Shivani Scientific Industries Interview Questions and Answers for Experienced

3 phase power has three conductors carrying three alternating currents, while 1 phase power has only one conductor carrying one alternating current.

• 3 phase power is more efficient for high power applications

• 1 phase power is commonly used in residential buildings

• 3 phase power provides a more balanced power supply compared to 1 phase power

kW is a unit of real power while kVA is a unit of apparent power in electrical engineering.

• kW stands for kilowatts and represents the actual power consumed by a device or system.

• kVA stands for kilovolt-amperes and represents the total power in an electrical system, including both real and reactive power.

• The difference between kW and kVA is due to the presence of reactive power in the system.

• In an ideal system with unit...read more

Transformer works on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.

• Transformers consist of two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field around it.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy between...read more

Types of AC motors include induction motors, synchronous motors, and brushed and brushless DC motors.

• Induction motors: most commonly used type, simple design, reliable, low cost

• Synchronous motors: maintain constant speed, used in applications requiring precise speed control

• Brushed DC motors: use brushes to conduct current, simple design, easy to control speed

• Brushless DC motors: more efficient, longer lifespan, no brus
