CS6456 Notes

1.Object–Oriented Programming Concepts:

The important concept of OOPs are:

Objects, Classes, Inheritance, Data Abstraction, Data Encapsulation, Polymorphism, Overloading, Reusability.

Objects:

Object is the basic unit of object-oriented programming. Objects are identified by its unique name. An object represents a particular instance of a class. There can be more than one instance of an object. Each instance of an object can hold its own relevant data.

An Object is a collection of data members and associated member functions also known as methods.

Classes:

Classes are data types based on which objects are created. Objects with similar properties and methods are grouped together to form a Class. Thus a Class represent a set of individual objects. Characteristics of an object are represented in a class as Properties. The actions that can be performed by objects becomes functions of the class and is referred to as Methods.

For example consider we have a Class of Cars under which Santro Xing, Alto and WaganR represents individual Objects. In this context each Car Object will have its own, Model, Year of Manufacture, Colour, Top Speed, Engine Power etc., which form Properties of the Car class and the associated actions i.e., object functions like Start, Move, Stop form the Methods of Car Class. No memory is allocated when a class is created. Memory is allocated only when an object
is created, i.e., when an instance of a class is created.

Inheritance:

Inheritance is the process of forming a new class from an existing class or base class. The base class is also known as parent class or super class, The new class that is formed is called derived class. Derived class is also known as a child class or sub class. Inheritance helps in reducing the overall code size of the program, which is an important concept in object-oriented programming.

EE6401 Question Bank Electrical Machines 1 Regulation 2013 Anna University

Sample EE6401 Question Bank:

1. Mention the difference between core and shell type transformers.
In core type , the windings surround the core considerably and in shell type the core surround the winding.

2. What is the purpose of laminating the core in a transformers ? (April –98) To reduce eddy current loss.

3. Give the emf equation of a transformer and define each term (April –99)
Emf induced in primary coil E1 = 4.44 fΦ mN1 volt
Emf induced in secondary coil E2 = 4.44fΦ mN2 volt
Where f is the frequency of AC input
Φ m is the maximum value of flux in the core
N1, N2 are the number of primary and secondary turns.

4. Does the transformer draw any current when secondary is open ? Why ?
Yes,it (primary) will draw the current from the main supply in order to magnetise the core and to supply iron and copper losses on no load . There will not be any current in the secondary since secondary is open.

5. Define voltage regulation of a transformer (April –98)
When a transformer is loaded with a constant primary voltage , the secondary voltage decreases for lagging power factor load, and increases for leading pf load because of its internal resistance and leakage reactance . The change in secondary terminal voltage from
no load to full load expressed as a percentage of no load or full load voltage is termed as regulation.
% regulation down = (0V2-V2) x 100/0V2
% regulation up = (0V2-V2) x 100/V2

6. Full load copper loss in a transformer is 1600 watts. What will be the loss at half load ?

If x is the ratio of actual load to full load then copper loss = x2(full load copper loss).Here Wc = (0.5)2 x 1600 = 400 watts

EE6401 Important Questions Electrical Machines 1

EE6401 Important Questions Electrical Machines 1 Regulation 2013 Anna University

Sample EE6401 Important Questions:

1. Mention the types of electrical machines.

There are three basic rotating machines types, namely
a. The dc machines
b. the poly phase synchronous machine (ac), and
c. Poly and single phase induction machine (ac)and a stationary machine,
namely Transformer

2. State Ohm’s law for magnetic circuit.

It states that the magneto motive force across the magnetic element is equal to the product of the magnetic flux through the magnetic element and the reluctance of the magnetic material. It is given by
MMF = Flux X Reluctance

3. Define leakage flux

The flux setup in the air paths around the magnetic material is known as leakage flux.

4. Define magnetic reluctance

The opposition offered by the magnetic circuit for the magnetic flux path is known as magnetic reluctance. It is analogous to electric resistance.

5. What is magnetostriction?

When ferromagnetic materials are subjected to magnetizing mmf, these may undergo small changes in dimension; this phenomenon is known as magnetostriction.

6. What is fringing?

In the air gap the magnetic flux fringes out into neighboring air paths due to the
reluctance of air gap which causes a non uniform flux density in the air gap of a
machine. This effect is called fringing effect.

7. State stacking factor.

The stacking factor is defined as the ratio of the net cross sectional area of a magnetic core to the gross cross sectional area of the magnetic core. Due to lamination net cross sectional are will be always less than gross cross sectional area. Therefore the value of stacking factor is always less than unity.

8.Mention some magnetic materials

Alnicos, chromium steels, copper–nickel alloy, nickel, cobalt, tungsten and aluminium.
