RTI Act 2005: A very powerful and useful act to the citizens of India.

A citizen has a right to seek such information from a public authority which is held by the public authority or which is held under its control. This right includes inspection of work, documents and records; taking notes, extracts or certified copies of documents or records; and taking certified samples of material held by the public authority or held under the control of the public authority.

While submitting information under this act the Public Information Officer feels uncertain at times.

How current flows at light speed when electrons move at snails speed? (Back to basics)

Tags

, ,

When you first learned about electric currents, you may have asked how the electrons in a solid material move from the negative to the positive terminal. In principle, they could move ballistically or ‘fly’ through the solid, without being affected by the atoms or other charges of the material.

But, this actually never happens under normal conditions because the electrons interact with the vibrating atoms or with impurities and collide with them. These collisions in a solid typically occur within an extremely short time, usually about 100 femto seconds (tenth of a trillionth of a second). So the electron motion along the material, rather than being like running down an empty street, is more like trying to walk through a very dense crowd.

How Reorder Point Technique Ensures Availability of Stock at Stores?

Our Company spends on an average of 1100 Crores per year for various capital works and maintenance works. Majority of these works requires different types of major and minor materials. Availability of the right material in required quantity at the right time is very much crucial. Non-availability of the materials not only delays planned works but also over burdens the existing network. On flip side, unplanned spending of such huge amounts directly impacts Company’s finances. Hence, proper material procurement planning is very much essential.

There are many techniques on which material procurement decisions can be taken. One such technique is consumption based procurement planning – where procurement decision of a material is taken based on its consumption history.

HVDS Project – Features and Advantages

Tags

, , , , ,

HVDS is acronym for High Voltage Distribution System. This system is being implemented exclusively for giving supply to agriculture connections on selected 11KV agriculture feeders. Implementation of HVDS involves conversion of Low Voltage Distribution System to High Voltage Distribution System – HVDS by replacing the existing 415V LT line to 11KV HT line and replacing the higher capacity (100/63KVA) Distribution Transformers (also known as “mother DTR”) with lower capacity (25KVA) Distribution Transformers.

In HVDS system, LT overhead line is completely avoided and instead LT AB cable is used from DTR up to consumer agriculture bore well, thus eliminating LT line faults 100%.

Additional Annunciation System for 33/11KV Substations

, ,

This is an article on technical subject pertaining to 33/11KV substations.  In APCPDCL most of the substations are designed for two power transformers, two 33KV incoming sources (one regular and one alternate supply) and will be feeding six to eight 11KV feeders.  Generally, substations will be fed from one source.  In this condition all the feeders, station transformer, potential transformer, auxiliary equipment are fed from one source.  But when the substation is fed from two different 33 KV sources at a time due to some technical reasons, then one power transformer will be fed from one source and other power transformer will be fed from other source.  This is done by opening the bus coupler on 33KV bus and 11KV bus.  On separation of 11KV bus, the station transformer will be on one side of the bus only.  The station transformer will be feeding auxiliaries, substation lighting, fans etc and substation lighting and fans will indicate presence of incoming supply most of the cases.  When the 33KV source feeding the station transformer via power transformer fails, the operator knows it by observing the condition (off status) of fans and lights in the control room and takes action required.
