Wholesale Electric Power Fittings Factors Affecting The Insulation Fittings Resistance Measurement, Mainly Temperature, Humidity and Discharge Time: 1. Due to the increase in temperature, the medium polarization is intensified, causing the electrical conductor, the resistance is lowered, so the insulating resistor is reduced with temperature. 2. Due to the surface of the insulator, the water film is formed on the surface of the ferrule, the insulation resistance is significantly reduced, in addition, when the insulation is larger than having a large relative humidity, more moisture is absorbed, and the electrical conductivity is increased, and the insulation resistance is lowered. 3. The measurement insulation resistance is equivalent to applying a DC voltage on insulation, and thus the measured object is charged. After the measurement is completed, it should be fully discharged, and the discharge time should be greater than the charging time, not due to the residual CHERGE. WHEN THE Measurement IS Repeated, The Resulting Charging Current and The Absorption Current Are Smaller Than The Previous Measurement, and Thus the Absorption Ratio is reduced, and the insulation resistance value increas.Wholesale Electric Power Fittings website:http://www.chinaelectrictelecommunicate.com/electric-power-fittings/
