Q1. What is the Transformer
Ans. 
A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two coils of wire (primary and secondary) wound around a core

• Primary coil receives electrical energy and produces a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy to the load

• Used to step up or step down voltage levels in power

Q2. Types of DC motor
Ans. 
Types of DC motors include brushed DC motors, brushless DC motors, and stepper motors.
• Brushed DC motors have a rotating armature connected to a commutator and brushes for switching current.

• Brushless DC motors use electronic commutation instead of brushes for switching current.

• Stepper motors move in precise increments, making them suitable for applications like 3D printers and CNC machines.

Q3. Apparatus for Under ground cable test
Ans. 
Apparatus for underground cable test includes cable fault locators, time domain reflectometers, and insulation resistance testers.
• Cable fault locators are used to pinpoint the exact location of faults in underground cables.

• Time domain reflectometers measure the length of the cable and locate any impedance mismatches.

• Insulation resistance testers check the insulation integrity of the cable to prevent electrical leakage.

Q4. Safety devices used on overhead line
Ans. 
Safety devices used on overhead lines include insulators, lightning arresters, and earthing systems.
• Insulators prevent current from flowing to the ground through the supporting structure.

• Lightning arresters protect the line from lightning strikes by diverting the surge of electricity to the ground.

• Earthing systems provide a path for fault currents to safely dissipate into the ground.

• Other safety devices may include bir...read more
