The most expensive moment on a ship is the first 10 microseconds after a fault

When we talk with shipowners about power systems, the conversation often starts around efficiency, fuel savings or emissions. These are certainly very important topics, but when you work closely with DC systems, you learn very quickly that the real cost of a power system isn’t decided during normal operation. It’s decided the moment something goes…
