Power station is an important composition of a ship. Ship motor relay-protection equipment is an importance guarantee for safe power supply of ship power system. In order to realize experimental education innovation, we inquire into the experimental equipment of ship motor relay-protection. It will make student, who are major in maritime engineering , know the equipment of ship motor relay-protection and the mechanism of air circuit breaker better. Then they will be persons who are accord to the STCW78/95 pact. On the other hand this research will be powerful quest for computer-controlled ship motor relay-protection testing equipment.
