Tehonlaatu

Tehonlaatu, often translated as power quality, refers to the characteristics of electrical voltage and current supplied to a load. Good power quality ensures that electrical equipment operates reliably and efficiently without malfunctions or damage. It encompasses several aspects, including the waveform, frequency, and voltage level of the electricity. Deviations from the ideal sinusoidal waveform, such as harmonics, sags, surges, and flickers, can negatively impact connected devices. These disturbances can be caused by various factors, including the operation of non-linear loads like variable speed drives and power electronics, lightning strikes, switching operations in the power grid, and faults. Poor power quality can lead to increased energy consumption, reduced equipment lifespan, data errors, and production downtime. Monitoring and improving power quality are crucial for industries, data centers, and even residential consumers to ensure stable and dependable power. Solutions for power quality issues can include filters, voltage regulators, uninterruptible power supplies (UPS), and proper system design.
