Jännitespiikit

Jännitespiikit, also known as voltage spikes or transients, are sudden, brief, and significant increases in electrical voltage that occur above the normal operating level. These events are typically very short in duration, often lasting only microseconds. Jännitespiikit can be caused by a variety of factors, both internal and external to an electrical system.

Common internal causes include the switching of inductive loads, such as motors, transformers, or fluorescent lights, when they are turned on or off. The stored energy in these inductive components can be released rapidly as a voltage surge. Internal electrical system faults or short circuits can also generate jännitespiikit.

External sources are also significant contributors. Lightning strikes are a primary cause of severe jännitespiikit, as they can induce high voltages into power lines and connected equipment. The operation of heavy machinery or the connection and disconnection of large electrical loads by utility companies can also introduce transients into the power supply.

The effects of jännitespiikit on electronic equipment can range from minor glitches to catastrophic failure. Sensitive electronic components, particularly microprocessors and integrated circuits, are highly susceptible to damage from overvoltage. Even seemingly minor spikes can degrade components over time, leading to premature equipment failure. To mitigate the risks associated with jännitespiikit, surge protection devices (SPDs) are commonly employed. These devices divert excess voltage away from sensitive equipment, thereby protecting it from damage.
