Get a quote4 FAQs about [Leakage in photovoltaic energy storage cabinet and electric cabinet]
How does photovoltaic system generate leakage current?
When the photovoltaic system regenerates power, it will also generate leakage current, also called common mode current. This is due to the parasitic capacitance between the photovoltaic system and the ground. At this time, a loop is formed between the power grid, the photovoltaic system, and the parasitic capacitance.
What are the characteristics of photovoltaic leakage current?
The leakage current of the photovoltaic system has two characteristics: 1. The leakage current is complicated, divided into DC part and AC part; 2. The current secondary value is very small, all in the milliampere level, which requires extremely high accuracy and requires a dedicated current sensor.
What are the risks of photovoltaic systems?
The leakage current generated by the photovoltaic system generally includes both the DC part and the AC part. When it is connected to the grid, it is very easy to cause electromagnetic interference and other problems, which not only damages the equipment in the grid, but also may cause electric shock hazards to users or staff.
What is the leakage current pathway from the glass/polymer interface?
The leakage current pathway from the glass/polymer interface has the least resistance providing a negative current. Similarly, the charge at the AR coating to polymer interface, QAR, is also flowing out through the metallization but in this case contributes as a positive current because of the instrument configuration.
