LINETRAXX® VMD460-NA

LINETRAXX® VMD460-NA

  • 用于国家标准和法规所默认的基本程序的网络和系统保护
  • 岛屿网络检测df/dt (ROCOF) 位移矢量
  • RS-485接口 (数据交换/参数设置/软件升级)
  • 相电压和线对线电压的连续监视
  • 通过波动控制信号接收器,远程关机

VMD460用于外部网络和系统保护的保护设备(NS保护),其目的是在有未经许可的阈值的情况下,通过耦合开关将电网从发电系统断开。如果在发电系统的电压和频率测量是在标准的阀值要求外,VMD460的继电器会动作 。VMD460是多功能可调的。
当前的测量值会连续不断的显示在液晶显示屏上。保存引起继电器跳闸的测量值。
