This question often arises, and the answer is usually no for the following reasons: • Grounded capacitor banks can interfere with a facilities ground fault protection system and cause the entire facility to lose power (main breaker trip).
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.
EMI can be particularly disruptive in communication systems, leading to data loss or corrupted signals. Y capacitors are used in the filters of these systems to ensure clear communication by grounding the noise. The stakes for EMI mitigation are even higher in medical equipment, where device malfunction could endanger lives.
A solution is to create a circuit board that establishes a ground with the characteristics of node_G. The principle is simple—the circuit trace from the input ground terminal to the ground side of R1 should be a clear path with no connections to contaminating sources of current along the way (figure 2).
There are two important reasons why every integrated circuit (IC) must have a capacitor connecting every power terminal to ground right at the device: to protect it from noise which may affect its performance, and to prevent it from transmitting noise which may affect the performance of other circuits.
Y capacitors are often found in the input and output filters of these power supplies to minimize the noise conducted through the lines. EMI can be particularly disruptive in communication systems, leading to data loss or corrupted signals. Y capacitors are used in the filters of these systems to ensure clear communication by grounding the noise.
