customer may affect other customers who share the same communal electrical installation and/or the same supply source. In other words, power quality problems may also originate from the customer side. Generally, the most common power quality problems a customer may encounter include supply interruption, voltage dip and harmonics. 2. This Chapter depicts the causes of the above problems and .

State of Mining in Africa Striking a Balance 2 Mining developments, whether greenfield or brownfield, are not easy and require discerning investors and mining executives to overcome unique barriers that prevent the above five key factors from becoming a constant within the mining project or operation. Looking at the current mining investment,
a. Ensure that equipment or procedure changes which potentially affect operation or reliability of offsite and alternate AC power systems have occurred since the last summer readiness sample. Review the NPP procedures affecting these areas and the communications protocols between the transmission system operator (TSO) and the
Capacity factor provides information on how close the power supply system is to being overloaded or, in other words, to its limit defined by the level of installed capacity. When capacity factor is high (, actual supply is approaching its capacity limit), there is a risk of system overload and power blackout.
