• Electricity consumption is measured in kilowatt-hours (kWh)

• The rate per unit is determined by the electricity provider

• Additional charges may include taxes, surcharges, and service fees

• Discounts may be applied for prompt payment or energy-saving practices

An energy meter is connected by wiring it to the electrical circuit of a building or facility.

• An energy meter is typically connected to the main electrical panel of a building.

• The meter is wired in series with the main power supply to measure the amount of electricity consumed.

• The connection must be done by a qualified electrician to ensure safety and accuracy.

AT&C losses refer to Aggregate Technical and Commercial losses in the electricity distribution system.

• AT&C losses include technical losses (due to resistance in wires, transformers, etc.) and commercial losses (due to theft, billing errors, etc.)

• These losses are expressed as a percentage of the total energy input into the distribution system.

• Reducing AT&C losses is crucial for improving the financial health of distribution companies and ensuring reliable power supply to consu...read more

Copper loss refers to the power loss in an electrical machine due to the resistance of copper windings.

• Copper loss is also known as I^2R loss, where I is the current flowing through the winding and R is the resistance of the winding.

• It is a major factor in determining the efficiency of electrical machines.

• Copper loss can be reduced by using materials with lower resistance or by increasing the size of the conductors.

• For example, in a transformer, copper loss occurs in the prim...read more
