Types and Usage of Capacitors

posted in: electrikals | 2

          A capacitor is a device with two terminals electrically isolated by insulating medium capable to store electrical energy temporarily. Theoretically it can store energy but capacitors are never used as electrical storage devices as they discharge energy quickly. Capacitors have wide applications in electrical as well as electronic fields. Capacitors are also called as condensers. The capacity of capacitors is defined as capacitance and is measured in Farads. Capacitors with ratings from picoFarads to KiloFarads are manufactured depending on the application.Types and Usage of Capacitors

          Capacitors can be classified into many types depending on the usage. In domestic appliances like fans, it is used for starting and also to improve power factor of fan during running. Also in many home appliances normal capacitors are used. Agriculture motors are highly inductive and increase the reactive currents heavily. To reduce reactive power which is very disadvantage for the power lines, agriculture capacitors are made mandatory by many power utilities. These agriculture capacitors apart from improving power factor also increases the power output of the agriculture motors thereby benefiting farmer as well as power utility.

          In industries, the role of capacitor is even more predominant. Industries have many induction motors and hence produce high reactive power. Reactive power billing is being done in many states which makes elevated bills in case capacitors are not used. Industrial usage capacitors like Power capacitors, Heavy duty extended life capacitors etc are available in the market which will improve power factors. Capacitors are also used in Harmonic filtration system wherein harmonics are suppressed for quality power.

In Sodium Vapour and Mercury Vapour lamps also capacitors are used for the starting and running purpose. These are called lighting capacitors. Capacitors are usually connected in shunt at the load for power factor improvement. In large capacity power capacitors, oil is also used as insulating medium. In large industries these types of oil capacitors are used for power factor correction.

Capacitors according to usage has to be selected and different varieties of capacitors are also available for purchase online at www.electrikals.com

              To lessen the risk of electric power distortion, uninterruptible power supply (UPS) systems are often included in electrical system. The changes such as voltage dips and surges, harmonics, or voltage spikes range in different forms which causes harm to electrical equipment during the operation stages or in particular as processing stages. A UPS system can be helpful equipment for guaranteed proper electric power supply performance either in residential sector or industries. UPS is probably the most commonly known to the average person, but they range from those made for a home-office to those that depends on situation such as

Industrial UPS: For use in industrial/manufacturing situations for plant facilities, industries/ factories.

Medical UPS:  For use in Medical facilities /centers and hospitals, Medical UPS systems are extremely important, as they provide life-support systems and other critical equipment.UNINTERRUPTIBLE POWER SUPPLY (UPS) SYSTEMS AND ITS TYPES

Tele Communication System: For use in Server stations and web hosting places, along with phone companies, computer/communication Industry.

Military Grade UPS system: Military grade UPS systems are certified for quality under the Military -SPEC certification, which are used in military operations throughout the world.

High Temperature UPS System: For use in High Temperature situations which are specially created and suited for High Temperatures.

UPS Performance Characteristics:

UPS systems are in very much needed in situations where power fluctuations or outages frequently occur as they provide backup power that keeps systems running in case the power supply is failed. As of the conditions concerning voltage fluctuations or voltage disruption, it activates reserve electric power to keep systems operating until they can be safely shut down.  UPS systems can often also reduce the risk posed by harmonic disruptions and line transients. An efficient UPS usually includes following features:

  • Synchronized output voltage with low harmonic distortion unaffected by voltage or load changes.
  • An input current with reduced harmonic distortion
  • A low degree of electromagnetic interference and acoustic noise
  • Minimal transition times between normal and backup operations
  • High levels of reliability and efficiency
  • Relatively low cost, weight, and size requirements

As most of all UPS cannot provide all of the features at a time, it is always advised to find a UPS with the characteristics well suited for a need.
