The principle of insulation resistance of aviation plug
What is the principle of the insulation resistance of the aviation plug? We know that the insulation resistance refers to the resistance value that a voltage is applied to the insulation part of the aviation plug and socket connector, so that the surface or the inside of the insulation part generates a leakage current.
That is, the insulation resistance (MΩ) = the voltage applied to the insulator (V)/leakage current (μA).
Through the insulation resistance test, it is determined whether the insulation performance of the aviation plug meets the requirements of circuit design or when it is subjected to environmental stress such as high temperature and humidity, and whether its insulation resistance meets the relevant technical conditions.
Insulation resistance is the limiting factor in designing high impedance circuits. Low insulation resistance means high leakage current, which will destroy the normal operation of the circuit. For example, the formation of a feedback loop, the heat generated by the excessive leakage current and the direct current electrolysis will damage the insulation or degrade the electrical performance of the aviation plug.
