- 3. Power Meters • The Power Analyser saves all the measured data on a SD memory card. • The Power Meter can be used to measure the capacity as well as to perform an analysis on the network. • Harmonics analysis with optional current clamps
- 4. • Range up to 9999 MW. • voltage measurement: 10 - 600 V AC current measurement: 20 -1,200 A AC (Set 1); 30 ... 3,000 A AC (Set 2) • performance measurement: 0 kW ... 9,999 MW (VA/VAR)
- 5. Clamp Meter • A clamp Meter is an electrical device having two jaws which open to allow clamping around an electrical conductor. • This allows properties of the electric current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe • Mostly used for Ac currents.
- 7. Line Tester • Phase or Line Tester is a tool which is used to identify or test the Phase/Live/Hot or Positive wire/Conductor.
- 8. Continuity Tester • A continuity tester is used to determine if an electrical path is complete or Not. • Commonly used to check sockets • It consist of a light and a battery connected in series and glows when path is completed.
- 9. Non Contact Tester • During Flow of current, flow of electrons causes Magnetic field to be generated around wire. • These electromagnetic waves can induce a current on the secondary wiring inside the tester causing the inside bulb to glow.
- 10. Nut Drivers • A nut driver is a tool for tightening nuts and bolts. • They are typically used for lower torque applications than wrenches.
- 11. Drills And Its Types Manual DrillsHand Drill Brace Drill • The brace drill has a top spindle that is used for gripping and fixing the drill in a desired position • While one hand holds the top spindle, the other hand rotates the second spindle in a clockwise motion, so as to make the bit drill a precise hole through wood. • It known as the eggbeater drill • This type of drill has a drive wheel that is spun by turning handle. • The motion of the wheel makes the gear of the drill move along with the chuck, which in turn, causes the attached bit to rotate.
- 12. Electrical Drills Corded Drill • Compact corded drills require a constant supply of power. • corded drills are more powerful and provide greater torque. Hammer Drill • A hammer drill uses rapid and short motions to pound through concrete, stone, and thick blocks of metal. • Hammer drills can have either or both rotary as well as hammer actions
- 13. Cordless Drills • Cordless drills are shaped exactly like corded drills • The only difference being that these drills function on batteries and are much more lighter • The biggest advantage of cordless drills is the mobility it offers to its user. These drills can be carried in the tool kit and used in remote areas that have no power outlets. • Types of battries used are heavier nickel-cadmium, and expensive and lighter lithium- ion batteries. • It is not suitable for heavy drilling work • It would work on wood, thin metal sheets, fiberglass, and plastic.
- 14. Basic Internal Structure of a Drill • Motor causes the gears to rotate and which results in rotating the drill bit which then used for drilling.
- 15. Adjustable Can Light / Speaker Hole Saws • Cuts drywall and ceiling tile • Self-sharpening carbide coated stainless steel blades
- 16. Temperature Controlled Soldering Iron • A soldering iron is a handtool used in soldering • It supplies heat to melt solder so that it can flow into the joint between two work pieces. • Temperature can be controlled using the.
- 17. Soldering Gun • A soldering gun is an approximately pistol - shaped, electrically powered tool for soldering metals using tin- based solder to achieve a strong mechanical bond with good electrical contact. • Soldering guns are used where more heat is needed than from the lower- power soldering iron.
- 18. What is plier A variously shaped hand tool having a pair of pivoted jaws, used for holding, bending, or cutting
- 19. Types of plier
- 20. Names of pliers and Their Uses • Slip joint pliers are pliers whose pivot point or fulcrum can be moved to increase the size range of their jaws. Most slip joint pliers use a mechanism that allows sliding the pivot point into one of several positions when the pliers are fully opened.
- 21. Linesman pliers • It is a type of pliers used by electricians primarily for gripping, twisting, bending and cutting wire and cable. Linemen's pliers owe their effectiveness to their plier design, which multiplies force through leverage Needle-nose pliers • Also known as pointy-nose pliers, long-nose pliers, pinch-nose pliers or snipe-nose pliers • It is also used for cutting and holding wires. • Pliers used by artisans, jewelry designers, electricians, network engineers and other tradesmen to bend, re-position and snip wire.
- 22. Crimping is joining 2 pieces of metal or other ductile material (usually a wire and a metal plate) by deforming one or both of them to hold the other. The bend or deformity is called the crimp. • Round nose pliers, rosary pliers or snub-nose pliers are a specialized plier characterized by their rounded, tapering jaws . • Most commonly used for creating loops in pieces of wire by electricians and jewelers. • Some round nose pliers have insulated handles for safe electrical work. • a spring-fitted joint and comfortable grips on the handles.
- 24. Wire Stripper A wire stripper is a small, hand-held device used to strip the electrical insulation from electric wires. There are three types of stripper.
- 25. Manual Stripper • A simple manual wire stripper is a pair of opposing blades much like scissors or wire cutters. The addition of a center notch makes it easier to cut the insulation without cutting the wire. This type of wire stripper is used by rotating it around the insulation while applying pressure in order to make a cut. Since the insulation is not bonded to the wire, it then pulls easily off the end. This is the most versatile type of wire stripper.
- 26. Automatic Stripper • an automatic wire stripper simultaneously grips the wire from one side and cuts and removes the insulation from the other. To use it, one simply has to place the wire in the jaws and squeeze the handle. While this device allows even a novice to strip most wires very quickly
- 27. Laser Stripper • A laser wire stripper is a computer controlled machine, much like a CNC router, which uses a laser to burn off the insulation of the wire
- 29. Screw Driver Screw Driver was invented in 1908 by Peter Robertson.. A screwdriver is a tool, manual or powered, for turning screws. A typical simple screwdriver has a handle and a shaft, and a tip that the user inserts into the screw head to turn it
- 30. Type of screw drivers
- 31. Names of different type of screwdriver and their work Slotted This is the original screw drive. You find these everywhere, though the practice of using screws with slotted drives is on the decline because the screwdriver slips out of the slot, particularly when you are applying heavy torque to really tighten down (or loosen, for that matter) these types of screws
- 32. Phillips Screw Driver.. This screw drive type is very popular – and again, you find them in a very wide range of applications. Common sizes are Phillips #1, #2 and #3. The most common Phillips size is #2
- 33. Square recess are being used more and more as they are very resistant to cam-out, which is a fancy way of saying the tip of the tool does not slip out and mar the screwhead very easily. Commonly found in two sizes: Square #2 and #3
- 35. What is tool? A tool is an object used to perform work..
- 36. How dangerous are tools? • Tools kill or injuries thousands of workers each ear . • Less dramatic accident injuries and main construction workers every day . • Many injuries happen because tools where: • 1) Modified • 2) Defective and • 3)Use improperly
- 37. Basic tools safety rules • Maintain regularly • Use right tool for the job • Inspect before work • Operate accordingly to manufacturer’s instruction. • Use the right personal protective equipment (PPE) • Use guards
- 38. PPE (Personal Protection Equipments) • Goggles / Face shield (while working with obsasive wheels … • Saftey shoes must be worn • Additional PPE may be required based on the job at hand (long sleves , long pants , anti vibration gloves )
- 39. Electrical Hazards • Be sure that tool is not sparking . • Be sure that tool is properly grounded, espatially when working in wet areas • Turn off and unplug the tools before attemping adjustments or cleaning..
