Photovoltaic Inverter Current Measurement
In photovoltaic power generation systems, current sensors monitor the DC current output from solar panels to the inverter. High precision current sensors with 10ppm accuracy enable accurate MPPT control, optimizing energy conversion efficiency under varying irradiance conditions. The AIT series large current sensors, with measurement ranges up to 8000A, are ideal for utility-scale PV inverters where high current capability and precision are equally critical.
Wind Turbine Converter Current Monitoring
Wind turbine systems require current sensors for generator output monitoring, converter control, and grid synchronization. The fluxgate technology provides superior accuracy compared to traditional Hall-effect sensors, with temperature drift as low as 0.1ppm/°C. This precision is essential for variable-speed wind turbines where power electronics must handle fluctuating wind conditions while maintaining grid compliance.
