A protection arrangement for a two-stroke internal combustion engine providing power to a generator

A protection arrangement of a two-stroke internal combustion engine providing power to a synchronous or asynchronous generator having output lines with first circuit breakers, the protection arrangement comprising an engine speed/load control system having an overspeed protection function, wherein the protection arrangement further a secondary overspeed protection system, which comprises a heat resistor bank and a second circuit breaker for each output line, the second circuit breaker being connected to the output line with the first circuit breaker of the same output line, and the heat resistor bank being connectable to the each output line, via the second circuit breaker of the output line;

• the secondary overspeed protection system further comprising a control unit having connections to the first circuit breakers and the second circuit breakers, in order to monitor the first circuit breakers and to control the second circuit breakers, and also a connection with the engine speed/load control system;
• and
• in case the first circuit breaker of at least one output line is tripped to open, the control unit is arranged to control the second circuit breakers of the output lines to connect the heat resistor bank to output lines.
