The capacitor usually consists of two conductors separated by an insulating substance. Among other materials which may be used, a capacitor can be made of aluminum foil separated by oil-impregnated paper.
Ideally, the best electrical supply would be a constant magnitude and frequency sinusoidal voltage waveform. However, because of the non-zero impedance of the supply system, of the large variety of loads that may be encountered and of other phenomena such as transients and outages, the reality is often different. The Power Quality of a system expresses to which degree a practical supply system resembles the ideal supply system.
Low power factor is a problem that can be solved by adding power factor correction capacitors to the plant distribution system.
Correction capacitors work as reactive current generators “providing” needed reactive power (kvar) into the power supply. By supplying their own source of reactive power, the industrial user frees the utility from having to supply it, therefore, the total amount of apparent power supplied by the utility will be less.
At this point, let it suffice to say that keeping the power factor close to 1 is a considerable economic advantage to the utility company and to the consumer. Inductance is the element in the circuit which is pulling the power factor below 1.
The capacitor counteracts this loss of power and makes power production more economical.
After participating in this course, participants will be able to:-
· Analyze the power distribution system in order to determine the need for improvement of power factor
· Calculate energy cost savings associated with the installation of capacitor bank
· Gain the practical knowledge to be able to specify the size and configuration of capacitor bank and associated auxiliary equipment to suit your specific needs
· Optimal location and sizing of capacitors along distribution networks
· Protection schemes for capacitors
· Problems associated with capacitor’s switching and many more
This course is designed for Engineers, technologists and technicians, and other technical personnel from industrial users, power utilities industry, municipal utilities, consulting engineering firms and manufacturers of electrical equipment who are involved with the design, installation, operation and maintenance of electrical power distribution systems. Also plant managers, project engineers, and all personnel involved in the planning, recommending, selling and purchasing electrical distribution systems equipment. This course is a must for people involved in electrical power systems that use capacitors in an industrial plant setting, on distribution feeders and in distribution networks.
