Power Quality In Electrical Systems

EFFECTS OF HARMONICS ON CAPACITORS

The Effects of Harmonics on Capacitors include additional heating - and in severe cases overloading, increased dielectric or voltage stress, and unwanted losses. Also, the combination of harmonics and capacitors in a system could lead to a more severe power quality condition called harmonic resonance, which has the potential for extensive damage. Consequently, these negative effects will shorten capacitor life. Capacitors are typically installed in the electrical power system – from... (Pl

STATIC SYNCHRONOUS SERIES COMPENSATOR (SSSC)

Static Synchronous Series Compensator (SSSC) is a modern power quality FACTS device that employs a voltage source converter connected in series to a transmission line through a transformer. The SSSC operates like a controllable series capacitor and series inductor. The primary difference is that its injected voltage is not related to the line intensity and can be managed independently. This feature allows the SSSC to work satisfactorily with high loads as well as with lower loads. The... (P

FERRORESONANCE PREVENTION TUTORIALS

Ferroresonance Prevention Tutorials deal with strategies that electric utilities and end-users could implement to minimize occurrence of the power quality phenomenon. These practices are based from the fact that ferroresonance usually happens with lightly loaded three-phase transformer, having one or two phases open either intentionally or accidentally.
