場合には短絡の原因となるおそれがある。2. Description of the Related Art Insulating materials used in a charged part of a control panel, a distribution panel, or the like are insulated because ionic substances adhere to and accumulate on the surface due to the installation environment over time. The resistance value decreases. In the worst case, such a decrease in the insulation resistance may cause a short circuit.

高くなったときにも絶縁抵抗値は低くなる。Incidentally, the insulation resistance value varies depending on the ambient temperature and humidity at the time of measurement. FIG. 3 is a diagram illustrating an example of the correlation between the insulation resistance value of an insulator to which an ionic substance is attached at a temperature of 20 ° C. and humidity. The figure shows that the insulation resistance value is high when the humidity is 30% RH, but the ionic substance is more likely to conduct as the humidity increases, so that the insulation resistance value decreases. In particular, an insulator having contaminants adhered to its surface over time becomes more susceptible to the influence of humidity because it easily absorbs moisture, and the insulation resistance value greatly decreases as the humidity increases. Also, when the temperature increases, the insulation resistance value decreases.
