Problems solved by technology

[0006] However, when estimating the corrosion rate of a metal material at a location (non-measurement point) where no such measurement has been performed (non-measurement point) based on the data of the measurement of the corrosion rate of the metal material, when there is a special corrosive environment at the non-measurement point, there is an inference The case where the accuracy of the
That is, in a place with a special corrosive environment, the measurement by the ACM sensor is performed first and then the specific value is measured, so the estimated result may deviate

Abstract

A corrosion assessment method according to one embodiment of the present invention is for making an assessment regarding corrosion of a metallic material on the basis of the result of measurement performed by using a detector concerning corrosion, the method comprising: acquiring a first measurement result of a first detector installed at a first measuring point; acquiring a second measurement result of a second detector installed at a second measuring point different from the first measuring point; and acquiring a deduction result obtained by deducing information about a measurement result ata deduction point different from the first and second measuring points on the basis of the first measurement result.

Description

technical field [0001] The present invention relates to a corrosion evaluation method. Background technique [0002] Electrical equipment is sometimes constructed using metallic materials. As such electric power equipment, there are, for example, transformers, steel towers, bridges, or electric wires made of steel, galvanized, or aluminum. Towers hold power lines, etc. Such electric power equipment may be installed outdoors, for example, and may be scattered over a wide area. [0003] It is very important to evaluate the corrosion rate of metal materials constituting electrical equipment, and maintain the electrical equipment properly and efficiently. Recently, an ACM (Atmospheric Corrosion Monitor) sensor, which can quantitatively evaluate the corrosion rate in a shorter time and more easily than an exposure test, monitors the atmospheric environment and evaluates the corrosion rate. [0004] As an example, Patent Document 1 describes a corrosion rate evaluation method,...
