Product Overview

The Fluke 1760 Three-Phase Power Quality Recorder is fully compliant to IEC 61000-4-30 Class-A, for advanced power quality analysis and consistent compliance testing. Designed for analysis of utility and industrial power distribution systems, in medium- and low-voltage networks, this power quality monitor provides the flexibility to customize thresholds, algorithms, and measurement selections. The 1760 power recorder captures the most comprehensive details on user-selected parameters.

Applications of the Fluke 1760 Power Quality Recorder include:

Detailed disturbance analysis – Perform high-speed transient analysis and uncover root cause of equipment malfunction for later mitigation and predictive maintenance. The fast transient option, with its 6000 V measurement range, allows capture of very short impulses such as lightning strikes.

Class-A quality-of-service compliance – Validate incoming power quality at the service entrance. Thanks to Class A compliance, the Fluke 1760 allows undisputable verification.

Event correlation at multiple locations – Utilizing GPS time synchronization, users can quickly detect where a fault occurred first, either inside or outside the facility.

Event correlation at multiple locations – Utilizing GPS time synchronization, users can quickly detect where a fault occurred first, either inside or outside the facility.

Galvanic separation and DC coupling – Allows complete measurements on dissimilar power systems. For example troubleshoot UPS systems by simultaneously recording the battery voltage and power output.

Power quality and power load studies – Assess baseline power quality to validate compatibility with critical systems before installation and verify electrical system capacity before adding loads.

Features of the Fluke 1760 3-Phase Power Quality Recorder include:

  • Fully Class-A compliant: Conduct tests according to the stringent international IEC 61000-4-30 Class-A standard
  • GPS time synchronization: Correlate data with events or datasets from other instruments with precision
  • Flexible and fully configurable thresholds and scale factors: Allows user to pinpoint specific issues by defining the detailed criteria for detection and recording of disturbances.
  • Uninterrupted power supply (40 minutes): Never miss important events - even record the beginning and end of interruptions and outages to help determine the cause

    • Fast Transients: Sample rate is selectable from 100 kHz to 10 MHz for channel 1-4 FFT of Fast Transients
  • Mains Signalling: Phases and N-conductor, Voltage and current
  • Online Mode: Variable refresh rate. This feature allows verification of instrument set up and delivers a quick overview of oscilloscope, transients and events.
  • 2 GB Flash Drive
  • Interfaces: Ethernet (100MB/s), compatible to Windows® 98/ME/NT/2000/XP RS 232, external modem via RS 232
  • Signalling Conditioning:

    • Overload capacity (rms): 1000 V, continuously
    • Voltage rise rate: max. 15 kV / µs
    • Input resistance: 1 MO
    • Input capacitance: 5 pF
    • 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.
