In photovoltaic arrays, DC leakage currents may be generated due to the parasitic capacitance existing between photovoltaic modules and the earth, as well as the reduction of insulation impedance caused by environmental factors (such as after rain, humid environment). If these leakage currents are not detected and controlled in time, they may not only damage the photovoltaic modules and inverters, but also pose a safety threat to maintenance personnel. Therefore,now it is essential to accurately and reliably monitor the DC leakage currents in photovoltaic arrays.
Advantages of FR6V H00 Series current Sensor from CHIPSENSE
High-precision measurement: CHIPSENSE FR6V H00 current sensor use fluxgate technology to achieve high-precision measurement of DC leakage current, with a range of 0.01 to 0.1A, meeting the strict requirements of photovoltaic systems for small leakage current detection.
Low zero temperature drift: CHIPSENSE FR6V H00 current sensor has a very low zero temperature drift characteristic, which means that under different temperature conditions, the stability of its measurement results is extremely high, reducing the measurement error caused by temperature changes. All products of CHIPSENSE are produced in strict accordance with standards in this regard.
Safe and reliable: CHIPSENSE raw materials comply with UL 94-V0 standard to ensure the safety and reliability of the sensor during use. At the same time, its high-precision measurement capabilities help to detect and deal with potential leakage problems in a timely manner and avoid safety accidents.
Domestic substitution: As a domestic high-end current measurement sensor developed by CHIPSENSE the FR6V H00 current sensor not only performs well, but also realizes the domestic substitution of imported products, reducing the cost of photovoltaic systems and promoting the development of the domestic photovoltaic industry. CHIPSENSE will continue to improve it.
Applications
In the photovoltaic array, the FR6V H00 current sensors from CHIPSENSE can be installed in key positions, such as the input of the inverter, between the photovoltaic module and the bracket, etc., to monitor the size of the DC leakage current in real time. When the leakage current is detected to exceed the preset threshold, the sensor will issue an alarm signal to remind the maintenance personnel to deal with it in time. At the same time, the CHIPSENSE current sensor can also be integrated with the intelligent monitoring system of the photovoltaic system to realize remote monitoring and automatic control, further improving the safety and reliability of the photovoltaic system.
