    Dielectric loss tester is mainly used to test dielectric loss, which refers to the energy loss inside insulating materials due to hysteresis effect under the action of electric field. Next, let's specifically discuss the knowledge related to dielectric loss tester and dielectric loss.

    The dielectric loss we usually refer to actually has three types: loss caused by leakage conduction, loss caused by polarization of dielectric, and loss caused by partial discharge. Under DC voltage, the loss in dielectric is mainly leakage conduction loss, which can be indicated by insulation resistance or leakage current. Therefore, the dielectric loss usually discussed is aimed at the loss in dielectric under AC voltage. Under alternating electric field, the complementary angle of the angle between the current phasor and voltage phasor flowing through the dielectric is called the dielectric loss angle. The tangent of dielectric loss angle, also known as dielectric loss factor, refers to the tangent value of dielectric loss angle. According to derivation, when the dielectric, applied voltage and its frequency are constant, the dielectric loss is proportional to the dielectric loss factor, so the dielectric loss factor can be used to indicate the magnitude of dielectric loss. In engineering, the dielectric loss is expressed by measuring and calculating the dielectric loss factor value. Dielectric loss tester refers to a new type of instrument that uses bridge principle and digital measurement technology to actively measure the tangent value of dielectric loss angle and capacitance. It generally includes three parts: high-voltage bridge, high-voltage test power supply, and high-voltage standard capacitor. The method of using external high-voltage test power supply and standard capacitor for testing, and calculating the indication value of the dielectric loss tester according to a certain proportional relationship to obtain the measurement result.
