IEC 60092-501:2013(E) specifies requirements for all electric propulsion plants and gives the specifications, system design, installation and testing of at least:
- generators and their prime movers;
- switchboards;
- transformers/reactors;
- semiconductor convertors;
- propulsion motors;
- excitation systems;
- control, monitoring and safety systems;
- wires, cables, busbars, trunking systems;
- harmonic filters.
Bow and stern thrusters intended as auxiliary steering devices, booster and take-home devices, all auxiliary generating plants, and accumulator battery powered propulsion machinery and equipment are excluded. This fifth edition cancels and replaces the fourth edition published in 2007. It constitutes a technical revision. This edition included the following significant technical changes with respect to the previous edition:
a) requirements regarding system responsibility, electromagnetic compatibility (EMC), harmonic distortion and filtering, special requirements for ships with propulsion motor(s) and podded drives, and power management system (PMS);
b) overall technical review to update the standard according to general requirements and referenced equipment standards.
