| Abstract: | An intelligent electronic over loadprotective relay is introduced in detail. This electronic overload protective relay takes the different permutations and combinations of current amplitude, positive sequence component, negative sequence component, zero-sequence component and voltage amplitude as protection criterions, and takes PIC 16F877 single-machine as a core part. It can finish the functions of automatic diagnosis of many kinds of failures such as overload, short phase and short circuit and serial communications. So it can meet intelligent need of electrical motor protection. |
