NOVELTY - The conduit line corrosion protection system comprises a photovoltaic module for producing power using an energy collected from the sunlight. A battery is charged using the power produced by the photovoltaic module. A required power calculation unit is connected with a conduit line resistance value measurement part that measures the resistance value of a pipeline. A power-on signal generator generates the power-on signal related to a controller. An anti-corrosion power applying part applies anticorrosion power to the conduit line from the battery.    USE - The conduit line corrosion protection system is useful for preventing corrosion of a power source installed in an environment.    ADVANTAGE - The conduit line corrosion protection system can be normally managed in the remote location. The required power consumption of the system is measured according to the length of the conduit line so that the capacity of the battery and the photovoltaic module is improved.    DETAILED DESCRIPTION - The conduit line corrosion protection system comprises a photovoltaic module for producing power using an energy collected from the sunlight. A battery is charged using the power produced by the photovoltaic module. A required power calculation unit is connected with a conduit line resistance value measurement part. A generator is adapted to generate power-on signal related to a controller. A part is adapted to apply anticorrosion power to the conduit line from the battery. A comparison unit cross-compares the power offset measured in a power offset measuring unit. A unit is adapted to generate a power offset confusion signal deviated from a fixed error range based on power offset comparison. A generator is adapted generates a battery changing signal. A radio frequency unit wirelessly transmits the battery changing signal to the remote location. A low voltage transformer reduces the voltage of the anticorrosion power. A constant power part maintains the power applied to the conduit line.
