变电所内信号装置可反映出电气设备工作状态，预告信号是在某些电气设备出现了不正常运行状态时发出的信号，如断路器合闸、跳闸状态用红、绿灯或位置继电器来反映；隔离开关多用本身带有的位置指示器指示工作状态；发电机运行中的调相状态和发电状态用灯光表示；事故音响信号采用高音笛声，预告信号的音响采用电铃声响。一旦出现异常就会通知运行人员尽快采取措施，进而解除事故信号，使装置复归，保证系统正常运行。
由于大型变电站电气接线较复杂，断路器的数量也较多，通常采用能重复动作的事故和预告信号装置。由于预告信号电路设置0.2～0.3s的短延时，需设冲击继电器，具有冲击自动复归的特性，以避免某些瞬时性故障时，误发信号或某些不需瞬时发出的预告信号。
