1) When buying a new washing machine, always buy from a reputable dealer, and follow the manufacturer’s instructions. 2) When purchasing a washing machine, think about how much it will be used. A large capacity washer should be considered for frequent bigger loads. 3) Check that your washing machine has a Indian standard plug, but if it doesn’t, do not use a Indian travel adaptor, but rather have the retailer fit the washing machine with a Indian standard plug. 4) Do regular checks of the plug and socket for burn marks, sounds of ‘arcing’ (buzzing or crackling), fuses blowing, circuit-breakers tripping or if it feels too hot to touch. 5) Ensure your home is fully protected by an RCD or residual current device, which can be found in your fuse box (also known as a consumer unit). An RCD is a life-saving device that protects against dangerous electric shock and reduces the risk of electrical fires 6) Never overload the washing machine 7) Try to avoid leaving a washing machi...

Low Voltage Switchgear involves switches like power circuits, relays etc. It is important that a periodic inspection and test carried out at least every 1-2 years and 2-6 months when new equipment is installed. In this section we discuss about some guidelines for inspection and maintenance of low voltage switch gear 1)       On energized equipment                              Three things you must do a)       Listen for popping, spitting or cracking sound produced by the electrical discharges-also humming and vibrations produced by the resonance b)       Look for corona halos c)       Check for ozone – ozone is produced by corona or overheating of organic materials 2)       On de-energized equipment’s Three things you must do a)       Check and co...

Insulators are substance which does not readily conduct electricity or Insulators are those substances which offer such a huge resistance. Di-electric strength is the term used for comparing insulation property of an insulator.   Properties An ideal insulator has the following properties a)       High Resistivity Insulators are those substances which offer such a huge resistance, that they allow practically no electricity. b)       Di-electric strength All insulator conduct electricity if subjected to apply extreme voltage. The voltage at which the material lost his insulating property is known as di-electric strength or breakdown voltage. c)       Mechanical strength The insulating material must be mechanically strong enough to carry tension and weight of conductor d)      Ability to withstand moisture Their must not be any entrance on the surface of electrical in...

A generator is a machine which converts the mechanical energy into electrical energy. It works on the principle of Faraday's law of electromagnetic induction. DC Generators produce the direct current. Ordinary generator working             The figure shows two pole and one coil generator, two slip rings are connected with the two terminals of the coil.  Figure 1: The coil is at 90 degree to the field, there will be no cutting of flux so no emf is produced Figure 2: The coil sides are parallel to the field; hence maximum emf will be induced Figure 3: The coil is in the same position as in figure 1, but ab side is downwards and cd is upwards, there is no voltage will be induced. Figure 4: It is similar to figure 2, maximum emf is induced but in the reverse direction. Figure 5: In this way a cycle of ac voltage is completed.  Commutation Commutation in a dc machine is the process of converting alternating c...

Conductors are materials with electrons are loosely bound to their atoms or materials that permit free motion of a large number of electrons. Atoms with only one valance electron such as copper, silver, gold are examples of good conductors. Most of the metals are good conductors Properties of electrical conductors             In equilibrium condition the conductors exhibit the following properties a)       Resistance Conductors are those substances which offer such a small resistance b)       Inductance When a conductor is used as ac supply a magnetic flux is produced, which consist of two parts. One is internal flux and other is external flux. The internal flux is very low as compare to external flux. Due to this flux linkage to the conductor itself an inductance is come into picture. This inductance results in extra voltage drop in conductors. More over this induct...

CHAPTER 1 LITERATURE SURVEY           The method that is followed by energy providing companies, in this generation is, there are large numbers of employees that are placed to take the energy meter reading manually. It is taken once in a month, throughout the year. The readings are taken and noted in their dairy, which is then submitted to the utility company. The bill is then printed and sent to their respective homes. This is the process that is followed until this day. This process has certain disadvantages. They are:                i.      An hefty amount of money is spent on employees assigned for data collection.This is in terms of wages, allowances, perks, pensions, etc.              ii.      May take faulty reading unknowingly by an employee during data collection.That ...
