Dtr & PSS structure of SLD refers to Distribution Transformer and Package Substation structure in Single Line Diagram.

• Dtr stands for Distribution Transformer which is used to step down voltage for distribution purposes.

• PSS stands for Package Substation which is a compact unit containing transformers, switchgear, and control equipment.

• In a Single Line Diagram (SLD), Dtr and PSS are represented by symbols to show their l...read more

PTR stands for Project Technical Report.

• PTR is a document that summarizes the technical aspects of a project.

• It includes details such as project scope, objectives, methodology, results, and conclusions.

• PTRs are often used to communicate project progress and findings to stakeholders.

LT pole election rule refers to the guidelines and regulations for selecting and installing low tension electrical poles.

• LT pole election rule specifies the criteria for selecting the appropriate location for installing low tension electrical poles.

• It includes factors such as distance from buildings, roadways, and other structures, as well as soil conditions and accessibility.

• Compliance with LT pole election rule ensur...read more

Coil earthing is a method of grounding electrical systems to prevent electric shock and ensure safety.

• Coil earthing involves burying a coil of wire in the ground to create a low-resistance path for electrical currents to flow safely.

• The depth at which the coil should be buried depends on factors such as soil type, moisture content, and local regulations.

• Proper installation of coil earthing is essential to protect equip...read more

Bituminous laying temperature is 130-150°C and rolling temperature is 80-100°C.

• Bituminous laying requires higher temperature than rolling.

• Temperature range ensures proper compaction and adhesion.

• Temperature can vary based on the type of bitumen and aggregate used.

• Proper temperature control is crucial for quality bituminous pavement.

• MDD & MCC should be as per

The design procedure for DLC mix includes using M15 grade concrete, minimum cement content of 150 kg/cum, and achieving a compressive strength of at least 10 MPA after 7 days of curing.

• Use M15 grade concrete with aggregate and cement ratio of 12:1

• Minimum cement content of 150 kg/cum, or 120 kg/cum if fly ash content is over 20%

• Achieve a compressive strength of at least 10 MPA after 7 days of curing

• DLC mix should be hom...read more

The question is about the suitability of aggregate size and water absorption for PQC with a total thickness of 300mm and tolerance of +/-6mm.

• Aggregate size of 31.5mm is suitable for PQC with a total thickness of 300mm and tolerance of +/-6mm.

• Water absorption to GSB DLC being the same for PQC is also suitable.

• The suitability of the material is important for the successful completion of the project.

The design procedure for cement concrete includes minimum cement content, strength requirements, dowel bar and tie bar specifications, and surface preparation and curing techniques.

• Minimum cement content of 360 kg/cum if fly ash is more than 20%, and 310 kg/cum otherwise

• Flexural strength of cement concrete after 28-day curing should be 4.5 MPa, and compressive strength should be 40 MPa

• Dowel bar size of 32mm dia and 300...read more
