Q2. Why machines ratings are in kVA instead of kW
Ans. 
Machines ratings are in kVA instead of kW due to the presence of reactive power.
• kVA represents the apparent power of a machine, which includes both real power (kW) and reactive power (kVAR).

• Reactive power is required by machines with inductive or capacitive loads to create magnetic fields or store energy.

• kW represents the actual power consumed or produced by a machine, while kVA represents the total power required to p...read more

Q3. How single phase machines are designed
Ans. 
Single phase machines are designed by using a single phase power supply and incorporating specific design elements.
• Single phase machines use a single phase power supply, typically from a residential or commercial electrical system.

• They are designed with specific components such as a single phase winding, a capacitor for starting, and a centrifugal switch for switching between starting and running modes.

• Examples of sing...read more

Q4. How transformer breath and what material used in this system?
Ans. 
Transformers breathe through cooling systems and use materials like oil or air for insulation.
• Transformers have cooling systems to dissipate heat generated during operation.

• The cooling system can be either oil-based or air-based.

• Oil-filled transformers use oil as a cooling and insulating medium.

• Air-cooled transformers use fans or radiators to cool the windings.

• The cooling system ensures the transformer operates within

Q6. What is HG fuse and how does it works
Ans. 
HG fuse is a high-grade fuse used in electrical systems to protect against overcurrents.
• HG fuse stands for High-Grade fuse.

• It is used in electrical systems to protect against overcurrents.

• It works by melting a fuse element when excessive current flows through it.

• The melting of the fuse element breaks the circuit and prevents damage to the electrical system.

• HG fuses are commonly used in industrial applications and power

Q7. What is the use of CT/PT
Ans. 
CT/PT are used in electrical systems to measure and protect against high currents and voltages.
• CT (Current Transformer) is used to measure high currents and step them down to a manageable level for measurement or protection devices.

• PT (Potential Transformer) is used to measure high voltages and step them down to a safe level for measurement or protection devices.

• CTs and PTs are commonly used in power systems, electrica...read more
