🧪 Testing of Underground Cables
Before using or after repairing, cables must be tested to ensure safety and performance.
🔧 Common Tests:
| 🧪 Test Type | 📝 Purpose |
|---|---|
| Insulation Resistance Test | Checks if insulation is intact |
| Continuity Test | Verifies the conductor is not broken |
| High Voltage (HiPot) Test | Tests insulation under high voltage stress |
| Earth Fault Test | Detects leakage current to earth |
| Sheath Test | Checks if outer sheath is damaged |
🧰 Tools used:
Megger (for insulation test)
Multimeter (for continuity and fault detection)
High Voltage Tester
