There are many reasons for this but I’d like to focus on African power utilities. Power utilities are a very important part of the chain for delivering electrical power to end users. One of their key roles is to purchase power that has been generated by others, sell it on to end-users and to collect revenues. They are vital for extending grid-based power to consumers and to ensure regular and efficient power supply. As they collect money from end-users and pay it on to other players in the system, they are also vital in ensuring money flows through the entire power sector.
Excessive Total Harmonic Distortions (THD) and not unity Power Factor (PF) is costly at every level of the electricity market. Cost of PF and THD impact is difficult to estimate, but both can potentially cause heat, vibrations, malfunctioning and even meltdowns. Power factor is the ratio of real to apparent power in a power system. Drawing more current results in a lower power factor. Larger currents require costlier infrastructure to minimize power loss, so consumers with low power factors get charged a higher electricity rate by their utility. True power factor is made of displacement power factor and THD. Power quality is typically monitored at the transmission level. A spectrum of compensation devices mitigate bad outcomes, but improvements can be achieved only with real-time correction devices (old style switching type, modern low-speed DSP driven and near real-time). Most modern devices reduce problems, while maintaining return on investment and significant reduction of ground currents. Power quality problems can cause erroneous responses from many kinds of analog and digital equipment, where the response could be unpredictable.
Dallas area residents now have the option for choosing their electric provider. However, with all of the different plans that are available, it can be difficult to make the right decision for your particular electricity needs. You may find yourself overwhelmed by the number of options presented to you by all the electric company advertisements or concerned about shady marketing gimmicks.
