Provided is a system for protecting a fresh water supply line. According to an embodiment of the present invention, the system for protecting a fresh water supply line, in a system for protecting a fresh water supply line for detecting damage to a heat exchanger for exchanging heat between fresh water in the fresh water supply line and seawater in a seawater supply line to protect the fresh water supply line, comprises: a pair of detectors installed in the inlet part and the outlet part of one or more supply lines from among the fresh water supply line and the seawater supply line to detect one or more from among salinity, conductivity, and electric resistance of the fresh water flowing in each part; and, a controller for blocking the fresh water supply line and the seawater supply line when one or more differences are found among the salinity, conductivity, and electric resistance of the fresh water or the seawater as detected by the pair of detectors. |
