How is a capacitor bank re-energized?
The capacitor bank was re-energized at the voltage peak opposite in polarity with the trapped voltage to simulate the maximum transient. Table II shows the transient voltages for different combinations. Table II. Transient peak voltages for capacitor bank re- energization Cap.
What happens if a capacitor bank is de-energised?
The magnitude and frequency of the voltage rise depends on the inrush current, network fault level and X/R ratio. Furthermore, when a capacitor bank is de-energised a residual DC voltage will be left on the capacitors. This commonly means there must be a 6-10 minute delay period while the voltage decays before the bank can be re-energised.
What are the power quality concerns associated with single capacitor bank switching transients?
There are three power quality concerns associated with single capacitor bank switching transients. These concerns are most easily seen in figure 4, and are as follows: The initial voltage depression results in a loss of voltage of magnitude “D” and duration “T1”.
