Tehokerroinparannus

Tehokerroinparannus, often translated as power factor correction, is a technique used in electrical power systems to improve the efficiency of power transmission. It involves adjusting the power factor of an electrical load to be closer to unity, which is the ideal value. The power factor is a measure of how effectively electrical power is being used. A low power factor indicates that a significant portion of the current is used to establish and maintain magnetic fields rather than for doing useful work.

This inefficiency leads to several problems, including increased current flow, higher losses in transmission lines, and reduced capacity of electrical equipment. Tehokerroinparannus aims to mitigate these issues. The most common method for achieving power factor correction is by installing capacitor banks, which supply reactive power to inductive loads. This reactive power compensates for the lagging reactive power drawn by inductive loads, thereby improving the overall power factor.

In industrial settings, where motors and other inductive equipment are prevalent, low power factors are common. Implementing tehokerroinparannus in these environments can lead to significant cost savings through reduced electricity bills, as utility companies often penalize customers for low power factors. Additionally, it can extend the lifespan of electrical equipment by reducing the stress caused by higher currents and heat generation. The process typically involves analyzing the load characteristics and selecting the appropriate capacitor bank size and configuration for optimal performance.
