⚡ Introduction: The Hidden Danger of PEN Faults
PEN faults are often invisible but can be incredibly dangerous. Understanding how they occur and how to protect yourself is crucial for every EV owner.
🔧 What Causes a PEN Fault?
PEN faults typically arise from:
-
Damaged or Broken PEN Conductors: Physical damage to the combined protective earth and neutral conductor.
-
Loose Connections: Poor connections in the electrical system can lead to faults.
-
Corrosion: Over time, corrosion can weaken the PEN conductor, leading to faults.
🧪 How to Detect a PEN Fault
Detecting a PEN fault requires specialized equipment. A PEN fault detection device continuously monitors the integrity of the PEN conductor. If it detects an anomaly, it can trigger an alarm or disconnect the power supply to prevent hazards.

-
Install a PEN Fault Detection Device: These devices monitor the PEN conductor and disconnect the charger in case of a fault.
