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 pocket substation?
the pocket substation have three major parts and they are transformer , ring main unit (RMU) and low voltage distribution bored (LVDB).
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
What is MDB and SMDB in electrical?
MDB= Main Distribution Board, it is usually fed from a substation and supplies electricity to a Sub Main Distribution Board ( SMDB ) The SMDB goes on to supply electricity for a panel

What is auxiliary memory give an example of auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing. Some examples of auxiliary memory would be disks, external hard drives, USB drives, etc.
