Transformers are normally protected against short circuits and overheating. Transformer protections justifiable in different installations will vary widely depending upon the size of the equipment, importance as a unit part of the Distribution system, and its voltage rating. Small distribution Transformers maybe protected by fuses while larger ones in feeder circuit or at injection substations may be equipped with various types of protective equipment varying from long-time overcurrent to high speed differential protection, standby earth fault...

Analog Signal Conditioning provides the operations necessary to transform a sensor output into a form necessary to interface with other elements of the process control loop.
Signal Conditioning can be classified into various types:
Linearization
Conversions
Filtering and Impedance Matching
Concept of Loading
Linearization
The purpose of linearization is to provide an output that varies linearly with some variable even if the sensor output does not.
Conversions
Often, Signal Conditioning is used to convert one type of electrical variation...
