  • Fire-Fighting Precautions in Power Substation

    Introduction to Fire ProtectionFire Safety Considerations in SubstationsDesign For Effective Fire ProtectionThe layout of the plant and the design of the building play a major part in reducing the spread of fireand the effect of explosions. For example, equipment and buildings should be arranged to have vents which rupture rather than allowing an explosion to damage the main fabric.Site supervisors should ensure that these vents are never obstructed. In the prevention of fire, cleanliness and tidiness are very important, as is the careful maintenance of tools. The choice of fire-fighting equipment is dependent on its suitability for electrical fires but also on cost and the importance of the electrical supplies at the point in question. Portable manual types are as follows: halon gas of various kinds, carbon dioxide chemical foam and powder. Fixed systems use water sprinklers, carbon dioxide and halon gas. Both halon gas and carbon dioxide can suffocate personnel trapped in the discharge area. Strict precautions must therefore be taken to lock-off the equipment when staff are present. The...

The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.

  • Gas tungsten arc welding - Wikipedia

    Gas tungsten arc welding, also known as tungsten inert gas welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas. A filler metal is normally used, though some welds, known as autogenous welds, or fusion welds do not require it. When helium is used, this is known as heliarc welding.
