WGB-603A is a measure and control device designed for substation automation systems operating below 35kV. It serves as a general measure and control unit, featuring measurement, control, monitoring, and recording functions. The device can be installed directly in high voltage switch cabinets or within a screen body. It offers flexible configurations, including WGB-603A/R1 through WGB-603A/R6, tailored for specific applications.
WGB-603A Measure and control device mainly applies to the measure and control unit of interlayer for
substation automation system below 35kV voltage class, and also can be used as general measure and control
device by oneself. The device has measurement, control, monitoring, record and other functions. It can be directly
installed in the high voltage switch cabinet or installed in a screen body. It can be flexible configured as
WGB-603A/R1, WGB-603A/R2, WGB-603A/R3, WGB-603A/R4, WGB-603A/R5, WGB-603A/R6 according to
