Product Overview: Fluke 1770 Series Three-Phase Power Quality Analyzer
The Fluke 1770 Series Three-Phase Power Quality Analyzer empowers professionals to diagnose power issues quickly and accurately. Its automatic event capture and guided setup features eliminate guesswork, allowing you to focus on results rather than configuration. With a wide dynamic range and simultaneous sampling of all three phases, it provides precise insight into energy consumption, harmonics, voltage dips, and transient disturbances. Seamless data transfer and the included Fluke Energy Analyze Plus software make reporting fast and compliant with IEC 61000-4-30 Class A standards. Built to perform in tough environments, the Fluke 1770 Series combines advanced performance with ease of use—perfect for troubleshooting, commissioning, and long-term energy studies.
Get accurate, efficient power analysis with the Fluke 1770 Series—order today from JM Test Systems.
Quickly and easily transfer data to your PC using the USB C, USB A, Ethernet, Wi-Fi, cellular network support options, depending on your requirements. With an internal GPS module and an optional double insulated antenna extension cable, for amplifying GPS signals indoors, you can easily time sync your data for more accurate troubleshooting and analysis.
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, keeping current harmonics in check is becoming increasingly critical to ensure reliable power quality and avoid system downtime.
