Title:
TRANSMISSION DEVICE OF CURRENT SIGNAL IN SOLAR STRING
Document Type and Number:
Japanese Patent JP2018007382
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently specify a fault location by improving an SN ratio of a current signal that is superimposed on a power line to be transmitted.SOLUTION: A current source 151 is connected to a power line 11 so as to be in parallel with a solar cell element 14. A controller 152 generates a current signal by controlling a current value in the current source 151. A bypass capacitor 153 is connected to the power line 11 so as to be in parallel with the solar cell element 14 and the current source 151. Thus, the bypass capacitor 153 can transmit a current signal transmitted from a negative electrode side in a solar string to a positive electrode side.SELECTED DRAWING: Figure 2
