ABSTRUCT
During this complete training, I got well versed with various electrical devices and circuits. Besides this, I did a deep study about the various methods of theft of electricity and also the techniques used to control such theft, the various latest trends in technology used for energy meters to get an accurate energy measurement.
Once the Energy meters were deeply studied, I gained knowledge about various other products manufactured by the company like MCB’s, Mono block Pumps, Ceiling Fans and Motor Starters etc.
In ceiling fan department I comes to know about the different types and rating of fans under manufacturing. Then we had done practically work there.
In MCB department we comes to know about the methods of adjusting the operating time of MCBs, testing of MCBs.
All in all this training has been really beneficial for me in gaining vital practical knowledge about various devices and circuits in the field of Electrical and Electronics.
COMPANY PROFILE
BENTEX started 50years back at Delhi with manufacturing of electrical items like AC ENERGY METERS ,M.C.B, CEILING FANS etc.
Later on Chopra Brother’s Mr. Satish Chopra, Mr. Kapil Chopra & Mr. Nishit Chopra has promoted the group and it is so named SKN-BENTEX GROUP.
The Group have been certified for ISO-9001 and products are also ISI MARKED& BSI REGISTERED.
Besides manufacturing with various electrical item now the company is engaged infield of LPG REGULATORS ,BUILDING CONSTRUCTION and EXPORT ACTIVITIES.
FUTURE ENERGY METERS
AMR [Automatic Meter Reading] and RMR [Remote Meter Reading] describe various systems that allow meters to be checked without the need to send a meter reader out.
An electronic meter can transmit its readings by telephone line or radio to a central billing office.
Automatic meter reading can be done with GSM (Global System for Mobile Communications) modems, one is attached to each meter and the other is placed at the central utility office.
MINIATURE CIRCUIT BREAKER’S
A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Its basic function is to detect a fault condition and then interrupting the continuity of electrical flow until the fault becomes over.
MCB (Miniature Circuit Breaker)—The commonly-available preferred values for the rated current are 5 A, 10 A, 13A, 16A, 20 A, 25 A, 32 A, 40 A, 50 A, 63A, 80 A and 100 A not more than 100A each having different tripping time.
OPERATION
All circuit breakers have common features in their operation, although details vary substantially depending on the voltage class, current rating and type of the circuit breaker.
The circuit breaker must detect a fault condition; in low-voltage circuit breakers this is usually done within the breaker enclosure. Circuit breakers for large currents or high voltages are usually arranged with pilot devices to sense a fault current and to operate the trip opening mechanism. The trip solenoid that releases the latch is usually energized by a separate battery, although some high-voltage circuit breakers are self-contained with current transformers, protection relays, and an internal control power source.
Once a fault is detected, contacts within the circuit breaker must open to interrupt the circuit; some mechanically-stored energy (using something such as springs or compressed air) contained within the breaker is used to separate the contacts, although some of the energy required may be obtained from the fault current itself. Small circuit breakers may be manually operated; larger units have solenoids to trip the mechanism, and electric motors to restore energy to the springs.
HISTORY
The first ceiling fans appeared in the 1860s and 1870s, in the United States. At that time, they were not powered by any form of electric motor. Instead, a stream of running water was used, in conjunction with a turbine, to drive a system of belts which would turn the blades of two-blade fan units. The electrically-powered ceiling fan was invented in 1882 by Philip Diehl. By World War I, most ceiling fans were being manufactured with four blades instead of the original two. Besides making fans quieter, this change allowed them to circulate more air, thereby making more efficient use of their motors.
