dc.description.abstract |
Electricity is the primary source of power in most countries including Sri Lanka, and saving or
minimising the waste of it has become crucial in facing the world power crisis. Electrical power is wasted
in various ways including reactive power waste due to induction and capacitance of appliances, and standby power loss. These two contribute most to the waste. This paper focuses on reducing the reactive power
waste of inductive electrical appliances commonly used in home and office by increasing the power factor.
An attempt was made to reduce the power waste of inductive electrical appliances by connecting a
capacitor bank with a variable capacitance in parallel with the appliance. Optimal capacitance and the
power factor are determined using the capacitor bank. Results indicate about 30 percent of power saving
could be achieved for fluorescent tube lamps using a power factor correction. A maximum power factor
of 0.93 is achieved at the capacitance value of 2.99 F. It is not possible, by this method, to increase the
power factor of more capacitive equipment such as CFL bulbs and ceiling fans. In this case, power
minimisation could be tried connecting inductors in parallel with the equipment. Power factor and power
consumption of home electrical appliances were measured for advising the general public of high power
consuming equipment, especially in stand-by mode. To attain a further reduction of power waste it is
proposed to measure inductance, capacitance and resistance of appliances using Hendry, Farad and Ohm
meter. Total impedance can then be calculated and the power waste could be minimised using appropriate
capacitors and/or inductors. |
