Measuring Capacitance: The Schering Bridge measures capacitance by adjusting the impedance of its components to balance the bridge, where no voltage is detected across specific points.
The Schering bridge is one the most popular bridges that are used to measure unknown capacitance. Since, the Schering bridge is a type of AC bridge, hence it also works on the same principle as the other ac bridges do.
Capacitor Under Test (CuT): The capacitor whose capacitance is to be measured is connected to one arm of the bridge. Standard Capacitor (Cs): A known and calibrated capacitor is connected to another arm of the bridge. Variable Resistance (Rv): A variable resistor is connected in parallel with the standard capacitor to ensure balance in the bridge.
High voltage Schering bridge is the most suitable method for measurement at high voltage because of the following reasons, The results obtained using the Schering bridge for high voltage measurement will be very accurate. The circuit incorporates a vibration galvanometer as a detector which is highly sensitive.
The schering bridge can be employed to determine the relative permeability (μr) of magnetic materials. It involves measuring the capacitance Cs of a material sample and relating it to μr using the formula: εr = Csd ε0A ε r = C s d ε 0 A Where, Cs is the measured value of capacitance by considering the specimen as a dielectric.
One widely-used method for measuring capacitance with high precision is the Schering Bridge, a balanced bridge circuit that exploits the principles of impedance to yield accurate capacitance readings.

What is De Sauty''s Bridge? Theory, Diagram & Derivation
Advantages of De Sauty''s Bridge. It is very simple circuit. The calculations are also easy. Disadvantages of De Sauty''s Bridge. If both the capacitors are not free from dielectric loss then it is not possible to obtain the balance condition.
