A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV Transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.
What else can I help you with?
What do you mean by package substation?
Prefabricated power distribution substation Its basically a whole 11kv substation but in one unit. It contains a transformer, ring main unit, fuse board and circuit breakers etc. It still uses as much space as a normal substation that houses a separate transformer, ring main unit etc but is easier to transport and is probably cheaper.
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
Why you are indicating capacity of transformer in KVA?
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
What is a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
Components used to build the substation?
Substation main components include the following:1. The power transformer which is the heart of the Substation. It is the Power transformer that steps up (in the case of a step up Substation for transmission) or steps down (in the case of step down Substation for distribution) the voltage e.g. 132/33kV (step down), 33/132kV (step up).2. The Auxiliary transformer (which is fed from the output of the Power Transformer). This transformer powers the substation accessories and auxiliary equipments such as controls, lighting, Substation control room etc)3. Disconnecting switch or Isolators4. Earthing switch for grounding the main line in case there is need for maintenance work5. Control relays and Protective relays for short circuit, over voltages etc6. Instrument transformers e.g. voltage transformers, current transformers that will take current from the main high voltage line in case of an over current on the line and produce a current that the protective relays can operate with.7. Supervisory Control and Data Acquisition (SCADA) systems for line monitoring and control8. DC power supply system in the form of batteries for supplying DC loads such as emergency lightings, relays, rectifiers, chargers etc.9. Lightning arrestors10. Surge arrestors11. Switchgears for the high and low voltage levels, AC/DC panels12. Circuit breakers for the high and low voltage levels
Can a a electric substation in a city use transformers to increase the power output?
No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.

What is 132kva gridstation?
132 Kilo Volt Amps (kVA) is the amount of theoretical power being used by the transformer. The transformer takes high voltage from transmission lines and converts it to lower usable voltages. the power of 132 kVA comes from the product of current (I) and voltage (V) going into or coming out of the transformer. The gridstation as a whole takes in a few large power transmission lines, transforms their voltage, and distributes electricity to consumers.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What is the maximum value power capacity of dry type transformer?
What's the maximum value power capacity of dry type
What is the meaning of diameter in power substation diameter refers to transformer bay or transmission line bay in a substation?
A arrangement of Equipment between two bus-bars. Example 1 and 1/3, 1 and half etc.
What is the maximum capacity of power transformer at 220kV voltage?
800 MVA

When 2 power transformers are operated in parallel what would be the net capacity Is it less than the total capacity of above transformer?
iT is above Transformer because The Two power Transformers are operaTed iT for The same shape buT cuT in half
