FSQS-87 High precision automatic tan delta measuring bridge is the basic measurement instrument of capacitance and dielectric loss test, widely used for tan delta of cable type test in factory according to IEC 60840.

It adopts the principle of current comparer, which makes it with high measurement accuracy and reliability, normal schering bridge or HV tan delta tester cannot achieve. Combine with computer data processing, make the measurement more visualized and convenient.

With large TFT screen to display value of capacitance Cx, dielectric loss, test voltage Upk/2, inductance Lx, quality factor Q, test current Ix, dielectric constant of material, test frequency fx, apparent power S, effective power P, reactive power Q and etc.
