Fluke 1736 Three-Phase Power Quality Logger
Fluke 1736 Three-Phase Power Quality Logger is designed for load studies, energy assessments and detailed power quality investigation on three-phase systems. It can capture and log more than 500 power quality parameters, giving technicians a broad view of electrical performance from one instrument. Measurements include RMS voltage, RMS current, power, energy, power factor, harmonics, THD and voltage or current events.
Four flexible current probes allow measurement of all three phases and neutral, while the instrument identifies and scales each connected probe. The included iFlex probes can be set for either 150 A or 1500 A operation, helping users match the measurement range to the task. A 4.3-inch full-colour touch screen with an active matrix TFT display provides a clear interface for guided set-up, checks and field analysis.
For fault finding, the Fluke 1736 Three-Phase Power Quality Logger records dips, swells and inrush currents together with waveform snapshots, timestamps and event severity. More than 20 separate logging sessions can be stored on the instrument, while automatically logged values help reduce the risk of losing key measurement trends. Fluke Connect compatibility and Fluke Energy Analyse Plus software also support remote access, analysis and reporting of recorded results.
Key Benefits
- Measures all three phases and neutral using four flexible current probes.
- Logs more than 500 power quality parameters to support detailed system assessment.
- Stores more than 20 separate logging sessions directly on the instrument.
- Captures dips, swells and inrush currents with waveform snapshots, timestamps and event severity.
- Uses a full-colour touch screen for guided set-up, field checks and graphical analysis.
- Provides digital verification to help identify and correct common connection errors.
- Supports Fluke Connect for remote access and sharing of measurement information.
- Works with Fluke Energy Analyse Plus for analysis, charting and report creation.
- Records voltage and current harmonics up to the 50th harmonic to aid harmonic fault finding.
- Allows in-the-field set-up without needing a workshop or PC terminal.
Common Applications
Fluke 1736 Three-Phase Power Quality Logger is suitable for a range of testing, maintenance and inspection tasks, including:
- Load studies to verify electrical system capacity before additional loads are connected.
- Energy assessments before and after improvements to quantify energy consumption.
- Power quality surveys across three-phase electrical systems.
- Harmonic measurement to identify issues that may affect critical equipment.
- Voltage dip and swell monitoring.
- Inrush current event capture.
- Power factor and active or reactive power assessment.
- Investigation of false resets and nuisance circuit breaker tripping.
- Assessment of voltage and current distortion.
- Long-term logging for system reliability and energy studies.
Why Choose This Model?
The Fluke 1736 combines three-phase and neutral measurement, logging of more than 500 power quality parameters, event capture, a full-colour touch interface and Fluke Connect compatibility in one instrument. Its included four flexible probes and Energy Analyse Plus software make it suited to both field measurement and later analysis or reporting.
