It is the simply the conversion of energy from one form to another.

Generation

in this type of generation the machine are high speed but slow starting.

Fossil

The used of this is to protect the transmission system and to ensure reliable operation. These include ground wires, lightening arrestors, circuit breakers, relays etc.

Protective devices

this is used to mechanically support the line conductors while electrically isolating them from the support towers.

Line insulators

after being produced at generating stations is transmitted to the consumers for utilization.

Electrical energy

are used to keep the voltage within permissible limits at the receiving end.

Voltage regulators

are slow machines but they are quick starting and have a good ramping rate.

Hydral Machine

consists of a network of overhead lines and underground cable.

Transmission system

overhead AC lines are applied on power system as voltages in this range.

115 KV to 800 KV

must of proper size (i.e, cross-sectional area). This depends upon its current capacity.

Conductors

an electrical generating power stations, electrical power is generated at __________ level that ranges from 11KV to 25KV.

medium voltage level

Nowadays electrical energy is generated, transmitted and distributed in this form.

classification of transmission lines referred to voltage will range from 745 KV to 999 KV.

Extra High Voltage

one of the main disadvantages of AC or HVAC transmission is a continuous power loss due to _______ because of line capacitance.

Charging current

classification of transmission lines referred to distance with length less than 50 KM.

Short length

acts as shield to protect the energized conductors from lightning strokes.

Ground wire

what does ACSR stand for?

Aluminum Core Steel Reinforced

DC lines are sometimes called in this term since they can be used to interconnect two systems operating at different frequencies.

Asynchronous ties

are used in very densely populated areas but they are rarely used because they are more expensive as they require insulating materials instead of air in separate conductors from each other and from ground.

Underground cables

the phenomenon of violet glow, hissing sound, and production of ozone gases in an overload transmission line. in electricity, the tendency of alternating high- frequency currents to crowd toward the surface of a conducting materials. This Phenomenon restricts the current to a small part of the total cross-sectional area and so has the effect of increasing the resistance of the conductor.

Corona Effect in Overhead Transmission Line

the vertical difference in level between the conductor support points and the lowest point of the conductor. Overhead conductors are used to transmission of power from the power station to the distribution end as well as from the distribution ends to consumers.

Sag

this consists of a network overhead lines and underground cables by which the power is distributed to the ultimate users of electricity that is the load.

Distribution system

Main Elements of Transmission lines:

- Conductors - Transformers - Line insulators - Support towers - Protective Devices - Voltages Regulators

used for stepping up and down the voltage level of power

Step up & Step down transformer

used in three phase power system

Three Phase Transformer & Single Phase Transformer

transferring energy between high voltage and very high voltage system

Power Transformer

designed for installing at indoor and outdoor.

Indoor Transformer & Outdoor Transformer

cooling medium

Oil cooled transformer

used as the cooling medium instead of oil.

dry type Transformer

device controlling the power flow

Phase Shifting Transformer

is an electrical device used to transform current as well as voltage level.

Instrument transformers

transformer with only one winding.

Autotransformers

to regulate the output voltage of a transformer.

Transformers Taps

allows to select the ratio change

On load tap changer

mechanisms require the transformer to be isolated.

Off load tap changing
