CSCA0200A000B15B01 Open-loop Industrial Current Sensor For Industrial Automation Power Systems
CSCA0200A000B15B01 Open-loop Industrial Current Sensor For Industrial Automation Power Systems
Working Principle:
CSCA-A series open-loop current sensors are based on the Hall effect principle. When current flows through the primary conductor, it generates a rotating magnetic field around the conductor. This magnetic field is collected and concentrated in the air gap of a magnetic core made of magnetosensitive material. The Hall Effect Device (HED) is positioned in this air gap, so the output of the HED is proportional to the amplitude and phase of the primary current. After gain and offset calibration, the sensor provides a preset output sensitivity relative to the primary current.
Application Fields:
- Industrial Automation: Used for monitoring and controlling current in various industrial equipment (e.g., motors, frequency converters, drivers) to ensure normal operation. It can detect faults such as overloads and short circuits in real time, safeguarding production stability and safety.
- Power Systems: In power transmission and distribution systems, it monitors current in transmission lines, switchgear, transformers, etc., enabling real-time monitoring and fault diagnosis to improve power system reliability and efficiency.
- New Energy Sector: In solar photovoltaic and wind power generation systems, it monitors battery charge/discharge current, inverter output current, etc., to optimize new energy generation management and energy control.
- Transportation: In electric vehicles, electric trains, and other vehicles, it monitors battery charge/discharge current and motor drive current, playing a key role in vehicle energy management, performance optimization, and safety protection.
