becoming increasingly critical to ensure reliable power quality and avoid system downtime.

Individual harmonics can be easily selected to view trend data as loads change
