On-Site Measurements-Power Quality and Transients

ON-SITE MEASUREMENTS - POWER QUALITY AND TRANSIENTSUsing state-of-the-art equipment, power quality measurements can be performed in accordance with current standards (IEC 61000-4-30, EN 50160, IEEE std 519, etc.).

Key features:
– Voltage and current harmonics
– Interharmonics
– Flicker
– Voltage unbalance
– Rapid voltage changes
– Frequency
– Voltage Sags and Dips

Fast transient voltage and current measurements are performed with high-tech portable equipment (Rogowsky current transducers, voltage transducers based on electrical field sensing technology, high band pass instruments, high speed data acquisition, etc.).

Monitoring can be performed for long periods of time at remote plants, e.g.windmills.

Power quality and transient measurements often help to identify equipment misoperations and are used for root cause failure analysis.
