Traction Inverter
In the traction system of rail transit, current sensors are used to monitor the current of traction motors. By monitoring the working current of the motor in real-time, the current sensor can achieve precise control of the motor, thereby improving its operational efficiency and reliability. At the same time, it can also detect the fault current of the motor, such as overcurrent, short circuit, etc., and timely trigger the protection device to effectively prevent motor damage and ensure the safe operation of the train. The current sensors from Chipsense could be used in the traction system field,, we’ve got a positive feedback from our customers in this field.
Brake Chopper
In energy management systems such as brake choppers, current sensors also play a critical role. It can help achieve efficient utilization of energy and ensure the safe and stable operation of the system. By accurately measuring the current, the current sensor provides critical data for the control and protection of the chopper, thereby ensuring the reliability and safety of the entire system.
