Many engine malfunctions can be identified without disassembly - right on site. This saves time and allows you to assess the condition of operating equipment. Let's look at the methods of field diagnostics.
What can be checked without disassembly
- Insulation resistance - with a megger.
- Winding resistance - for breaks and distortion.
- Vibration - with a vibrometer.
- Heating - thermal imager.
- Currents by phase - current clamps.
What the methods show
| Method | Identifies |
|---|---|
| Insulation measurement | Breakdown, humidification |
| Vibration diagnostics | Imbalance, bearing wear, misalignment |
| Thermal imager | Local overheating, turn short circuit |
| Current analysis | Phase loss, broken rods rotor |
Advantages of field diagnostics
Diagnostics without disassembly is especially valuable for large engines, the dismantling of which is difficult and expensive. A specialist goes to the site and, based on a combination of measurements, gives a conclusion about the condition - without stopping for a long time.
However, some defects (for example, hidden damage to the winding) are revealed only during disassembly. If field diagnostics show a winding problem, an in-depth inspection and possibly rewinding will be required.
