jännevaurioita
Jännevaurioita refers to damage or failure in electrical conductors, typically wires or cables, due to excessive current flow. This phenomenon is often caused by overloading, short circuits, or electrical arcing. When a conductor is subjected to a current greater than its rated capacity, it can experience thermal stress, leading to insulation degradation and eventual failure. This can result in a variety of issues, including fires, equipment damage, and power outages.
The primary causes of jännevaurioita include:
1. Overloading: When too many electrical devices are connected to a single circuit, the current exceeds the
2. Short circuits: A short circuit occurs when the insulation between conductors breaks down, allowing current
3. Electrical arcing: Arcing happens when an electrical current jumps across a gap, creating a plasma channel
Preventing jännevaurioita involves proper circuit design, using conductors with appropriate current ratings, and implementing protective devices
