Features & Applications:
The Fluke 435 Three-Phase Power Quality Analyzer without Probe helps you locate, predict, prevent and troubleshoot problems in power distribution systems. This easy-to-use power quality tool is a “must have” for any person who maintains or troubleshoots three-phase power. The new IEC Class A standards for flicker and power quality are built right in to take the guess work out of power monitoring.
Features:
- Troubleshoot real-time: Analyze the trends using the cursors and zoom tools-even while background recording continues
- Highest safety rating in the industry: 600 V Cat IV/1000 V CAT III rated for use at the service entrance
- Automatic transient mode: Captures 200 kHz waveform data on all phases simultaneously: Up to 6 kV
- Fully Class A compliant: Conduct tests according to the stringent international IEC 61000-4-30 Class A standard
- Measure all three phases and neutral: With included four current probes
- AutoTrend: Every measurement you see is always automatically recorded, without any setup
- System-monitor: Up to seven power quality parameters on one screen according to EN50160 power quality standard
- Inrush mode: For troubleshooting nuisance circuit breaker tripping
- View graphs and generate reports: With included analysis software
- Logger function: Configure for any test condition with memory for over 400 parameters at user defined intervals
- Mains signaling: Measure interference from ripple control signals at specific frequencies
- Battery Life: Seven hours operating time per charge on NiMH battery pack
- Warranty: Rugged, handheld troubleshooter with Fluke three-year warranty
Applications:
- Frontline troubleshooting – quickly diagnose problems on-screen to get your operation back online
- Predictive maintenance – detect and prevent power quality issues before they cause downtime
- Quality of service compliance – validate incoming power quality at the service entrance
- Long-term analysis – uncover hard-to-find or intermittent issues
- Load studies – verify electrical system capacity before adding loads
- Energy assessments – quantify energy consumption before and after improvements to justify energy saving devices
