10+ AppInventiv Technologies Interview Questions and Answers

Transformer oil is typically mineral oil, and efficient transformers are usually dry-type transformers.

• Transformer oil is usually mineral oil, which acts as a coolant and insulator in transformers.

• Efficient transformers are often dry-type transformers, which do not require oil for cooling.

• Other types of transformer oils include silicone-based oils and bio-based oils.

• Efficient transformers may also include amorphous core transformers or superconducting transformers.

SLD (Single Line Diagram) shows the electrical connections from substation to room light.

• Start with the substation as the power source

• Draw a line representing the main distribution line

• Include transformers, panels, switches, and cables

• End with the room light as the final destination

SP stands for Schedule Performance, TPN stands for Total Planned Value, VTPN stands for Value of Total Planned Value

• SP is a measure of how well the project is adhering to the schedule

• TPN is the total budgeted cost of the work scheduled to be done

• VTPN is the earned value of the work actually completed

Distribution boxes are used to distribute electrical power to different circuits or devices within a building.

• Distribution boxes can be categorized based on the number of ways or circuits they can accommodate (e.g. 4-way, 8-way, 12-way)

• They can also be classified based on the type of protection they offer (e.g. MCB distribution box, RCCB distribution box)

• Distribution boxes can be surface-mounted or flush-mounted depending on the installation requirements

The type of wire flexible depends on the material used and the intended application.

• Different types of flexible wires include silicone wire, PVC wire, and Teflon wire.

• The flexibility of a wire can be determined by its strand count and gauge.

• Flexible wires are commonly used in industries like electronics, automotive, and robotics.

Copper is the most commonly used material in wire due to its high conductivity and affordability.

• Copper is the most common material used in wire due to its high conductivity and affordability

• Other materials used in wire include aluminum, silver, and gold

• The choice of material depends on the specific application and requirements

Copper wiring typically uses copper with high conductivity, such as copper with a purity of 99.9% or higher.

• Copper wiring commonly uses high-conductivity copper, such as ETP (Electrolytic Tough Pitch) copper.

• Copper wiring may also use OFHC (Oxygen-Free High Conductivity) copper for applications requiring high purity.

• Copper wiring with a purity of 99.9% or higher is often preferred for electrical conductivity.

• Different types of copper wiring may be used based on specific requi...read more

The type of wiring used depends on the specific project requirements and regulations.

• Consider the voltage requirements of the project

• Choose between solid or stranded wire based on flexibility needs

• Select the appropriate wire gauge for the current load

• Follow local electrical codes and regulations

• Examples: THHN wire for general wiring, Cat6 cable for networking projects

Layers of cable refer to the different levels of insulation and protection surrounding the core conductor.

• Layers of cable provide insulation and protection for the core conductor.

• Common layers include conductor, insulation, shielding, and jacket.

• Examples of cables with multiple layers include coaxial cables and Ethernet cables.
