When there is a ground fault in one phase, it results in the following: Fault current can''t flow due to an incomplete path with the neutral point of the 13.8KV winding, as seen in the next simulation. The fault current flows only after another fault occurs on another phase. This turns the fault from a Line-Ground Fault to a Line-Line-Ground
Grounding Considerations for DC and Mixed DC and AC Power
Grounding methods affect common-mode voltage and circulating currents under normal conditions. Ground faults produce fault currents and systemwide offsets throughout the system with respect to ground. During ground fault transients, the aggregate bus-to-ground ground capacitance and inductance produce underdamped oscillatory overvoltages.
6 FAQs about [Capacitor grounding considerations]
Can a capacitor be grounded?
In most cases, one side of a capacitor is grounded. However, it is not true that this is the case in all designs. The only guaranteed safe way to discharge a capacitor is through a suitable resistor across its terminals.
Does grounding a capacitor cause a discharge?
Grounding either pin of a capacitor to frame ground does not necessarily cause a discharge. In fact, it may apply power to some circuit that does not expect it, potentially damaging it.
Do I need to connect a polarized capacitor to ground?
So for capacitors, if a capacitor is polarized (has a + and - node), then all you need is to make sure that the voltage at the + node is greater than or equal to the voltage at the - node. You do NOT have to connect the - node to ground. YOu still need a decent discharge path on that.
What is a grounding configuration?
In addition, the grounding configuration endows the ground fault ride-through capability to the network. While solidly grounded networks have certain positive attributes, their inability to ride-through faults and maintain service in the presence of a ground fault, outweighs in certain applications.
What happens when a capacitor is charged?
When a capacitor is being charged, negative charge is removed from one side of the capacitor and placed onto the other, leaving one side with a negative charge (-q) and the other side with a positive charge (+q). The net charge of the capacitor as a whole remains equal to zero.
Why are capacitors paralleled with smaller values?
This is why in decoupling applications we often see larger value capacitors paralleled with smaller values. The smaller value capacitor will typically have lower ESL and continue to behave like a capacitor at higher frequencies. The parallel combination of capacitors covers a wider frequency range than either one of the combinations. Figure 2.
