High Voltage Schering Bridge

High Voltage Schering Bridge

The High Voltage  Schering bridge one in every of the most normally used AC bridge. The Schering bridge works on the principle of Equal the load on its arm.

Fig. 1 shows where the specimen has been represented by a parallel combination of Rp and Cp.

Let, C1 – capacitor Which capacitance is to be determined,
r1 – a series of resistance, Indicate the loss of the capacitor C1.
C2 – a standard capacitor
R3 – a non-inductive resistance
C4 – a variable capacitor.
R4 – a variable non-inductive resistance

At balance condition

Z1/Z2 = Z3/Z4
Z1Z4 = Z2Z3

Schering Bridge is also Used To Measure

Applications Are capacity and dielectric, loss measurement of all kinds of capacitances, for instance, cables, insulators, and liquid insulating materials.

Dissipation Factor in Schering Bridge

The dissipation factor of a capacitor is that the ratio of its resistance to its capacitive reactance. The Schering Bridge is essentially a four-arm AC bridge and its measurement idea is predicated on balancing the hundreds on its arms.

  D1 = 2π x 50 x 3180 x C4 = C4 X 10

Since C4 is a variable decade capacitance box, it's setting in μF directly gives the value of the dissipation factor. 

Why bridge is used for the measurement of small capacitance

It is suitable for the measurement of small capacitance equipment. as the bridge uses either high voltage or high-frequency provide. If measurements for such low capacity equipment is carried out at low voltage, the results so obtained are not accurate.

Comparison between VSI and CSI

Comparison between VSI and CSI In power electronic systems, inverters are an essential component that converts direct current (DC) into alternating current (AC). There are two main types of inverters used in power electronic systems: Voltage Source Inverters (VSI) and Current Source Inverters (CSI). Both have their own unique advantages and disadvantages, and the choice of which to use depends on the specific application and the desired outcome. Comparisons between voltage source inverters and current source inverters are as follows. In voltage source inverters, the input voltage is maintained constant and the amplitude of the output voltage does not depend on the load. However, the waveform of load current, as well as its magnitude, depends upon the nature of load impedance.  In current source inverters (CSI), the input current is constant but adjustable. The amplitude of output current from CSI is freelance of the load. However, the magnitude of output voltage and its undulation outp

Limitations of Terzaghi Theory

Limitations of Terzaghi Theory The value of the coefficient of consolidation has been assumed to be constant.  The distance d of the drainage path cannot be measured accurately in the field. The thickness of the deposit is generally variable, and an average value has to be estimated.  There is sometimes difficulty 1n locating the drainage face, and sometimes thin previous seams that can act as good drainage faces are missed in the boring operations. The equation is based on the assumption that the consolidation is one-dimensional. In the field, the consolidation is generally 3-dimensional. The lateral drainage may have a significant effect on the time rate of consolidation. The initial consolidation and secondary consolidation have been neglected. Sometimes these form an important part of the total consolidation. In actual practice, the pressure distribution may be far from linear or uniform.
