Electrical Shock Definition

Electrical Shock Definition :

Electrical Shock, a condition that occurs when there is a flow of electricity through the body.

Causes of an electric shock:

It is usually caused by contact with poorly insulated wires or ungrounded electrical equipment , by using electrical equipment while in contact with water, or by being struck by lightning.

The severity and effects of electrical shock depend on:-

1- The amount of current passing through the body
2- Type of current "AC or Dc"
3- Skin Case "Wet or Dry"
4- The duration of contact

Types of electrical shock:-
1- Small (1-8) mA

=> Not effect on the body

2- Medium (20-50) mA
=> Lead to difficulty in breathing

3- Large (50-100) mA
=> Lead to disturbances in the heart and may lead to death

Protection against electrical shock:-

1- Grounding equipment and electrical devices.
2- The use of cables with good insulation and suitable cross
section area.
3- Use of appropriate breakers to the values of the current.

Armature Winding ,Pole Pitch, Coil Span, Commutator Pitch

Now we are going to discuss about armature winding in details. Before going through this section, we should understand some basic terms related to armature winding of dc generator . Pole Pitch Definition of Pole Pitch The pole pitch is defined as peripheral distance between center of two adjacent poles in dc machine. This distance is measured in term of armature slots or armature conductor come between two adjacent pole centers. This is naturally equal to the total number of armature slots divided by number of poles in the machine. If there are 96 slots on the armature periphery and 4 numbers of poles in the machine, the numbers of armature slots come between two adjacent poles centers would be 96/4 = 24. Hence, the pole pitch of that dc machine would be 24. As it is seen that, pole pitch is equal to total numbers of armature slots divided by total numbers of poles, this can alternatively referred as armature slots per pole . Coil Span or Coil Pitch Coil of ...

Transformer

A transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. The transformer is one of the simplest of electrical devices. Its basic design, materials, and principles have changed little over the last one hundred years, yet transformer designs and materials continue to be improved. Transformers are essential in high voltage power transmission providing an economical means of transmitting power over large distances. The simplicity, reliability, and economy of conversion of voltages by transformers was the principal factor in the selection of alternating current power transmission in the "War of Currents" in the late 1880's. In electronic circuitry, new methods of circuit design have replaced some of the applications of transformers, but electronic technology has also developed new transformer designs and applications. Transformers come in a range of sizes from a thumbnail-sized coupling transfo...
