Q1. WHAT IS VOLTAGE CONDITIOANING, DSP, COMMON MODE REJECTION OF OP AMP

Ans.

Voltage conditioning, DSP, and common mode rejection are important concepts in the operation of operational amplifiers (op amps).

  • Voltage conditioning involves adjusting the input voltage to a level that is suitable for the op amp to process.

  • DSP (Digital Signal Processing) refers to the manipulation of signals using digital techniques, often used in conjunction with op amps for signal processing.

  • Common mode rejection ratio (CMRR) of an op amp is a measure of its ability to rej...read more

Q2. What is the average soil bearing capacity of 2bhk

Ans.

The average soil bearing capacity of a 2bhk depends on various factors such as soil type, depth, and quality.

  • Soil bearing capacity can range from 1,500 to 5,000 pounds per square foot for residential buildings.

  • Factors like soil type (clay, sand, gravel), depth of soil, and quality of soil affect the bearing capacity.

  • Consulting a geotechnical engineer is recommended to determine the specific soil bearing capacity for a 2bhk construction.

Q3. What are the types of induction machines?

Ans.

Types of induction machines include squirrel cage induction motors and wound rotor induction motors.

  • Squirrel cage induction motors have a simple and rugged construction, suitable for constant speed applications.

  • Wound rotor induction motors have external resistors connected to the rotor windings, allowing for adjustable speed and high starting torque.

  • Other types include double cage induction motors and single-phase induction motors.

  • Examples include Siemens SIMOTICS SD100, ABB ...read more

Q4. What type of corcuit breaker is used in your home?

Ans.

A combination of both standard and arc fault circuit breakers are used in my home.

  • Standard circuit breakers are used to protect against overloads and short circuits.

  • Arc fault circuit breakers are used to detect and prevent electrical fires caused by arcing faults.

  • Both types of circuit breakers provide different levels of protection for electrical circuits.

  • Examples: Square D QO series for standard circuit breakers, Siemens QA series for arc fault circuit breakers.

Q5. Explain about the power generation and distribution

Ans.

Power generation involves converting various forms of energy into electrical power, which is then distributed through a network of transmission lines and substations to end users.

  • Power generation involves converting mechanical, chemical, solar, wind, or nuclear energy into electrical power

  • The generated power is then transmitted through high-voltage transmission lines to substations

  • Substations step down the voltage for distribution to residential, commercial, and industrial us...read more

Q7. What are communication modules in PLCs

Ans.

Communication modules in PLCs are hardware components that allow the PLC to communicate with other devices or systems.

  • Communication modules provide various communication interfaces such as Ethernet, serial ports, Profibus, Profinet, etc.

  • They enable the PLC to exchange data with other PLCs, HMIs, SCADA systems, or external devices like sensors and actuators.

  • Some communication modules support wireless communication protocols like Wi-Fi or Bluetooth.

  • Examples of communication mod...read more

Q8. What is the test done in sites

Ans.

Various tests are conducted on sites to ensure electrical systems are functioning properly.

  • Insulation resistance test to check for any insulation breakdown

  • Earth resistance test to ensure proper grounding

  • Polarity test to verify correct wiring connections

  • Continuity test to check for any breaks in the circuit

  • Load testing to assess the performance of the electrical system

Q9. rating of transformer and about cb

Ans.

Transformer rating is determined by its kVA capacity, while CB refers to circuit breaker used for protection.

  • Transformer rating is specified in kVA, which indicates its capacity to handle load.

  • Circuit breakers (CB) are used to protect electrical circuits from overloads and short circuits.

  • Transformer rating and CB selection are crucial for ensuring safety and efficiency of electrical systems.

  • For example, a 500 kVA transformer may be protected by a 400A circuit breaker.

Q10. Principle of working of motor

Ans.

Motor works on the principle of electromagnetic induction, where a current-carrying conductor experiences a force in a magnetic field.

  • Electric current is passed through a coil of wire, creating a magnetic field.

  • This magnetic field interacts with the magnetic field of the motor's permanent magnets, causing a force on the coil.

  • The force causes the coil to rotate, which is then used to drive mechanical loads.

  • The direction of rotation can be controlled by changing the direction o...read more
