The purpose of wet leakage current test system is to test the insulation performance of components under wet working conditions, and verify that the moisture of rain, fog, dew, water or snow cannot enter into the components and affect the circuit.
The key part of wet leakage current test system includes: high precision sensor automatic test: measuring surface tension and interfacial tension, digital display of measured value, automatic reading and display of measured value of balanced surface tension, without any additional equipment. It can measure the change of surface tension caused by time change (especially when there is surfactant). It can automatically measure medium to high viscosity liquid samples and get equilibrium results. It can measure the interfacial tension between immiscible liquids. The operation is simple, and platinum plate or platinum ring can be used. Platinum ring method is optional and needs manual conversion.
