Fluke 345 Power Quality Clamp Meter with USB Interface :
With a bright color display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise, and a high EMC immunity design, the Fluke 345 is ideal for measurements on switching loads such as variable frequency drives, electronic lighting and UPS systems. Additionally, the Hall Effect measurement system makes measurement of dc current possible without the need to break the circuit, and the internal memory enables long-term logging for analysis of trends or intermittent problems.
• AC/DC current: Clamp-on measurement of ac current up to 1400 A rms and dc current up to 2000 A without breaking the circuit • Highest safety rating: 600 V CAT IV rated for use at the service entrance • Accurate in noisy environments: Even with distorted waveforms present on electronic loads with low-pass filter • Data logging: Identify intermittent faults by logging any power parameters for minutes or months, including harmonics • Verify batteries: Direct measurement of dc ripple (%) for battery and dc systems • Troubleshoot harmonics: Analyze and log harmonics digitally or graphically • Inrush current: Capture and analyze nuisance tripping, from 3 seconds to 300 seconds • Easy to use: Easily confirm instrument setup with large backlit color display of waveforms and trends • 3-Phase power: Built in capability for balanced loads • View graphs and generate reports: With included Power Log software
Applications: **Set up and troubleshoot variable frequency drives and UPS systems - Verify correct operation by measuring key parameters ***Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment ***Inrush capture - Check start-up current where spurious resets or nuisance circuit breaker tripping occurs ***Load studies - Verify electrical system capacity before adding loads
