5.1.3: Explain why Supply authorities require the system PF to be greater than 0.8The supply authorities require the system PF to be greater than 0.8 as the reduction in the powerfactor will lead to higher transmission losses. Transmission refers to the supply of electricityfrom the source to the users. The loss of energy, while transmission from one place to another,can lead to unnecessary consumption of resources for electricity production. It will in turnincreases the cost of production which eventually leads to surge in electricity prices. Therefore, itis required by the Supply authorities that the system PF should be greater than 0.8.The PF refers to power factor which the ratio of real power flowing the load to the apparentpower in the circuit. The power factor should be high. The high power factor indicates thattransmission is efficient. The PF value of 1 is considered that ideal which is generally notachieved due to various factors such as the distance of transmission or the material used for thetransmission. Power factor also refers to the cosine angle between the vtg and the current. Theratio of active power and apparent power, the low power factor shows that there is more currentwithin the line in compare to the actual current.
