BDAT-B型高压电容电桥
主要用于测量高压工业绝缘材料的介质损失角的正切值及电容量。其采用了西林电桥的经典线路。
主要可以测量电容器，互感器，变压器，各种电工油及各种固体绝缘材料在工频高压下的介质损耗( tg)和电容量( Cx)以，其测量线路采用“正接法”即测量对地绝缘的试品。
由于电桥内附有一个2500KV的高压电源及一台高压标准电容器，并将副桥和检流计与高压电桥有机的结合在一起，所以本电桥特别适应测量各类绝缘油和绝缘材料的介损（tg）及介电常数（ε）。
 桥体本身带有5Kv/100pF标准电容,测量材料介损更为方便。
桥体内附电位**及指另仪，外围接线及少。
 桥体采用了多样化的介损测量线路。

Dielectric constant dielectric loss tester details:
One, the dielectric constant dielectric loss tester overview
Dielectric loss and dielectric constant are all kinds of porcelain, porcelain, ceramic capacitor device, and composite materials is an important physical properties, by measuring the dielectric loss tangent of dielectric constant ( Tan δ andε), to further understand the effects of dielectric loss and dielectric constant of the various factors, in order to improve the material the property basis; instrument basic principle is the use of high frequency resonance method, and provides, universal, multi-purpose, multiple range impedance test. It uses single-chip computer as the control core of measuring instrument, using the frequency locking, frequency standard test point automatic setting, resonant point automatic search, Q value range automatic conversion, numerical display and other new technology, improved the tuning circuit, the tuning circuit for testing the residual inductance is reduced to the minimum, and retains the original Q table in the automatic amplitude stabilizer technology, makes the new instrument in the use of more convenient, measurement is more accurate. Instrument in high frequency test conditions, measurement of high frequency inductive or resonant loop of the Q value, the inductance of the inductor is the amount and distribution of capacitance, capacitance and loss angle tangent value of electrical materials, dielectric loss in high frequency, high frequency circuit in parallel and series resistance, the characteristic impedance of the transmission line and so on.
Dielectric constant dielectric loss tester used in scientific research institutions, schools, factories and other units to inorganic metalloid new material property application research.
