Tehonlaadun

Tehonlaadun is a Finnish term that translates to "power quality" in English. It refers to the measurement and assessment of the characteristics of electricity supplied by the power grid to a consumer's premises. Good power quality means that the voltage, frequency, and waveform of the electricity are stable and within acceptable parameters. Poor power quality can manifest in various ways, including voltage sags (dips), voltage swells, harmonics, and interruptions.

Factors that can affect power quality include faults within the electrical grid, the operation of large industrial equipment, lightning strikes, and issues with a building's internal wiring. Devices sensitive to power fluctuations, such as computers, medical equipment, and modern electronics, are particularly vulnerable to the negative impacts of poor power quality. These impacts can range from minor inconveniences like flickering lights to significant problems like data corruption, equipment malfunction, and premature wear of electrical components.

Maintaining good power quality is crucial for the reliable and efficient operation of electrical systems and equipment. Utilities often monitor power quality to identify and address problems within the grid. Consumers may also invest in power quality monitoring equipment or mitigation devices like uninterruptible power supplies (UPS) or surge protectors to safeguard their sensitive electronics. Understanding and managing tehonlaadun is therefore an important aspect of electrical system maintenance and operational efficiency.
