SERIES, SHUNT AND COMPOUND GENERATORS
This document discusses different types of DC generators, including series, shunt, and compound generators. It provides the following key details:
1. Series generators have a rising voltage characteristic where voltage increases with load, but voltage starts decreasing at high loads due to armature reaction demagnetizing effects.
2. Shunt generators have a constant voltage characteristic, but voltage decreases slightly with increasing load due to armature reaction and armature drop. Adding a few series field coils can make the voltage substantially constant or rising.
3. Compound generators have both shunt and series field windings, allowing their external characteristics to be adjusted to compensate for line voltage drops. Flat-compound generators aim for constant voltage,

WORKING PRINCIPLE OF DC GENERATOR
A generator is a device that convert Mechanical energy into electrical energy using electromagnetic induction.
A DC generator produces direct power based on fundamental principle of Faraday's laws of electromagnetic induction.
According to this laws, Whenever a conductor is moved within a magnetic field in such a way that the conductor cuts across magnetic lines of flux, voltage is generated in the conductor.
FLEMING’S RIGHT HAND RULE (GENERATOR RULE)
It use to determine the direction of the induced emf/current of a conductor moving in a magnetic field.
The POLARITY of the voltage depends on the direction of the magnetic lines of flux and the direction of movement of the conductor.
Fleming right hand rule (FRR) used to determine nature of emf or direction of current because rest two direction of motion of conductor in generator (Input Mechanical energy in generator) and direction of magnetic field (due to stator Field) are known.
Three phase transformers
This document discusses various types of three-phase transformer connections including:
- Delta-delta, which produces no phase shift between input and output voltages.
- Delta-wye, which produces a 30 degree phase shift.
- Wye-delta, which also produces a 30 degree phase shift with primary and secondary connections reversed from delta-wye.
- Wye-wye requires special precautions like connecting the neutral or using a tertiary winding to prevent voltage distortion.
- Open-delta can transform voltage using only two transformers in an emergency situation but has lower capacity.
- Autotransformers are more economical than conventional transformers for moderate voltage changes between 0.5-2 times.

This document discusses how to prove that a language is not regular using the pumping lemma for regular languages. It provides two examples:
1) It shows that the language Leq consisting of strings with an equal number of 0s and 1s is not regular by pumping a string w in Leq to get a string with an unequal number of 0s and 1s, violating the definition of Leq.
2) It shows that the language Lpal consisting of palindrome strings is not regular by pumping a string w in Lpal to get a string that is not a palindrome, again violating the definition of the language.
Two phase commit protocol in dbms
In transaction processing, databases, and computer networking, the two-phase commit protocol (2PC) is a type of atomic commitment protocol (ACP). ... The protocol achieves its goal even in many cases of temporary system failure (involving either process, network node, communication, etc. failures), and is thus widely used.
Construction oc dc machine
Poles carry field windings and pole shoes, which support the coils and spread flux uniformly in the air gap. The commutator rectifies alternating current to direct current in a generator and inverts direct current to alternating current in a motor, reversing the current through the armature conductors to produce unidirectional torque. Brushes conduct current between stationary wires and the rotating shaft, charging the commutator to cause the armature to rotate in a particular direction by reversing the brush polarity. Field windings are wound copper coils that form north and south poles when energized. Armature windings are wound on a laminated steel core with slots and can use lap or wave winding configurations.

Plant Tissue Culture
Tissue culture is the process of growing plant cells, tissues or organs in sterile conditions on a nutrient culture medium. It relies on the abilities of plant cells to totipotent (form a whole plant), dedifferentiate (lose specialization) and become competent (able) again. The process involves collecting and sterilizing explants (plant tissues), producing a callus (thickened tissue) from the explants, subculturing the callus on fresh medium, and eventually regenerating whole plants. Tissue culture allows for mass production of identical plant materials and preservation of plant germplasm.

