Aim:  Learning about tripod stand. Requirements: Tripod stand U-shaped petti Compass olamba Ranging rod Paper Small nails  abilate  petti Procedure : First we go to the plane surface and we putted the tripod stand in one corner. Than we fix table on tripod stand next we take u-shaped petti we put at down ward nut bolts at middle and we measure the midpoint of table and we put a paper and at middle, we marked it by nailing at down ward nut bolts.I put volamba to U-shape petti and we put stone at the straight volumba then we take abilate patti measure it at the corner we put ranging rod straightly and we measure it like this and we take the measure rement of that. Formula :1cm=10cm                10cm=100cm               1mm=10mm then we assembled the line then we see there is no shape then sir told to make triangle in it and we take measure...

Electric load: - Aim: - calculating electric load… Procedure : - while calculating the load the main value in voltage load calculation to total voltage… How know how to count load … 1)                Counting current in whole vigyan ashram 2)                Help of that remove current 3)                By help of current wire gauge is decided… Machine Voltage Current Watt Tube light 230 3.75 3040 Lathe machine 230 8.5 280 Computer 230 0.92 280 Cutter 230 4.3 150 Drill machine 230 02.3 200 Depot welding 230 5.1 220 Arc welding 230 3.1 880  Drill machine 230 0.26 ...

Aim: Information about earthing practically. Requirements: Materials: ·        Copper plate ·        Salt ·        Coal ·        Pipe Tools: ·        Tikka ·        Pravda ·        Par   Procedure: Ø First choose a wet surface. Ø start digging under 2meter in earth. Ø Put some salt in the hole. Ø Connect your copper plate with wire using nut bolt. Ø Put plate in hole. Ø Take the wire inside from pipe. Ø Put it straightly then drop some coal in it. Ø Then put some salt then again coal. Ø After this arrange bricks around the pipe. Ø Then pour sand to cover it. Ø Make a border to pipe. Ø Connect the wire into home.  Conclusion: §   Water will always near to earthing in earth. §   This place w...

Aim: Information about casing and capping practically. Tools: §   Tester §   Stripper §   Plier §   Screw driver §   Drill machine §   Plumb board §   Hammer §   Level tube Material: §   Board §   wires §   Casing and Capping §   Tubes(Patti) Process: ·        First you should know the height from the floor where you are going to work its important. ·        Using a plumb board make a straight line where you going to do casing. ·        Drill holes to wall where you want to fit casing. ·        Then fit casings using the screws. ·        After this fit electric board in proper place. ·        Then connect all joints properly. ·        Test it by switching on one time then fi...

Aim: Getting knowledge about bio gas practically Requirement : Calculator, Tape Process: ·        First we want to measure the area of tank. ·        Then measure the height of tank. ·        Formula is     pie r2xh=Volume. ·        After this we will get volume of tank. ·        Then subtract height from volume of tank. ·        You will get the quantity of gas inside. ·        When we add hot water into biogas its gas quantity increases,4ltrs 70cm to 75cm ·        When its morning tanks height is75cm, in afternoon tanks height is increased to 80cm. (when we put 5kgs dung into biogas). ·        When we put 4ltrs of hot water in evening tanks height increased 2cm only because...

1)                Starter: - The starter is the part which is stationary & does not move. It contains a coil. 2)                Rotor : - the rotor is the part which rotate because of induction the rotor rotates. It contains in a coil. 3)                Shaft : - the shaft is a rod which connect the imparter to the rotor. 4)                Capacitor : - a capacitor helps to start the motor. 5)                Starting coil: - the coil which is more powerful which help to start the motor 6)                Running coil: - the coil which help to keep the motor...

Aim: - Rewinding a motor… Tool: - wire cutting, spanner, screw drive… Material : - copper wire, cotton thread, varnish PVL paper, capacitor, screw connector, sleeve… 1 horsepower motor .... Procedure : - 1) we disassembled the motor according to the earlier motor practical. 2) the important paint is to coil count the turn of coil. 3) the fault was the coil was short circulated. Observation :- 1) while filling the coil we should fill in one direction , otherwise the motor will not work. 2) while filling the coil there should be no damage or any types of pressure on it, doing that will damage the coil you will damage the coil you will have to rewind the motors again… Conclusion : - if the coil get short circuit at any point will have rewind the motors again…

Aim-: working and connection of a motor starter. Requirements-: Tester, series lamp, copper wires. Procedure-: 1) We look a mechanical starter from the artificial pond. 2) We opened it separated the parts and studied them carefully. 3)We checked the no of volt coil on the series lamp. 4)We brushed the contractor as a carbon residue forms after long time of use. 5)We saw the thermal relay that contains a bio-metallic strips. Observation-; while testing the no of volt of coil we saw that when we passed the current through the no of volt coil turned in to electromagnetic. Conclusion-: We concluded that we can use a mcb instead of a motor starter

Aim : - working and connection of tube light, and troubleshooting method… Tools : - Tester, screw driver, series testing lamp… Material : - 1.50 mm   wire, Insulator tape, Ballast starter, tube holder… Procedure : - 1) we brought a tube light which not working. 2) we test the supply wire of tube light. 3) we test a tube light using a series lamp. 4) we checked the connection reoffering from a circuit diagram. 5) we trouble shouted the tube light and ballast.  Observation : - 1) we observe that the tube light was successfully passed the trouble shooting test. 2) secondly we checked the started it was working in a good condition. 3) thirdly we checked the ballast it was working… Conclusion : - after 1 hour of work we concluded that the problem was with the faulty wiring…
