TYPES OF ELECTRICAL MEASURING INSTRUMENTS.pptx
- 1. TYPES OF ELECTRICAL MEASURING INSTRUMENTS
- 2. Objectives: After1 hour discussion students should be able to: 1. Identify the different measuring instrument 2. Used the different measuring instrument 3. Perform mensuration and calculation.
- 3. Multimeter
- 4. Multimeters are very useful test instruments. By operating a multi-position switch on the meter they can be quickly and easily set to be a voltmeter, an ammeter or an ohmmeter.
- 5. Clamp meter
- 6. Clamp meter •Clamp meter is another type of measuring instrument which is specialized to measure the value of electric current indirectly in an electrical circuit. This can also be a voltmeter, and an ohmmeter.
- 8. Electric meter •Electric meter is an electrical device used to record the amount of electrical energy consumed by an appliance or electrical system in a particular period of time
- 10. Insulation Tester (Megger) •Insulation tester (megger) is an electrical measuring instrument intended to measure the insulation resistance of electrical conductor. It is particularly used to detect the condition of the coil of an electric motor.
- 11. Steel Rule
- 12. •The steel rule is considered to be the most convenient size to carry around. •This can be used to set calipers, dividers, etc. and to take measurements where it is not possible to make sure that the end of the rule is even with the edge of the work. Some workers refer steel rules as "machinists scales." Steel Rule
- 13. Metric Rule
- 14. •Metric rule is a tool used measure short and long distances. It is very important when performing a layout and installation of electrical wiring fixture. Metric Rule
- 15. Caliper Rule
- 16. •These tools are commonly used to measure the diameter of a wires or thickness of steel plates . •It can also be used to measure the inner distance of a hole. Caliper Rule
