SLD stands for Single Line Diagram. It is a graphical representation of an electrical system.

• SLD shows the flow of electrical power in a system

• It includes all the components of the system like transformers, generators, breakers, etc.

• SLD helps in identifying faults and troubleshooting

• It is designed using standard symbols and conventions

• SLD is used in power system planning, design, and maintenance

Load can be calculated by determining the amount of power consumed by a device or system.

• Calculate the power consumption of the device or system

• Determine the voltage and current of the load

• Use the formula P = VI to calculate the load

• Consider the power factor of the load

• Use a wattmeter or multimeter to measure the load

Loss in electrical refers to the amount of energy lost during transmission and distribution of electricity.

• Loss in electrical systems can occur due to resistance in wires and transformers.

• This loss is commonly referred to as 'line loss' or 'transmission loss'.

• It is typically measured as a percentage of the total energy transmitted.

• Efforts are made to minimize loss through the use of efficient equipment and better transmission methods.

• Loss in electrical systems can also occur ...read more

Power generation involves converting energy sources into electricity, which is then distributed through a network of power lines.

• Power generation can come from various sources such as coal, natural gas, nuclear, hydro, wind, and solar.

• The electricity generated is then transmitted through high-voltage power lines to substations.

• At the substations, the voltage is reduced and the electricity is distributed to homes and businesses through a network of power lines.

• Distribution sys...read more

Power can be calculated by multiplying voltage and current.

• Power (P) = Voltage (V) x Current (I)

• Unit of power is watt (W)

• Power can also be calculated by dividing work done by time taken

• P = W/t

Resistance is the opposition to the flow of electric current, while impedance is the total opposition to the flow of alternating current.

• Resistance is measured in ohms and is caused by the physical properties of a material.

• Impedance is measured in ohms as well, but it takes into account both resistance and reactance.

• Reactance is the opposition to the flow of alternating current caused by capacitance or inductance.

• Impedance can be calculated using the formula Z = R + jX, where...read more

UPS provides backup power to prevent data loss and equipment damage during power outages.

• Prevents data loss and equipment damage during power outages

• Provides backup power to critical systems

• Ensures uninterrupted power supply

• Protects against power surges and spikes

• Ideal for businesses with mission-critical operations

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is a fundamental law of electrical engineering.

• It relates the three basic electrical quantities: voltage, current, and resistance.

• The formula for Ohm's law is V = IR, where V is voltage, I is current, and R is resistance.

• Ohm's law is used to calculate the behavior of electric circuits and is essential for designing and troubleshootin...read more

The colour code of resistance is a system used to identify the resistance value of electronic components.

• The code consists of four or five coloured bands on the component.

• The first two bands represent the significant digits of the resistance value.

• The third band represents the multiplier or number of zeros to be added to the significant digits.

• The fourth band represents the tolerance or the percentage deviation from the stated resistance value.

• The fifth band, if present, repr...read more
