Q1. Are you familiar with the different varieties of wires used in transmission?

Ans.

Yes, there are different types of wires used in transmission.

  • The most common types of wires used in transmission are copper, aluminum, and steel-cored aluminum.

  • Copper wires are the most efficient and expensive, while aluminum wires are less efficient but more affordable.

  • Steel-cored aluminum wires are used for long-distance transmission as they have high tensile strength.

  • Other types of wires used in transmission include ACSR (Aluminum Conductor Steel Reinforced) and AAC (All A...read more

Q2. What are the defferent b/w nutral wire and earth wire

Ans.

The neutral wire carries current back to the source, while the earth wire provides a path for electrical faults to safely discharge.

  • Neutral wire carries current back to the source

  • Earth wire provides a path for electrical faults to safely discharge

  • Neutral wire is typically colored white or gray

  • Earth wire is typically colored green or green with yellow stripes

  • Neutral wire is connected to the grounding system at the main electrical panel

  • Earth wire is connected to the grounding e...read more

Q3. Can you mention a few differences between a fuse and a breaker

Ans.

A fuse is a one-time use device that melts when overloaded while a breaker can be reset and reused.

  • A fuse needs to be replaced after it melts while a breaker can be reset

  • A fuse is cheaper than a breaker

  • A fuse reacts faster to overloads than a breaker

  • A breaker can handle higher current loads than a fuse

  • Examples of fuses include glass tube fuses and cartridge fuses while examples of breakers include thermal-magnetic and ground fault circuit interrupters (GFCI)

Q4. How many types are there in solar panel installation

Ans.

There are mainly two types of solar panel installation: On-grid and Off-grid.

  • On-grid installation is connected to the main power grid and excess energy can be sold back to the utility company.

  • Off-grid installation is not connected to the main power grid and requires battery storage to store excess energy.

  • Other types include ground-mounted, roof-mounted, and pole-mounted installations.

  • Installation methods can also vary depending on the type of roof or ground surface.

Q6. Transformers in two windings primary and secondary

Ans.

Transformers have two windings, primary and secondary, which are used to transfer electrical energy from one circuit to another.

  • Primary winding receives electrical energy from the source

  • Secondary winding transfers the electrical energy to the load

  • The ratio of turns in the primary and secondary windings determines the voltage transformation

  • Transformers can step up or step down voltage levels

  • Examples: power transformers, distribution transformers

Q9. How to use transformer

Ans.

Transformers are used to step up or step down voltage levels in electrical circuits.

  • Transformers consist of primary and secondary coils wound around a core

  • Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels

  • Transformers work on the principle of electromagnetic induction

  • They are used in power distribution systems, electrical appliances, and electronic devices

Q10. Transformers in oile use

Ans.

Transformers in oil are used for insulation and cooling purposes.

  • Oil acts as an insulating medium to prevent electrical breakdown

  • Oil also helps in dissipating heat generated during operation

  • Commonly used oils include mineral oil, silicone oil, and vegetable oil
