Electrical Testing
The AQSCERT facilities are furnished with a wide variety of electrical test equipment to verify the operating conditions of electronic components, assemblies, and products under various types of environmental conditions. Offering a full turnkey solution for your electronic and electrical testing needs. We have the expertise to provide you the information you require whether it involves active monitoring as part of a larger test program or instead stand-alone analysis of a component, board or device. Material properties such as resistance, capacitance and inductance can be determined in addition to the electrical parameters of current and voltage.
- Arc Resistance – The intent of the Arc Resistance test is to make a relative distinction between solid electrical insulating materials. The ability of the test specimens to resist an arc at a high voltage but with a weak current in the vicinity of the insulating surface is investigated. The test focuses on the time until tracking paths start to form.
- Dielectric Breakthrough/Strength – Dielectric breakthrough refers to the highest intensity of an electric field that a material can withstand without losing its composition, while Dielectric Strength refers to the lowest intensity of an electric field at which a material breaks down.
- Dielectric Constant – The capacity of a substance to keep electrical energy in proportion to the permittivity of the surrounding space is the dielectric constant. When the constant intensifies but other factors stay the same, the electric force field grows in density. Under these conditions, an object of a specific weight and measurement can hold an electric charge — as well as greater amounts of charge — for lengthier time spans. Capacitates of high value are among the materials that benefit from having high dielectric constants.
- Surface Resistivity – This is the ratio of DC voltage between the length and width of an object’s surface. Surface resistivity is among the characteristics of a given material that can be studied and assessed in order to determine the overall value of the material — which can also be compared and contrasted with the resistivity of other materials. Overall, the testing process aids in the selection of materials.
- Volume Resistivity – The volume resistivity is an inherent quality that measures how intensely a certain substance contradicts the direction of electric currents. Low-level resistivity suggests that the substance will easily permit the flow of an electric charge. The unit of resistance is known as the ohm, which is symbolized by the letter “R”. If a one-ampere current goes through a part where the voltage could be at least one volt different, the resistivity of that part is one ohm.
- Conductivity – The conductivity of an item is the level at which matter carries out electricity, such as in the rate that heat manages to travel from one point on a given object to another. If a one-ampere current goes through a part in which one volt is present, that part has a conductivity of one Siemens. In most cases, when the voltage application is steadily maintained, the CD circuit will have a relative current to the conductance. If the latter is twice as much, so too will be the current. Likewise, a 1/10 conductance will correlate to a 1/10 current.
- Thermal Coefficient of Resistance – A thermal coefficient refers to the difference in physical makeup of a substance once it has undergone a shift in temperature. Coefficients are identified for numerous processes, such as reactivity and the magnetic and electric attributes of substances. If the resistance level to electrical currents in a piece of material goes up in light of heightened temperature, it’s referred to as positive temperature coefficient (PTC).
