Answer
An electrical fault refers to any issue that hinders an electrical system's proper operation or safety. Common types include:
- Short Circuit: Occurs when there's a low-resistance connection between live conductors, leading to excessive current flow. This can result from damaged wiring, such as nails piercing cables.
- Earth Fault: Happens when a live conductor contacts the earth or grounding system, potentially causing circuit breakers to trip. Common causes include insulation failure or moisture ingress.
- Broken Conductor: Involves a break in the wiring, disrupting the electrical flow and possibly leading to arcing or overheating.
- Insulation Resistance Fault: Occurs when insulation degrades, allowing unintended current paths, which can cause equipment malfunction or fire hazards. Factors like aging, heat, or chemical exposure contribute to this fault.
- High Resistance Fault: Involves unintended resistance in the circuit, leading to voltage drops and inefficient operation. This can result from loose connections or corrosion.
