Why insulators used in electrical system ?

-

 


● Did you know why insulators are in our electrical system ?
   The insulator is a very crucial part of our electrical system. It is used  for safety to separate two energised or non energised parts of electrical equipment or in transmission and distribution system.
     The most important role of insulators in generation, transmission and distribution. This insulators mainly made up of porcelain.
 Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves. 
     An insulating material used in bulk to wrap electrical cables or other equipments is called indulation. The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmision towers.
    They support the weight of the suspended wires without allowing the current to flow through the tower to ground.
   The different insulators are used for different applications are :- 
  • Pin insulators.
  • Stay insulators.
  • Suspension type insulators.
  • Strain type insulators.
  • Disc type insulator.
 Their rating also changes with change in voltage level.
As above else the insulators are very important.

Main parts of transformer.

Transformer :-     Transformer is static device or which transfers AC power from one circuit to another without change in frequency. The main parts of transformer are as follows:-  Three limb core. LV winding. HV winding. Tapped winding. Tap leads. LV bushings. HV bushings. Frame. ON load tap changer. Conservator tank. Radiator. Breather. Test valve. Temperature and oil level indicators. Buccholz relay.   We transformer there is no change on frequency from No load to full load. The voltage level can be changed either it stepped up or down according to need. The transformer is very crucial device in electrical system now days, Without it we can't run our system efficiently. There are two main type of transformer:-  1. Power transformer. 2. Distribution transformer. Other some special types of transformer are there used for special purpose only like, isolation transformer, instrument and welding transformer etc.

Electrical terms.

Basic electrical terms. Alternating Current (AC)  — An electric current that reverses its direction many times a second at regular intervals. Ammeter  — An instrument for measuring the flow of electrical current in amperes. Ammeters are always connected in series with the circuit to be tested. Ampacity  — The maximum amount of electric current a conductor or device can carry before sustaining immediate or progressive deterioration. Ampere-Hour (Ah)  — A unit of measure for battery capacity. It is obtained by multiplying the current (in amperes) by the time (in hours) during which current flows. For example, a battery which provides 5 amperes for 20 hours is said to deliver 100 ampere - hours. Ampere (A)  — A unit of measure for the intensity of an electric current flowing in a circuit. One ampere is equal to a current flow of one coulomb per second. Apparent Power  — Measured in volt-ampers (VA). Apparent power is the product of the rms voltage and the rms current. Armature  — The mova

Why induction motor is self starting and synchronous motor ia not?

Q - Why induction motor is self starting and synchronous motor is not ? Ans_    A 3- phase supply given to the armature of Induction Motor produces a rotating magnetic field. This rotating magnetic field rotates at synchronous speed Ns = (120xf)/P This rotating magnetic field links to the rotor coils and induces voltage which in turn produces current in the rotor. The current carrying rotor being placed in a magnetic field experiences a torque and hence begins to rotate in the direction of rotating magnetic field. Thus we see that Induction Motor is self-starting. It does not require nay external mean to rotate. Now we consider a 3-phase synchronous motor. A 3-phase supply is given to the armature of Synchronous Motor, produces a rotating magnetic field. However, in this case, the rotor has its own field produced by a DC current flowing through the rotor winding. This rotor field tends to align itself along with the rotating magnetic field produced by the stator i.e. armature winding.
