Current Sensor Failure Causes And How To Prevent Them
Current sensor failure is often preventable. The main causes include wrong current range, overload current, incorrect wiring, insufficient isolation, output signal mismatch, high temperature, EMI interference, poor grounding, mechanical stress, humidity, and weak installation layout. For motor drives, EV chargers, battery energy storage systems, solar inverters, UPS systems, welding machines, railway systems, and industrial power electronics, buyers should select the sensor according to real operating conditions and verify it before mass production. A correct sensor model, proper installation, reliable wiring, strong isolation, good thermal design, and complete testing can significantly reduce failure risk and improve long-term system reliability.
