Process instrumentation is a branch of engineering, which deals with various types of instruments to record, monitor, indicate and control

Synchroscope instrument is used to synchronize two alternators, which are to be connected in parallel with one another with bus

The De Sauty’s bridge is used to measure a capacitance by comparing it with another known/standard capacitance. The circuit has

In the Wein bridge, an inductance is measured by comparison with a standard variable capacitance.

Hay’s Bridge is also used for the measurement of inductance. It uses a standard capacitor in series with a resistance.

Every inductor has a certain amount of resistance, which is undesirable as it causes a power loss. The ratio of

Schering Bridge is the most popularly used bridge for measurement of unknown capacitance and dielectric loss occurring in the capacitor.

Owen’s Bridge bridge is used for measurement of inductance in terms of a standard capacitance. The Fig. 1 shows the
