Fluke 1773/1775/1777 3 Phase Power Quality Analyzer
Fluke three-phase power quality analyzers (represented by the 1770 Series) are advanced, portable test instruments designed to measure, record, and analyze power quality parameters in three-phase electrical distribution systems. Compliant with IEC 61000-4-30 Class A standards, they enable accurate troubleshooting, compliance verification, and energy loss assessment for low- and medium-voltage networks. The 1770 Series (e.g., FLUKE-1773, 1775, 1777) features automatic measurements, a user-friendly touchscreen interface, and rugged construction for reliable field use.
Key Applications
- Power Quality Troubleshooting: Identify voltage dips/swells, harmonics, transients, unbalance, and frequency deviations causing equipment malfunction.
- Energy Management & Loss Calculation: Measure power consumption, calculate energy losses, and optimize efficiency to reduce operational costs.
- Compliance Testing: Verify compliance with international standards (e.g., EN 50160, IEC 61000-4-30) for utility and industrial power systems.
- Preventive Maintenance: Monitor critical equipment (motors, drives, transformers) to predict failures and schedule maintenance.
- Load Studies & Commissioning: Assess system capacity before adding loads and benchmark power quality during equipment installation.
