458 Words2 Pages Dielectric withstanding voltage The purpose of this test is to prove that a connector can operate safely at its rated voltage and will be able to withstand momentary over potentials due to switching, surges and other similar phenomena. The applied voltage can be either AC or DC. The voltage should be applied across the two closely spaced contacts as well as between a connector shell and the contacts closest to the shell. The test voltage in the case of coaxial connectors shall be applied between the inner and outer conductor. The voltage should be ramped up uniformly from zero to rated value. The test can be performed at various pressures depending on the application in which the connector is going to be used. For example, in undersea application the pressure will be high on the connectors. [26] 7.4.2 Insulation Resistance Testing…show more content…
[26]. The insulation resistance is measured using a mega ohm bridge or a mega ohm meter. An applied DC voltage is used to measure the insulation resistance of the connectors in kΩ, MΩ, or GΩ. If the connector is going to operate at special conditions, then the environmental requirements needs to be incorporated. The electrical insulation begins to age as soon as it is installed, this deterioration can affect the performance. It is used as quality control during production of the connector, preventive maintenance tasks and as a troubleshooting
