FLUKE 345

Fluke 345 Power Quality Clamp Meter Technical Data The ideal meter for commissioning and troubleshooting modern elecrtical loads With a bright color display to analyze the harmonic spectrum, a lowp- ass lter 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: Clampo- n measurement of ac current up to 1400 A rms and dc current up to 2000 A without breaking the circuit Highest safety rating:6 00 V CAT IV rated for use at the service entrance Accurate in noisy environment s:Even with distorted waveforms present on electronic loads with lowp- ass lter 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:E asily con rm instrument setup with large backlit color display of waveforms and trends 3-Phase power: Built in capability for balanced loads View graphs and generate report sW: ith included Power Log software N10140Applications Set up and troubleshoot variable frequency drives and UPS system s - Verify correct operation by measuring key parameters Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment Inrush capture - Check startu- p current where spurious resets or nuisance circuit breaker tripping occurs Load studies - Verify electrical system capacit y before adding loads Image Placeholder (application photo related to VFDs) Log measured parameters All voltage, current, power, and harmonic measurements can be logged for minutes, hours, or months. Measurement averaging periods from 1 second to 15 minutes can be selected depending on the application . Measured parameters can be logged into three separate recording memory areas. If longer recordings are required, the three areas may be combined into one. Stored measurements can be recalled and displayed ons- creen in normal screen Log parameters over time to track format or downloaded using the Power Log software package. down intermittent faults. Harmonics measurementsview key harmonic factors such as distortion factor and total harmonic distortion, as well th as individual harmonics up to the 3 0 harmonic. 2 Fluke Corporation Fluke 345 Power Quality Clamp Meter
