What is power quality?
In an ideal three phase power system, voltages are at nominal magnitude and frequency, perfectly balanced and with a perfect sinusoidal waveform. Any disturbance on one parameter (magnitude, frequency, waveform, or symmetry) is classified as a power quality issue. There are a variety of power quality disturbances – voltage dips, harmonics, transients, etc. – all of which can have negative impacts on the electrical system and equipment, such as power outage, device damage, failure, overheating, degraded performance and reduced equipment life.

AccuSine PFV+ stops power quality issues like voltage sags and flicker due to load current fluctuations (VAR compensation). For larger power quality applications, AccuSine PFV+ can be combined with a capacitor bank to reduce system cost. It can add or subtract to the capacitor bank output, achieving high speed reactive compensation with infinite resolution. It also provides high speed Powoer Factor correction where traditional capacitor banks are unable to track loads.

• Fast ROI - displacement PF correction stops utility charges for poor PF (instant savings where penalty is charged).
• Maximizes uptime and production scheduling - mains current balancing prevents unwanted/unplanned stoppages.
• Easy expansion or retrofit - parallel connection means initial or additional unit installation with no load interruptions
• Simple and intuitive to use - touch-screen HMI with communication via RS485/RJ45 connector.
• Easy remote monitoring and operational control (via Ethernet TCP/IP).
• Flexible and scalable.
• Peace of mind - worry-free power factor correction without the risk of resonance.
