Synchronous check relay
WebRotor Earth Fault Protection By Using High Resistance. In this method, a high resistance is connected across the field winding of the rotor.The midpoint of the resistor is grounded through a sensitive relay. When the fault occurs the relay detect the fault and send the tripping command to the breaker. The major disadvantage of such type of ... WebA synchronous serial interface always pairs its data line(s) with a clock signal, so all devices on a synchronous serial bus share a common clock. This makes for a more straightforward, often faster serial transfer, but it also requires at least one extra wire between communicating devices. Examples of synchronous interfaces include SPI, and I 2 C.
