Fluke 1745 Power Quality Logger
Disturbance Analyzers – Fluke 1745 three-phase power quality logger is capable of logging up to 500 power parameters for up to 85 days.
Overview
Power quality logging is easy with a compact and rugged Fluke power meter
The Fluke 1745 Three-phase Power Quality Logger is an everyday power meter for technicians who troubleshoot and analyze power quality issues. Capable of simultaneously logging up to 500 power parameters for up to 85 days and monitoring for events, these power loggers help uncover intermittent and hard-to-find power quality issues. The included PQ Log software quickly assesses the quality of power at the service entrance, substation, or at the load, according to the latest EN50160 standard.
Applications
- Disturbance analysis – Uncover root cause of equipment malfunction for later mitigation and predictive maintenance
- Quality of service compliance – Validate incoming power quality at the service entrance
- Power quality studies – Assess baseline power quality to validate compatibility with critical systems before installation
- Load studies – Verify electrical system capacity before adding loads
- Energy and power quality assessment – Validate performance of facility improvements by quantifying energy consumption, power factor, and general power quality before and after improvements
Features
- Plug and play: Setup in minutes with automatic current probe detection and powering
- Installs inside the cabinet: Compact, fully-insulated housing and accessories fit easily in tight spaces next to live power
- Determines the root cause: Included PQ Log software quickly analyzes trends, creates statistical summaries, and generates detailed graphs and tables
- Monitors power for the long-term: Data can be downloaded during recording without interruption
- Measure voltage with premium accuracy: IEC61000-4-30 Class-A compliant voltage accuracy (0.1%)
- Quickly validate quality of power: Assess power quality according to EN50160 power quality standard with statistical overview
- Rugged and reliable: Designed for everyday field use with no moving parts and durable insulated case with two year warranty
