ppt of earth leakage circuit breaker

An Earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use residual current circuit breakers which instead detect leakage current directly. ....etc

Brackets for rails

Any device used to secure rails on chairs or base plates or directly to sleepers, brackets or other rail supports. The rail fastening keeps the rails fastened to the sleepers (transfer of forces), provides adequate slope of the rail foot (1:20, 1:40) in the transverse plane, prevents the rail from moving longitudinally, dampens the noise And vibrations from the rails.
General requirements for rail fasteners
Rail fasteners shall:
1. Hold the rails firmly on the rail seat.
2. limit the rotation of the rail around ....etc

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent or overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear de ....etc

This project is aimed to identify the criminals in any investigation department. Here the technique is we already store some images
of the criminals in our database along with his details and that images are segmented into many slices say eyes, hairs, lips, nose, etc.
These images are again stored in another database record so to identify any criminals; eyewitnesses will see the images or slices that
appear on the screen by using it we develop the face, which may or may not be matched with our images. If any image is matched
up to 99% then ....etc
