In normal operation, the circuit can be switched on or off by means of a manual or automatic switch. When the fault or abnormal operation occurs, the circuit is cut off or an alarm is given by the aid of the protective electric appliance. The measuring instrument can display various parameters in operation, and can also adjust some electrical parameters to prompt or send out signals for deviation from normal working state. An encoder is a device that compiles, converts, and/or formats signals or data into a form of signals that can be communicated, transmitted, and stored. Encoders convert angular or linear displacements, called codewheels, into electrical signals, called coderulers. The encoder can be divided into a contact type and a non-contact type according to a reading mode; encoders can be classified into an incremental type and an absolute type according to their operation principles. The incremental encoder converts displacement into periodic electrical signals, and then converts the electrical signals into counting pulses, and the number of the pulses is used for expressing the magnitude of the displacement.
