Power quality “Power quality” can seem to be a pretty abstract term – how does one judge the quality of such an unseen commodity as electricity? But, as commercial and industrial facility managers know, good power quality can boost both productivity and employee safety, while poor power quality can mean a drain on the bottom line, thanks to damaged equipment, lost productivity and product spoilage...

Voltage Sag Voltage sag is the main problem to cause the losses of industrial production. Unpredictable outage rarely happen in many high automated process control industries. who have the good power supplies. Voltage Sag is mostly caused by thunder,but it also has other reasons. Power system cause: starting of heavy machine and short circuit fault. Unpredictable accident:traffic accident,construc...

STATCOM STATCOM (Static Synchronous Compensator)continuously provides variable reactive power in response to voltage variations, supporting the stability of the grid. STATCOM operates according to voltage source converter (VSC) principles, combining unique PWM (pulse width modulation) with millisecond switching. STATCOM functions with a very limited need for harmonic filters, contributing to a sma...

Relations between Reactive power,power factor and penalty Power Factor penalty is spelled out in the contract between the Power Company and Industrial or Commercial customer with large three phase loads. If the contract calls for 85% Power Factor, once the customer’s power factor falls below 85%, the Power Company bills the Customer according to the agreed penalty rates. Industrial loads are mostl...

As an inexpensive source of reactive power, capacitor banks bring many benefits to a facility. They are widely deployed to avoid penalties on utility bills, lower distribution losses, increase transformer/Genset capacity, maintain nominal voltage, and to reduce energy losses resulting in decreased carbon emissions. When coupled with reactors, capacitor banks can filter harmonics generated by...
