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...
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.
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.
