[Core Function]
This device simultaneously undertakes tasks such as feeder protection, transformer protection, capacitor bank protection, motor protection, measurement monitoring, and sequence control. Built in dual processor architecture: one processor is dedicated to ultra fast protection algorithms (with a trip time of less than 25 milliseconds), while the other processor manages communication, HMI interaction, and data recording, without preempting resources. The protection function blocks are independent of each other, each with its own set of fixed values and data records. In addition to protection, measurement, control, and status monitoring, it also provides rich PLC programmable logic functions, which can integrate the automation and sequential logic control required for substation automation into one device, greatly reducing the need for on-site hard wiring.
