pad mounted transformer

Pad mounted transformer can be overhead or ground pad mounted it depeneds
upon the customer request. You need pad mounted if your proposed transformer
above 3-100 kva. for pole mounted only below 3-100 kva but for 100 kva must
be installed in a 40 feet 350 kgms concrete pole and it must be located at
customer compound for safety purposes.

Substation convert from 138 kv to 69 kv

A 50 MVA power transformer to transform 138 kv to 69 kv supplying 5 69 kva substation.

Transformer Classification

This articles involves about the classification of the transfomer, before we go along let us define first transformer. Transformer is a static device for transforming electrical energy from one alternating current circuit to another without any change in frequency. It changes voltage from high to low and low to high with a corresponding increase or in decrease current. If the voltage increased it is said to be stepped up. If it is decreased, then it is said as stepped down. List below are the classification of transformer.

TRANSFORMER CLASSIFICATION

• According to SIZE
1. DISTRIBUTION TRANSFORMER – Used from transferring power from a primary distribution circuit to a secondary distribution circuit according to SIZE
2. POWER TRANSFORMER – Are used for transferring power from any part of the system between the generator down to the primary distribution system according to SIZE

• According to INSULATION
1. LIQUID- IMMERSED TRANSFORMERS – Are those whose core and coils are immersed in an insulating liquid.
– Liquid can either be mineral or synthetic.
– Liquid should be non-flammable
2. DRY TYPE TRANSFORMERS – Whose core and coils are gaseous or dry compound insulating medium.
– Usually LV and MV systems

• According to LOCATION
1. INDOOR TRANSFORMERS – Is one which because of construction much be protected from weather.
– Usually dry type or non flammable oil immersed type.
2. OUTDOOR TRANSFORMERS – Is of weather resistant construction suitable for service without the additional protection from weather.
– Usually of the mineral oil immersed type.
3. STATION TYPE TRANSFORMERS – Are those designated for installation in a power station or substation.
– Usually at voltages above 34.5kV in any of the windings.
4. UNIT SUBSTATION TRANSFORMER – Is one which is mechanically and electrically and coordinated in the design with, one or more switchgear or motor
control assemblies or combination thereof.
5. CLASSIFICATIONS OF UNIT SUBSTATION TRANSFORMER
1. PRIMARY UNIT SUBSTATION – One with voltage section above 1000V
2. SECONDARY UNIT SUBSTATION – One with voltage section below 1000V.
6. NETWORK TRANSFORMERS – Is designed for use in a vault to feed a variable capacity system in interconnected secondaries

7. PAD MOUNTED TRANSFORMER – Is an outdoor type used as part of an underground distribution system.
– They are mounted on a foundation pad.
8. POLE-TYPE TRANSFORMER – Is one which is suitable for mounting on a pole or similar structure.
9. VAULT TYPE TRANSFORMER – Is constructed so as suitable for occasional submerged operation in water under specified conditions
of time and external pressure

Comparison of alternating current and direct current in transmission lines

I wonder why most of the transmission lines are used ALTERNATING CURRENT not
DIRECT CURRENT. List below are the following reasons.

Advantages of direct current transmission lines
The advantage of DC transmission lines are only two conductors to be used
and there is no problem of system instability, in a DC line has less corona loss
and reduced interference with communitation circuits, since the same value of
voltage therefore the insulating materials on DC lines experience less
stress compared to AC transmission lines, in a DC transmission lines also no skin
effect on conductors, therefore the entire cross-section of conductor is
usually utilized thereby affecting saving in materials. also same load and
sending end voltage, and voltage drop in DC is less than AC transmission lines and
you no problem of inductance, capacitance and phase displacement which is common
in AC transmission lines.

Disadvantages of direct current transmission lines
The disadvantage of DC you cannot anymore step-up or
step down you voltages in equipment like transformer.
And the generation of power at high DC voltages is difficult due
to communication problems and cannot be usefully utilised at consumer load.

Advantages of alternating current transmission lines
On AC transmission lines has less power losses in high voltage and
there is no commutation problem. possible for step up or step down
voltage.The power can be generated to a high voltage.

Disadvantage of alternating current transmission lines
There is increased of effective resistance due to skin effect and more copper
is required. The construction of AC transmission lines in very much
complicated and costly. There is problems of inductances and capacitances because
it exist in transmission lines.
