Tangens-3M3 tan delta oil tester

الوصف

The dielectric loss measurement device Tangens*3M*3 is designed to measure the dielectric loss tangent (tan delta) of transformer oil  and several other liquid dielectrics.
Under the normal conditions, the device Tangens*3M*3 provides the measurement of the dielectric loss tangent (tgδ)and the capacity of liquid dielectric samples (Сх)in the ranges with basic measurement error given below:
· measurement range of dielectric loss tangent from 1·*0*4 to 0.*9;
· limit of permissible absolute basic error when measuring the dielectric loss tangent1)  +(2·*0*4 + 0.*5 tgδ)%;
· range of capacity measurement at a test voltage  from 1.5 to 2 kV from 5 pF to **0 pF;
· limit of permissible basic error when measuring the ­capacity at a frequency of *0 Hz 1 pF*0.*1Сх;
