S/N | Identified Risk Item | Consequences | Possible Causes | Mitigation plan |
1 | Insulation breakdown in electrical equipment and cables | Variation in capacitance and resistance between wires | Environmental Problems: Contamination Moisture and electric field expansion, Arc tracking, thermal aging, overload | Periodic check on installation will help reduce the risk of occurrence |
2 | Harmonic distortion | Breakdown of inverter or rectifier | Overheating in conductor, transformer or induction motors. Possible failure of power correction capacitor | Neutral conductor size can be increased. The use of harmonic filters |
3 | Power Surge | Equipment damage | Lightening, Overvoltage (e.g. due to reduction in subsea loads) | A surge arrester or protector with an indicator light is highly recommended. Use of voltage regulator in equipment. Uninterrupted power supply will prevent surge |
