LINETRAXX® CMS460-D

CMS460系统包括一个或数个CMS460-D负载电流评估仪，通过组合的测量电流互感器，设备能够监视和评估接地和不接地电源的负载电流。被监视系统的最大电压取决用于母线系统中的测量电流互感器的标称绝缘电压，或通过的电缆或导线。

W… (环形), WR… (矩形) and WS… (可拆卸形) 和WF… (柔性)测量互感器用于交直流系统。不同电流互感器的任意组合可以连接到评估的测量通道。每个Each CMS460-D 有12个测量通道。通过BMS总线(带BMS协议的RS-485接口)，最多可以连接90个负载电流评估仪，因而最多可以同事监视1080个测量通道(子回路) 。

如果设备用于防火或者柜体保护，可以相应的设置相应频率。测量电流可以进行谐波分析。
