Jännitepiikeiltä

Jännitepiikeiltä, often translated as voltage spikes or transients, are sudden, short-duration increases in electrical voltage that can occur in power systems. These events are typically much higher than the normal operating voltage and can be caused by a variety of factors. Common sources include lightning strikes, the switching of large electrical loads like motors or industrial equipment, and faults within the power grid.

These transient overvoltages can travel through electrical wiring and reach sensitive electronic devices. The impact of jännitepiikeiltä can range from minor disruptions, such as temporary data loss in computers, to significant damage, including the complete failure of electronic components. In industrial settings, such spikes can lead to costly downtime and repair expenses.

Protection against jännitepiikeiltä is achieved through various surge protection devices (SPDs). These devices are designed to detect overvoltage conditions and divert the excess energy away from connected equipment, typically to ground. Surge protectors are commonly found in residential settings, protecting electronics like televisions and computers, as well as in industrial and commercial power distribution systems to safeguard critical machinery and infrastructure. Proper grounding and surge suppression are essential for maintaining the reliability and longevity of electrical and electronic systems.
