Fluke 1760 Three-Phase Power Quality Recorder (Class-A)

Overview

The Fluke 1760 is a premium power quality recorder designed for medium- and low-voltage networks in industrial, utility, and facility environments. It is fully compliant with IEC 61000-4-30 Class A requirements, enabling legally defensible measurements of power quality. The recorder features 8 galvanically isolated input channels, plug-and-play sensor detection, built-in 40-minute uninterrupted power capability, and GPS time synchronization to correlate events across multiple units. With a 2 GB flash memory and advanced triggering options, the 1760 can capture detailed waveforms, RMS statistics, transients, events, harmonics, flicker, power, and signaling voltages simultaneously.

It is widely applied in power quality audits, root-cause analysis of disturbances, certification to standards (e.g. EN 50160), load studies, validation of new installations, UPS and DC-bus monitoring, and correlation of multi-site events.

Key Features

• Class-A compliance per IEC 61000-4-30 for accurate, repeatable, and comparable PQ measurements

• 8 isolated input channels (voltage + current) with galvanic separation

• 10 MHz transient waveform capture, up to 6,000 V peak, to catch very short disturbances

• GPS time synchronization for timestamp correlation among multiple units

• Uninterrupted power (UPS) backup up to 40 minutes to capture interruptions and recovery events

• 2 GB internal flash memory for long-term data storage

• Plug-and-play automatic sensor detection, instrument powers sensors

• Comprehensive PQ parameter measurement: RMS, events (dips, swells, interruptions), harmonics up to 50th, interharmonics, flicker, imbalance, frequency, power (P, Q, S), power factor, signaling voltages

• Dual coupling modes / DC coupling allowing measurement of DC or mixed systems

• Interfaces: Ethernet (100 Mb/s), USB, RS-232, data retrieval without stopping logging

• Rugged field design, no rotating parts, insulated housing, wide operating environment

• Flexible trigger and threshold configuration for user-defined detection criteria

Applications

• Power quality auditing and compliance verification

• Disturbance root cause analysis (e.g. capacitor switching, lightning, harmonics)

• Load profiling and energy / power studies before system upgrades

• Monitoring of UPS, DC-bus, hybrid systems with mixed AC/DC signals

• Multi-location event correlation using synchronized timestamps

• Commissioning of new installations and verification of compliance to standards

• Long-term PQ trending in industrial plants, data centers, hospitals, utilities
