The Application and Selection of Lightning Arresters
However, it is generally accepted that a rotating machine can withstand a voltage wave at the motor terminals, which rises to a maximum level at a rate not exceeding 1.25 time the crest value of the one-minute hi-pot test voltage in 10 microseconds. Steepness of
Is it healthier for a capacitor to be discharged to itself or to "ground"?
To discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. Whether there is also a connection to some "ground" makes no difference to the process. What you might be seeing is that in a specific circuit, one terminal of the capacitor is already connected to ground (or any other bus / …

Grounding and shielding: No size fits all
If you must connect your shield to ground at the sensor end because of a grounded sensor, then connect the instrument end of the shield to ground through a capacitor. Typically, you''ll find that a ceramic capacitor from 0.01 mF to 1 mF works well.
A Fundamental Rule of Grounding (EE Tip #124)
If the signal grounds of the electronics are not allowed to be connected to the chassis, which depends on the system architecture, a combination of diodes, a capacitor, and a resistor as shown needs to be used to …
Recommended grounding schemes?
My last two amp builds have had problems with grounding, and I realise I need to learn more. I''ve read a few good websites, but I''d bc glad to hear recommendations from others. I''m thinking of busbar versus star, optimal layout, grounding of different stages and any standard guidelines. Thanks...
AC coupling capacitor in the ground to break the …
I thought inserting a capacitor in the way of the ground as shown above would break this ground loop. But apparently, this is not a good idea. Any other suggestions are much appreciated. I am aware of …
Why Your Capacitor Bank Should be Left Ungrounded
Background In general, most industrial facilities with 2.4kV through 13.8 kV distribution are resistive grounded through a grounding resistor as shown in Figure 1. The systems are resistive grounded to reduce the fault current and arc damage during line to ground
Grounding the chassis with capacitor
My question involves chassis grounding to earth ground. My PCB circuit is a simple signal generator using a microcontroller. It has a separate ''ground'' from earth ground, supplied by a floating 5VDC $begingroup$ I doubt your device is shorting for an instant when other machinery is turned on. ...
