Fast & Reliable
Make data capture as reliable and easy as possible with the power quality analyzer that features instrument powering from the measurement circuit, automatic connection check, and correction.
The 1775 Power Quality Analyzer replaces the discontinued 435-II Power Quality and Energy Analyzer
Features
Applications
Automatic measurements. More flexibility. Better power quality troubleshooting
The 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 s automatic measurements, a straightforward user interface and setup, best-in-class specifications, 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 youÂll never miss a critical power quality eventÂfrom fast transients up to 8 kV, harmonics up to 30 kHz, dips and swells, as well as the voltage, current, and power measurements that enable you to characterize your electrical system.
Automatic measurement capture
Whether youÂre performing a quick system check or a detailed power quality study, consistent data is key. The power quality analyzer s a unique automatic measurement capture system that helps ensure youÂre 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 captured by default and the guided setup makes it easy to select the right parameters for the system youÂre 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 three-phase power quality analyzers are 2-in-1 devices that combine the troubleshooting functionality of a power quality meter with the robust analysis and logging capabilities of a standalone power quality analyzerÂin a single, easy-to-use, handheld device.
The ÂPQ Meter function gives you immediate access to live onscreen data in the field so you can quickly identify potential problems while troubleshooting. The detailed ÂPQ Logging and Analysis function eliminates the complexity of performing power quality studies by guiding you through the setup process ensuring youÂre capturing the right data every time. Couple these measurement 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 measurementÂeven if you were unsure about what to look for when you started.
View real-time voltage transitory events while logging for faster troubleshooting High-speed voltage transient capture
Transients negatively impact otherwise healthy systems every day and their potential to damage your equipment canÂt 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 1775 and 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 1775 Power Quality Analyzer has 1MHz sampling capability to capture fast transients, while the 1777 Power Quality Analyzer has 20 MHz sampling capability to capture the fastest transients in high detail.
A full range of harmonics are available from the first 50 integer harmonics and from 2 kHz to 30 kHz From traditional industrial systems to renewable energy systems to electric vehicles, weÂve got you covered
The three-phase power quality analyzer was designed to be safe and easy to use in any measurement environment. The three-phase power quality analyzer 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 youÂll capture the data you need to make better maintenance decisions no matter the task.
Easily navigate using the large color touchscreen Work where, when, and how you want
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 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 arenÂt 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.
Individual harmonics can be easily selected to view trend data as loads change Calculate current harmonics limits
When downloading data from the 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.
