Class A power quality analysers
Power Quality Analysis
Power quality is a broad term that traditionally encompasses voltage, frequency and waveform of a power supply system and how well or poor they conform to established specifications. Poor power quality translates to inefficient and even dangerous operation of supplied electrical systems and may lead to damage to connected equipment and risk of fire or electrocution and loss of production.
Metrel offers class A power quality analysers that are suitable for advanced troubleshooting of even the most complex electrical systems. Detect, record and analyse voltage dips, swells, sags, harmonic and interharmonic components and transients and other power quality events with ease.
