PROBLEM TO BE SOLVED: To provide a slave station for an automatic voltage regulator, capable of continuing its operation as a voltage relay even if a lightning surge breaks a communication function.SOLUTION: The slave station for an automatic voltage regulator includes: a communication circuit board 23 electrically connected with a remote control cable 19; a control circuit board 27 having a function that remote controls an automatic voltage regulator body 3 on the basis of a remote control signal from a communication circuit and a function that controls the automatic voltage regulator body 3 by autonomous operation in the absence of the remote control signal; and a power supply, all of which are stored in a storage case 21. The power supply includes a power supply 25 for communication circuit and a power supply 29 for control circuit configured to be electrically insulated, respectively, and the communication circuit board 23 and the control circuit board 27 are connected to be mutually communicable in an electrically insulated state. |
