3PH supply is a three-phase electrical power supply with 415V voltage, while single-phase supply is a single-phase electrical power supply with 230V voltage.

• 3PH supply has three alternating currents that are out of phase with each other, while single-phase supply has only one alternating current.

• 3PH supply is commonly used in industrial and commercial applications, while single-phase supply is used in residential and small commercial applications.

• Examples of 3PH supply applic...read more

An 11kv substation typically consists of transformers, circuit breakers, isolators, lightning arresters, busbars, and control panels.

• Transformers: Step up or step down voltage for distribution.

• Circuit breakers: Protect the system from overloads and short circuits.

• Isolators: Provide isolation for maintenance work.

• Lightning arresters: Protect equipment from lightning strikes.

• Busbars: Distribute power within the substation.

• Control panels: Monitor and control the substation opera...read more

The question involves calculating unit changes in different modes and finding the volume of a given figure.

• Identify the different modes in which the units are changing

• Convert the units to a common measurement system if necessary

• Calculate the volume of the given figure using appropriate formulas

Rate analysis involves calculating the rates of various items in a construction project to determine the overall cost.

• Gather detailed information on the quantities and specifications of materials, labor, and equipment required for the project.

• Determine the unit rates for each item by considering factors such as market prices, labor costs, and equipment rental rates.

• Calculate the total cost of each item by multiplying the quantity required by the unit rate.

• Sum up the total cos...read more

Single phase supply is a type of electrical power distribution that uses a single alternating current (AC) waveform.

• Single phase supply has only one voltage waveform that alternates in a sinusoidal manner.

• It is commonly used in residential and small commercial applications.

• The voltage of a single phase supply is typically 230V in Europe and 120V in North America.

• Single phase supply is not suitable for high power applications and three phase supply is used instead.

A tender is a formal offer or proposal made by a company in response to an invitation to bid for a project or contract.

• Tenders are used in the procurement process to select the best supplier or contractor for a project.

• They typically include details such as pricing, timelines, and specifications.

• Tenders are usually submitted in response to a Request for Proposal (RFP) or Invitation to Tender (ITT).

Earth potential rise is the increase in voltage that occurs when a large current flows into the ground.

• Occurs when a large current is injected into the ground

• Can be caused by lightning strikes, fault currents, or power system faults

• Can lead to dangerous touch and step potentials

• Important to consider in grounding and lightning protection systems

Kirchhoff's Law states that the total current entering a junction is equal to the total current leaving the junction.

• Kirchhoff's Current Law (KCL) states that the algebraic sum of currents entering a node is zero.

• Kirchhoff's Voltage Law (KVL) states that the sum of voltage drops in a closed loop is equal to the applied voltage.

• These laws are fundamental in analyzing electrical circuits and are used to solve circuit problems.

• KCL and KVL are essential for determining unknown cu...read more
