HMI system

Monitor is LCD with 128X64 matrix, Chinese language, display the time, inside temperature, hiện hành, điện áp, harmonic parameters at real time, check other parameters, operation status through keys, also the values of over-voltage, dưới- điện áp, dưới dòng điện, quá nhiệt độ, over-compensation can be set and saved, data not lost in case of power failure.

Intelligent connection with power system

The product provides RS485 port, giao thức MODBUS-RTU tích hợp, compatible with DL645-2007 protocol, able to perform remote monitoring and controlling. When more than one product connected with system, they will have one master machine among them automatically, others as slave machines, become automatic control system of reactive power compensation, any of individual one has fault, it will stop running, does not influence on others operating; if the master machine has fault and out of operation, they will produce new master machine automatically, form a new system.

Power capacitor

Hi-performance dry type cylinder-shaped self-healing power capacity, has the merits of well radiation, kích thước nhỏ, tuổi thọ dài, ensure the safety and reliability.

Fused disconnector

The general switch cooperated with high breaking fused disconnector is able to break 120KA short circuit current, large break position, to ensure the product able to isolate from system quickly and safely.
