The Fluke 1773 Three-Phase Power Quality Analyser is a two-in-one power quality analyser and power quality meter capable of logging data, analysing measurements, and troubleshooting issues. The entry model in Fluke’s 1770 Series of PQAs, the Fluke 1773 Three-Phase Power Quality Analyser, is ideal for energy surveys and load testing, as well as harmonic surveys.
Optimised for simplicity and efficiency, the Fluke 1773 Three-Phase Power Quality Analyser features an easy-to-use interface, a simplified reporting platform, and automatic measurement capture. The streamlined user interface makes it easy to navigate between measurement parameters. As default, the Fluke 1773 Three-Phase Power Quality Analyser captures over five hundred power quality parameters. Its automatic measurement system ensures you collect the right data while allowing you to select and adjust parameters as required.
Harmonics, dips, swells, unbalance, voltage, current, and power, are amongst the five-hundred parameters measured by the Fluke 1773 Three-Phase Power Quality Analyser. Its PQ Meter function provides immediate access to live data, allowing you to identify potential problems quickly while troubleshooting. Data is visible via the Fluke 1773 Three-Phase Power Quality Analysers’ large, bright, touchscreen display.
Additionally, a PQ Logging and Analysis function delivers guided setups making it easy for you to configure the Fluke 1773 Three-Phase Power Quality Analyser. Moreover, guided setups help with selecting the required parameters for the system you are working on and will autocorrect measurement connections digitally meaning you don’t have to change the physical probe connections. Furthermore, the Fluke 1773 Three-Phase Power Quality Analyser supports the creation of custom views allowing you to tailor the PQA to carry out the tests and collect the data relevant to your application.
Data can be transferred to a PC via a USB or OPTIONAL Wi-Fi interface without interrupting the power quality or energy study. Once transferred, the supplied Fluke Energy Analyse Plus Software can be used to view and share results as well as create customised reports. Alternatively, the software’s one-click reporting function can be used to create industry-standard reports (e.g. EN 50160, IEEE 519, and GOST 33073).
Easy-to-use, efficient, and equipped with an eclectic selection of measurement capabilities, the Fluke 1773 Three-Phase Power Quality Analyser is also ergonomic. It can be powered directly from the measurement circuit, removing limitations that come from needing a power outlet or a lengthy extension cord.

Statistical Evaluation
Power quality statistics according to EN50160 and DISDIP tables like ITIC, CEBEMA, ANSI
Event List
Dips, swells and interruptions are detected and stored in the event list. Also any trigger which fires generates an event added to this list.
The Event list shows the exact time when the event occurred as well as the duration and magnitude. Sorting by several attributes of these events is possible to select one for further root cause analysis.
RMS values, transients and fast transients can be stored if a trigger fires.
Continuous Recording
Fluke 1760 records rms values together with corresponding minimum and maximum values for:
• Voltage
• Current
• Power P, Q, S
• Power Factor
• kWh
• Flicker
• Unbalance

Input filter
Each channel is equipped with a passive low-pass filter, an anti-aliasing filter and a 16-bit A/D converter. All channels are sampled synchronously with a common quartz-controlled clock pulse.
The filters protect against voltage transients and limit the signal rise rate, reduce high frequency components and especially the noise voltage above half the sampling rate of the A/D converter by 80 dB, thus achieving very small measuring errors in an exceptionally large amplitude range. This is also valid under extreme operating conditions like transient voltages at the output of converters.

Our checkout system automatically displays the available delivery services for your postcode and order weight, ensuring you always see the most suitable options.
Note: Heavy, bulky, or freight-only orders will be charged separately.
Our website is designed for quick, transactional purchases rather than bulk or palletised orders.
Please contact us in advance for a tailored freight quotation if your order falls into this category.
⏱ Dispatch & Delivery Timing
We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.
UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.
Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.
Once dispatched, your chosen delivery service determines how quickly your parcel arrives:
Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.
If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.
Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.
📅 Busy Periods & Delays
We always aim to dispatch promptly, but delivery times may be affected by:
Seasonal demand (e.g. Christmas, bank holidays, or industry shutdowns)
Courier network delays outside our control
Supplier lead times or calibration requirements for certain equipment
If your delivery is time-critical, please contact us before ordering so we can confirm stock and courier availability.