Unit ii
This document discusses generators and their components. It describes the key parts of DC generators including the yoke, poles, field winding, armature, commutator, and brushes. It explains how DC generators work using electromagnetic induction to convert mechanical energy into electrical energy. Characteristics of DC generators like open circuit characteristics, internal characteristics, and external characteristics are also summarized.
Dc current
The starting current in a DC motor is high because at startup, when the motor's speed is zero, the back EMF is also zero. With no back EMF, the supply voltage is applied entirely across the armature resistance. This causes the starting current to be very high, around 440 amps for a typical DC motor. Such a high starting current can damage the motor's windings and produce a huge starting torque capable of ripping the rotor from its slots. The starting current decreases as the motor gains speed and the back EMF increases to oppose the supply voltage.

Power Factor its Importance and Improvement.pptx
The document discusses power factor, its importance, causes of low power factor, and methods for improving power factor. Power factor is the cosine of the angle between the voltage and current in an AC circuit. Inductive loads like motors and discharge lamps typically have low lagging power factors. Low power factor is undesirable as it causes increased current, losses, equipment sizes, and reduced system capacity. Common causes of low power factor include inductive motors and loads that vary over time. Power factor can be improved by connecting capacitors in parallel with inductive loads to supply leading current to neutralize the reactive current.

UNIT 1.pptx
The document discusses various methods to determine the voltage regulation of a synchronous generator or alternator. It describes the synchronous impedance method, MMF (ampere-turns) method, and zero power factor (Potier) method. The synchronous impedance method calculates regulation using synchronous reactance Xs obtained from open-circuit and short-circuit tests. The MMF method considers the field mmf required for open-circuit voltage and to cancel armature reaction mmf. The zero power factor method separates armature leakage reactance from armature reaction effects using open-circuit and zero power factor tests.
Ac generator
An AC generator converts mechanical energy to electrical energy by rotating a coil within a magnetic field or rotating the magnetic field around a stationary coil. It produces alternating current unlike a DC generator. The main components of an AC generator are the field, armature, prime mover, rotor, and stator. The rotor is driven by the prime mover and either the rotor or stator contains the field coils. Losses in the AC generator occur due to resistance in the armature windings, hysteresis in the iron cores, and mechanical friction from bearings and windage. The efficiency of an AC generator is the ratio of its output power to input power.

Dc generator with machine 2
- 1. Email- dilouarbd@gmail.com By Dilouar Hossain Topic: DC Generator
- 3. DC Generator Characteristics 1. No-load saturation Characteristic (E0/If) It is also known as Magnetic Characteristic or Open-circuit Characteristic. It shows the relation between the no-load generated e.m.f. in armature, E0 and the field or exciting current If at a given fixed speed. It is just the magnetisation curve for the material of the electromagnets. Its shape is practically the same for all generators whether separately-excited or self-excited. 2. Internal or Total Characteristic (E/Ia) It gives the relation between the e.m.f. E actually induces in the armature (after allowing for the demagnetising effect of armature reaction) and the armature current Ia. This characteristic is of interest mainly to the designer
- 4. 3. External Characteristic (V/I) It is also referred to as performance characteristic or sometimes voltage-regulating curve. It gives relation between that terminal voltage V and the load current I. This curve lies below the internal characteristic because it takes into account the voltage drop over the armature circuit resistance. The values of V are obtained by subtracting IaRa from corresponding values of E. This characteristic is of great importance in judging the suitability of a generator for a particular purpose.
- 5. External Characteristic These are three main reasons for the drop in terminal voltage of a shunt generator when under load. (i) Armature resistance drop : As the load current increases, more and more voltage is consumed in the ohmic resistance of the armature circuit. Hence, the terminal voltage V = E − Ia Ra is decreased where E is the induced e.m.f. in the armature under load condition. (ii) Armature reaction drop: Due to the demagnetising effect of armature reaction, pole flux is weakened and so the induced e.m.f. in the armature is decreased. (iii) The drop in terminal voltage V due to (i) and (ii) results in a decreased field current . If which further reduces the induced e.m.f.
- 6. Shunt-generator characteristics 1.Armature-circuit resistance, 2. Armature reaction, 3. Reduction in the field current.
