Site Authorisation Services Ltd

Blueferrite is a brand that produces high quality Nanocrystalline Cores, which reduce EMC Noise and related problems. If all drivetrains with variable frequency drives are equipped with Blueferrite-Nanocrystalline cores, the leakage currents at the factory grid can be reduced to a harmless level. This will solve unexpected triggering of protective devices and motor bearing damage caused by circulating or rotor-to-ground bearing currents. Our cores are specially designed for electrical drives to withstand high load currents without going into saturation. 

There are several issues or effects that can be identified as having arisen from EMC Noise. These include, but are not limited to, hull corrosion due to leakage currents or hull currents, motor bearing issues, sensor issues, as well as burning out of capacitors used for noise filtering. Apart from these issues, there are several issues created by the EMC noise created by switching, even when the ship is docked at the harbor and the batteries on board are being charged.

Site Authorisation Services are the UK Distributor for Blueferrite and we can undertake Motor & Inverter surveys, EMC checks / transient / Power Quality surveys and assist with the installation of Blueferrite cores -  the only solution to protect against harmful common mode interference.
