Measurement and Control Device TY8690 series of protection by the line protection, transformer protection, capacitor

protection, reactor protection, standby power from the cast, composed of motor protection, can be used for 110kV and below voltage levels of various industrial and mining enterprises and power industry. By using a high-performance 32-bit CPU to integrate protection, measurement and control, and communication functions, it is suitable for substation integrated automatic systems or new energy power plant electrical automation systems. Devices can be installed Group centralized screen can also be directly installed in the switch cabinet to carry out decentralized control.
