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
