BH916 dielectric loss test device (Shu Xian)
Dielectric loss test device and the C BH916D Q table and the inductor with theinsulating materials, high frequency dielectric loss tangent (tan delta) and Permittivity(epsilon) test. It accords with the national standard GB/T 1409-2006, GB/T 1693-2007, American Standard ASTM D150 and IEC60250 specifications.
The testing device is composed of a micrometer capacitor plate, plate capacitor is usually used to clamp the sample, equipped with the Q table as indicating instrument.Insulating material loss angle tangent value is calculated by the formula of scale reading changes through the tested sample into the panel capacitor and do not put it in the samples of Q value change and the thickness of the obtained. Similarly, thescale reading changes of the panel capacitor, to obtain the dielectric constant is calculated by a formula.
