AIM : DEMONSTRATION OF ENERGY METER.
Conclusion: The electronic energy meter is vital in measuring electricity, usage demands, power factor, and voltage. The operators cannot calculate the correct bill amount without an electronic energy meter.
Q1] Discuss the requirement of metering.
Ans : Metering is necessary for accurate measurement and recording of resource usage, such as electricity, gas, water, or data, for billing, monitoring, and analysis purposes.
Q2] Discuss various reasons which introduce errors in theoretical and practical observations in energy meter.
Ans :
- Instrumental Errors: Energy meters, like any measuring instrument, can have inherent instrumental errors due to manufacturing tolerances, aging, and wear and tear of components.
- Calibration Errors: Calibration is the process of adjusting and verifying the accuracy of an energy meter. If a meter is not calibrated or calibrated improperly.
- Environmental Factors: Energy meters can be sensitive to environmental factors such as temperature, humidity, and electromagnetic interference, which can affect their accuracy.
