Fluke 1770 series three-phase power quality analysers

The Fluke 1770 Series three-phase Power Quality Analyzers are designed as the faster and easier way to analyse mains power quality, offering automatic measurements, a simple 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 socket or use a long extension cord. Find out how to detect energy waste by managing grid power quality here.

With the Fluke 1770 series of three-phase Power Quality Analyzers, you'll never miss another critical power quality event - from fast transients up to 8 kV, harmonics up to 30 kHz, voltage fluctuations and the voltage,current and power measurements that allow you to characterise your electrical system.

Advantages:

- Automatically measures and records important power quality parameters (harmonics, voltage fluctuations, unbalance, inrush current, etc.).
- Bright, large touchscreen with physical navigation buttons and optimised user interface.
- Guided set-up procedure for fast and safe installation, including the ability to automatically digitally correct measurement connections without changing the physical probe connections.
- Ability to set custom views for quick access to the tests and data most important to you
- Flexibility in data transfer (e.g. PC to USB, Wi-Fi, mobile connection, USB direct), without interrupting your power quality or energy analysis.
- Renewed software package (Energy Analyze Plus) for modern, intuitive data analysis and reporting.

Powerful analysis software with easy report creation

Fluke 1770 series three-phase Power Quality Analyzers come standard with the powerful Fluke Energy Analyze Plus software, designed to eliminate the problems found with other multi-function application software. Energy Analyze Plus helps you evaluate power quality data. You do not need extensive training and can start using it immediately.

Energy Analyze Plus makes downloading, analysing, tracking and reporting grid quality and energy data easier than ever. Quickly compare results to historical values, compare them to industry standards, compare measured data to local conditions and create a more complete picture of what's happening in your facility, even as the data is still being collected. Energy Analyze Plus provides integrated support for the Fluke 1730-, 1740- and 1770-series energy loggers and Power Quality Analyzers.
