Integro Finserv Interview Questions and Answers

There are various types of welding such as MIG, TIG, Stick, and Flux-Cored. MIG welding is a popular type of welding.

• MIG welding uses a wire electrode and a shielding gas to join two metal pieces together.

• TIG welding uses a tungsten electrode and a filler metal to create a weld.

• Stick welding uses a consumable electrode coated in flux to create a weld.

• Flux-Cored welding uses a wire electrode with a flux core to create a weld.

• MIG welding is commonly used in automotive and manuf...read more

Corona effect in transmission lines is the phenomenon of ionization of air surrounding the conductors due to high voltage, leading to energy loss and audible noise.

• Corona effect occurs when the electric field strength around the conductor exceeds the breakdown strength of air, causing ionization of air molecules.

• This ionization results in loss of energy in the form of light, heat, and sound, leading to power loss and audible noise in the transmission line.

• Corona effect can be...read more

Latent heat is the heat absorbed or released by a substance during a phase change without a change in temperature.

• Latent heat is the energy required to change the state of a substance without changing its temperature.

• It is the heat absorbed or released during a phase change.

• Latent heat is important in processes such as melting, freezing, vaporization, and condensation.

• Examples include the heat absorbed by ice to melt into water and the heat released by water vapor to condense...read more

3 phase motors operate on the principle of electromagnetic induction to generate rotating magnetic fields.

• Three phase motors have three sets of windings spaced 120 degrees apart

• When current flows through the windings, it creates a rotating magnetic field

• The rotating magnetic field interacts with the rotor to produce motion

• Common types include induction motors and synchronous motors

Transmission lines are used to transmit electrical energy from one point to another efficiently.

• Transmission lines are used to carry electrical signals or power from a source to a load.

• They are designed to minimize losses and maintain signal integrity.

• Single line diagram represents the transmission line as a single line with symbols for components like transformers, circuit breakers, etc.

• Examples of transmission lines include overhead power lines and underground cables.

A thermal power plant diagram shows the process of generating electricity using heat energy.

• The diagram typically includes components such as boilers, turbines, generators, condensers, and cooling towers.

• Heat energy from burning fossil fuels or nuclear reactions is used to produce steam, which drives turbines to generate electricity.

• The steam is then condensed back into water and recycled in the system.

• Cooling towers are used to dissipate excess heat from the process.

• Example:...read more
