What Causes Harmonics in Marine Applications? Power electronics with rapid and frequent variations of is damaged. Motors are at risk of overheating and loads provide many process-related control and energy becoming noisy, and torque oscillations in the rotor can saving benefits, leading to the growing abundance of result in mechanical resonance and vibration. If a capacitor these types of devices on board vessels and in offshore overheats, in the most severe cases, the breaking down of marine applications. the dielectric creates an explosion risk. Additionally, the However, these non-linear loads...

Global Solution: Electrical System Level Active Filter The active filter monitors the mains current to determine the amount of harmonic current correction that must be injected to create a sinusoidal AC current and minimize the harmonic current. An active filter is installed parallel to the inverters with the CT on the mains feeder to effectively compensate for harmonics to the 50th order. Figure 4: Simplified illustration of an active filter Active Filter Advantages • Highly effective ◦◦2nd to 50th orders cancelled • Connected in parallel ◦◦Not critical for equipment operation • Scalable parallel...
