•Repairs and fabricates, as necessary any mechanical parts. Carried out cutting and above-mentioned jobs.
•Complies with safety conditions and practice on all equipments on which he is working and observes the work permit regulations.
•Knowledge in motor overhauling, like dismantling bearing removal & testing, replacing, inspection windings and assembling.
•Follow test procedure for relay testing like over load relay earth fault relay, under voltage relay, and prepare test reports.
Maintenance of Motor:
When on electric motor has been properly installed it requires little attention later on to keep it working properly. If the motor is kept clean and dry and properly lubricated it will give trouble free service for a long time.
The following are the maintenance works to be carried out in a motor.
•Check all high speed bearings and renew if necessary
•Blow out all motor windings thoroughly with clean dry air
•Overhaul motors which has been subjected to severe operating conditions
•Check insulations resistance to earth between phases of motor windings, control gear and wiring
•Clean and Varnish dirty and oily windings
•Renew switch and fuse contacts if necessary
•Check the resistance of earth connections
•Check the air gap and ensure that the rotor does not rub against the stator core
•Ensure that the ball or roller bearings have adequate lubricating grease
Maintenance of Transformer:
Mostly troubles in distribution transformer will occur in the HV winding, because it is made up of very thin conductor of large number of turns and the voltage is also high. The fault may be either a short circuit between HV turns or a cut in the HV winding. To find out the troubles in the HV winding continuity or short circuit tests are carried out
The following electrical tests are normally carried in the transformer
•Using transformer oil tester the BDV of the oil should be tested
•Acidity Test should be conducted
•Insulation resistance of winding must be ascertained
•Transformer is dried out to improve the IR value
Turbo Generators:
•Check electrolyte level in batteries top up it needs
•Lube oil analysis
•Check all lube oils & fuel filters
•Check operating temperature
•Check all auxiliaries
•Cleaning of all air filters
•Drain the accumulated oil from the sand trap
•Check operating temperature and load
•Vibration trending of alternator DE/NDE bearing
•Compressor blade cleaning by Jet blast
Emergency Generator:
•Test run & check all parameters
•Check batteries
•Check all priming system
Multi Channel Fire Protected System.
Description:
This project is very cheap and user friendly. It can be implemented in any place. It consumes very less power for its operation. Since microcontroller is used the operations are very accurate
