Fluke 1777 Power Quality Analyser
The Fluke 1777 Three-Phase Power Quality Analyser eliminates the complexities of power quality logging, troubleshooting, and analysis. Engineered to be the faster, easier way to perform power quality studies, the Fluke 1777 offers automatic measurements, a straightforward user interface and 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 Fluke 1777 you’ll never miss a critical power quality event—from fast transients up to 8 kV, dips and swells, as well as the voltage, current, and power measurements that enable you to characterize your electrical system.
The Fluke 1777 is a 2-in-1 device that combines the troubleshooting functionality of a power quality meter with the robust analysis and logging of more than 500 power quality parameters in a single, easy-to-use, handheld device. The Fluke 1777 was designed to be safe and easy to use in any measurement environment.
The Fluke 1777 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 analysers can be used at the service entrance or downstream, measuring AC and DC inputs, and harmonics measuring up to 30 kHz.
With the Fluke 1777 you can be confident that you'll capture the data you need to make better maintenance decisions no matter the task. The 'PQ Meter' function gives you immediate access to live onscreen 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 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 measurement.
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 1777 incorporates 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 1777 Power Quality Analyser has 1MHZ and 20MHz sampling capability to capture the fastest transients in high detail.
The Fluke 1777 offers the best-in-class accuracy you've come to expect from a Fluke Power Quality Analyser in a IEC 61000-4-30 Class A edition 3 compliant package. On top of that, the 1777 Series has been engineered to meet the future requirements of Class A edition 4, for conformance to EN 50160 and IEEE 519.
Ideal for: Energy surveys and load testing, Harmonic surveys, Nuisance circuit breaker tripping, Power utility power quality surveys, Discovery of equipment failures caused by transients.
