Fluke 1777 Three-Phase Power Quality Analyser

The Fluke 1777 power analyser and trouble-shooter is the most advanced tester in the Fluke 1770 series. This version of the Fluke 1777 includes four 24 inch iFlex current probes, suitable for measuring up to 1500A AC. The thin and flexible design of the iFlex probe makes it easy to take measurements where space is very limited.

Super simple setup

The Fluke 1777’s guided set up process and unique measurement connection autocorrect function significantly reduce the chance of user error. Once testing has begun, the Fluke 1777 will automatically capture 500 power quality parameters including voltage, current, power, dips, swells, harmonics and high speed transients up to 8kV.

The interface is logical and easy to use. Navigation can be made via the large touch screen or rubber buttons. Use of the Fluke 1777 is still possible whilst wearing PPE.

Analyse and troubleshoot in one

See measurements in real time as they happen. Ideal for troubleshooting issues out in the field. Alternatively, for intermittent faults, the Fluke 1777 can be set to log data over time. The 1777 even powers itself from the circuit under test, so there is no worrying about battery life. There is also a 90 minute battery life for reviewing measurements and downloading of results.

With its vast range of features and function, the Fluke 1777 is safe and easy to use in any environment Furthermore, the 1777 has CAT IV 600 V / CAT III 1000 V overvoltage rating, so it can be used all the way from the service entrance or further downstream, measuring AC and DC inputs, and harmonics measuring up to 30 kHz.

High-speed voltage transient capture

Impulsive and oscillatory transients can be damaging to otherwise healthy systems, causing problems ranging from insulation failures to total equipment failures. The Fluke 1777 can clearly capture transients up to 8kV with 1MS/s and 20MS/s sampling rates, making the Fluke 1777 a powerful preventive maintenance tool.

Always by your side

With a range of accessories included, such as the adjustable hand strap; combined with the 1777’s ergonomic design, it makes for comfortable use whilst out in the field. A hanging strap and stand means the tester stays put when longer term data logging is required. 

Fluke Energy Analyse Plus

This powerful software package is included with the Fluke 1777. Results can be downloaded, analysed, tracked and reported on whilst still in the field, or after a study has been completed.

Quickly compare results to historical values, benchmark against industry norms like EN 50160 or IEEE 519, compare measured data to local conditions, and create a more complete picture of what’s occurring across your facility.

Observe current harmonics 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.
