This system is designed to operate 11 kV / 22 kV/33 kV H.T.  Electric supply for H.T.
Consumers.  This is basically for taking  H.T.  Supply for the new establishments or for
converting OH / H.T.  Sub-station of existing establishments. 

1.	This arrangement is simple and safe arrangement for making and breaking of H.T. Supply.   H.T. Consumers with H.T. Metering arrangements with necessary protection  fuses.
2.	Due to availability of very good insulating materials, the clearances can be minimized.   Due to the canopy provided, birding is totally eliminated.  Clearances are as per I.E.   Rules applicable for air insulation, indoor switchgear.
3.	Earlier porcelain insulators along with  alkathine pipe for conductor insulation was used.  Due to epoxy insulators and Raychem insulation the size of total switchgear has been  reduced.

(Specification)
The invention relates to setting up of new arrangement for power supply system, for  11 kV, 22 kV, & 33 kV power supply system. 

In the conventional set up 11/22/33 kV Power supply system made with 4 Pole structure arrangement.  In this 4 pole structure arrangement, various problems like heavy erection work, requirement of more space, more faults percentage during rainy season due to outdoor system.  The drawings are enclosed to have ready reference.

NEW  SYSTEM

In case of Kiosk, H.T. Cable is required for Kiosk as incoming and outgoing.  The conventional power supply system is exposed to atmosphere causing problems due to bird faults etc.  and it is also unsafe and uncomfortable to rectify the faults especially during heavy downpour.

The object of the invention is to devise a system for obviating the above mentioned problems, and to make the power supply system more safe and to give an aesthetically better outlook.  The necessary drawings are enclosed for ready reference.

It is also the object of the invention to reduce space requirement (applicable mainly in urban areas) and to eliminate the hurdle due to installation of the system in the front portion of the establishment.  With this invention, it is easy to have a system which is very simple in construction, easy for operation and also available at affordable price with better aesthetics.

Thus, according to this invention, the power supply system shall be housed in pre-fabricated FRP  Fibre glass / sheet metal casing of size 2.5 mtr X 2.5 mtr with partition for metering room, with underground cabling using GI structure. Copper Bus bars and terminals encased with Raychem sleeves shall be used and a clearance is kept as per IE Rules.  Against the double stack insulators used in the existing system, single stack insulators shall be used in this new system as birding is not there.

In this new system Gang Operating Devices (G.O.D.) operation is with gear boxes duly packed with grease, thus ensuring trouble-free operation.  Besides the above, the new system also provides lockable doors for operation and maintenance.

The level of insulation is maintained during all seasons by providing thermostat space heaters, and moisture formation is avoided.  The cabin is Rodent Vermin proof construction.

In this system supply company metering arrangement is made just below the CT / PT unit behind the see through lockable glass window.  Due to this, tampering with metering system is not possible and revenue will not be affected since primary and secondary of CT / PT are totally enclosed.  Hence, proper billing can be achieved and stealing of electricity is totally prevented.

Over and above without using CT / PT unit & meter, the balance portion of the Kiosk can be used for replacement of 4-pole structure of 2-pole structures which are used by supply companies on roadside.  These arrangements shall avoid the hazards such as falling of structures due to severe weather conditions or accidental falling of maintenance staff from heights, preventing excess expenditure involved therein.
