Test Preparation

In this lesson I have discussed Blondel's Theorem in detail.

Blondel's Theorem (in Hindi)

In this lesson I've discussed two Wattmeter Method and consider the case of star connected balanced load system and find the reading of two Wattmeters using phasor diagrams.

Two Wattmeter Method (Part 1) (in Hindi)

In this lecture I have discussed two wattmeter method when the load is balanced Delta connected. And I have derived the readings of both wattmeters with the help of phasor diagram and after that we at the readings of both wattmeter to get the reading of active power in a three phase system.

Two Wattmeter Method (Part 2) (in Hindi)

In this lesson I have discussed how to calculate reactive power and power factor by two wattmeter method and also discussed some important phase angle where what is the reading of first Wattmeter, what is the reading of Second Wattmeter, what is the reading of active power and what is the relation between first and second Wattmeter.

Two Wattmeter Method (Part 3) (in Hindi)

In this lesson I have discussed errors in the wattmeter like error due to MC-connection, error due to LC-connection and error due to potential coil inductance.

Errors in the Wattmeter (in Hindi)

In this lesson I have discussed the construction and working of energy meter. Type and working principle of energy meter. Also Discussed how driving or deflecting torque developed in energy meter that rotates the disc from its starting position.
An electricity meter, energy meter is a device that measures the amount of electric energy consumed by a residence, business, electrically powered device

Energy Meter

In this lecture I have discussed the derivation of driving torque equation for energy meter with the help of phasor diagram. Construction and working of energy meter. Single phase induction type energy meter.

Derivation of Driving Torque Equation for Energy Meter

In this lecture I have discussed the concept of shading ring an error in the energy meter. In shading ring I have discussed that shading ring provides additional lagging flux which when added to the potential coil flux then the angle between resultant flux and potential coil voltage will be 90 degree so that shading ring make the angle of delta equal to 90 degree by providing lagging flux in the energy meter. And in error in the energy meter we discuss the formulae of energy constant (K), Measured energy(Em), true energy(Et) and percentage in the energy metre

Shading Ring & Error in the Energy Meter

In this lesson I have discussed friction compensation and creeping error. Generally fractional error is introduced at very light load condition in the energy meter. To remove fractional error we use some technique that is called friction compensation of energy meter. We use shading ring to remove frictional error by increasing the value of driving torque. And creeping error is introduced due to over compensation of friction error. There is two method to remove creeping error. One is fix the iron piece at the edge of aluminium disc and another is drill holes
 at diametrically opposite of AL disc.

Friction Compensation & Creeping Error

In this lecture I have discussed the concept of Phantom loading Arrangement in energy meter. We use Phantom loading for calibration of energy meter because we never calibrate the energy meter at full load because at full load we waste a lot of energy in calibration. And we also saw the difference between Phantom loading and direct loading. And at the end we discuss Summary of this course.

Phantom Loading Arrangement

(Hindi) Part 5: Electrical and Electronics Measurements

Engineer,enthusiast,learner ,dreamer,love reading, on the road for transformation.

Deepika Pant

This course basically deals with the basics of electricity, its history and evolution. 
Electricity is as important as air now a days so knowing concepts of electricity and working of different electrical appliances can help you in your day to day life.
Moreover for electrical engineers before going into the hard core subjects like power systems and machines ,knowledge of these basics is important .
The course covers topics like :
1) how does electricity reach us?
2)Concept of ground and neutral.
3) Working of common household appliances. 
4) Power rating of different household appliances etc.
