MV soft starter
MV soft starter is designed for both squirrel-cage asynchronous and synchronous motors. They integrate motor terminal control functions such as starter, protection, display, and data collection into one piece of equipment. By using fewer components, it allows for more complex control capabilities. The soft starter regulates the input voltage by adjusting the conduction angle of control elements, reducing the electrical and mechanical stress on the power grid, motor, and equipment. Once the motor reaches its rated speed, the bypass contactor automatically activates. The soft starter continually monitors the motor post-startup and provides various fault protection features. They are also an advanced device for motor starting, providing smoother acceleration according to set starting parameters.

Arc extinction and harmonic elimination cabinet
Arc extinction and harmonic elimination cabinet During regular functioning, the microcomputer controller constantly monitors the voltage signal received from PT. Suppose the system experiences PT disconnection, single-phase metal grounding, or single-phase arc grounding. In that case, the auxiliary secondary open triangle voltage will promptly shift from a low to a high level. The microcomputer controller will then activate. It will determine the type and phase discrepancy based on the alteration in the PT secondary voltage
