RY2 type solid insulation material test electrodeDetailed product description：

The RY2 solid insulation material test electrode is manufactured as a flat plate type three terminal capacitor with a protective electrode. It can be used to measure the dielectric loss factor and relative dielectric constant of various solid insulation materials (such as polystyrene, polypropylene, capacitor paper, mica sheet, etc.) under the conditions of pressure, heating, and vacuum pumping, and equipped with a high-voltage capacitor bridge at the power frequency voltage.

The electrode design is a flat plate type three terminal capacitor with a protective electrode. The dielectric loss angle δ of the insulation material is the residual angle of the phase difference between the voltage applied to the capacitor with the insulation material as the dielectric and the current flowing through the capacitor. The dielectric loss factor of insulating materials is the tangent value of the dielectric loss angle δ, which is denoted as tg δ. When a sheet-like sample of insulating material is placed in the middle of an electrode and a certain pressure is applied, it can be regarded as a capacitor with the insulating material as the dielectric. The measurement of capacitance and dielectric loss factor can be carried out on a high-voltage capacitor bridge. The relative dielectric constant ε r of insulating material is the ratio of the capacitor Cx to the vacuum capacitor Co of the same configuration when the space between the electrodes and their surroundings is completely filled with insulating material: ε r=Cx/Co
This electrode is equipped with an RY2-2 temperature controller and vacuum pump, which can measure under heating and inert gas filling conditions.
