A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction. Testing procedure involves various tests to ensure proper functioning.
Transformers are used to step up or step down voltage levels in electrical circuits.
Testing procedures include insulation resistance test, winding resistance test, turns ratio test, and oil testing.
Insulation resistanc...
Over current is when the current flowing through a circuit exceeds its rated capacity. Earth fault is when current flows to earth due to insulation failure.
Over current can cause damage to equipment and can be a fire hazard.
Earth fault can cause electric shock and damage to equipment.
Both can be prevented by proper installation and maintenance of electrical systems.
Examples of protective devices include fuses, circuit
Electrical protection refers to measures taken to prevent electrical hazards and damage to equipment.
Electrical protection includes the use of circuit breakers, fuses, and surge protectors.
Grounding and bonding are also important aspects of electrical protection.
Electrical protection is necessary to prevent electrical shock, fires, and damage to electrical equipment.
Examples of electrical protection measures include GF...

Electroplating is a process of depositing a metal coating onto a conductive surface using an electric current.
The object to be plated is made the cathode in an electrolytic cell
The anode is made of the plating metal
The electrolyte solution contains ions of the plating metal
When a current is passed through the cell, metal ions are reduced and deposited onto the cathode
Common applications include coating of jewelry, auto
