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
