Vitromed Healthcare Interview Questions and Answers for Experienced

Q1. 3 phase and 1 phase different
Ans. 
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

Q2. Kw and kva different
Ans. 
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

Q4. Transformer work of principle
Ans. 
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

Q2. What is Motor working process
Ans. 
The motor working process involves converting electrical energy into mechanical energy.
• Electricity is supplied to the motor, which creates a magnetic field.

• The magnetic field interacts with the motor's coils, causing them to rotate.

• The rotating coils generate mechanical energy, which can be used to power various devices.

• Different types of motors, such as AC motors and DC motors, have variations in their working process...read more
