Fluke 345

Power Quality Clamp Meter

The ideal meter for commissioning and troubleshooting modern electrical loads

         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
