Diesel Generator Protections. A Quick Check for an Inspector

Greetings! In this article, I recommend that you familiarize yourself with the main protections of diesel generators on a ship, which inspectors like to check. There are many protections on ship diesel generators and one article is not enough to consider them all, so only the main protections will be described, which are most often demonstrated when passing a particular check.

Using the example of the Daihatsu 6DE-18 diesel engine and the Taiyo FE 647A-8 brushless synchronous generator, we will consider the protection of marine diesel generators and how to test them. Other most common diesel engines (Himsen, Yanmar, MAN B&W) found in the merchant marine fleet will also be partially covered.
