System comprising a spacecraft and method for determining an electrical phenomenon of a solar generator

A system, comprising:

• a spacecraft with:
• at least one solar generator capable of generating an electric current, each solar generator being covered by a transparent protective material, each solar generator comprising a plurality of sections;
• at least one electrical energy consumer, with each solar generator being capable of supplying the electric current to at least one electrical energy consumer of the spacecraft;
• at least one pair of electrical conductors associated with each section, to supply the electric current from each section of each solar generator to the respective electrical energy consumers, the pairs of conductors comprising at least one conductor for each polarity;
• wherein:
• the spacecraft comprises, for each section associated with at least one pair of conductors, at least one sensor to measure a value depending on the current(s) in the conductors;
• and
• the system comprises at least one device for detecting an electrical phenomenon of the solar generator, the device for detecting an electrical phenomenon being capable of:
• determining a common mode current for each section and/or the derivative of the common mode current for each section, and
• determining the presence of an electrical phenomenon and the section(s) of the solar generator affected by the electrical phenomenon determined from the common mode current of each section and/or the derivative of the common mode current of each section.
