A capacitor bank is a grouping of several identical capacitors interconnected in parallel or in series with one another. These groups of capacitors are typically used to correct or counteract undesirable characteristics, such as power factor lag or phase shifts inherent in alternating current (AC) electrical power supplies. FEATURES: Power factor correction by multi step design Standard & detu...

Why harmonics analysis? When a voltage and/or current waveform is distorted, it causes abnormal operating conditions in a power system such as: Voltage Harmonics can cause additional heating in induction and synchronous motors and generators. Voltage Harmonics with high peak values can weaken insulation in cables, windings, and capacitors. Voltage Harmonics can cause malfunction of different elect...

Power Factor Penalty An electric rate may also include additional charges when the customer has a power factor less than some preset limit, typically between 80 and 90 percent. This is called a power factor penalty since it is a penalty assessed on the customers electrical bill for lower than optimum power factor. Special devices called capacitors can be installed by either the utility or the cust...

Energy demand is anticipated to be double by 2030. CO2 emissions should be halved to avoid global warming acceleration. Both issues place a major challenge on the generating capacity of all utilities, and on us as electricity end users. Energy efficiency becomes more than a cost issue today. It becomes part of the journey to ensure energy availability and preserve the environment in the future. Ma...

ZDDQ-SVG Static Var Generator is an electronic reactive power compensation system, for both capacitive and inductive power. It has the same operating principle as an active filter; the SVG injects a current in the opposite direction to counteract the installation's non-useful power (inductive and capacitive), thus ensuring that the target cosϕ is achieved. ZDDQ SVG instantly compensates and adjust...
