Electrical safety for ships, mobile and fixed offshore platforms
... The unearthed electrical system is continuously monitored by an ISOMETER®. Connected between the active conductors and earth (ship’s hull), it superimposes a measuring voltage on the system. If an insulation fault occurs, the measuring circuit is closed and a small measuring current will flow. This ...

... Third harmonic neutral undervoltage protection covers the final 15% of the stator winding and, in conjunction with the other ground fault elements, provides 100% ground fault protection for the stator. This is supervised by a three phase undervoltage element. Additional supervision using three phase ...
