Want this question answered?
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
Just checked and it does have a ground connection.
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
How many inches of the ground can my car be if dropped
5 volt supply, sensor ground and signal voltage.5 volt supply, sensor ground and signal voltage.
Because the O'scope and the device being checked must somehow be sharing a common ground. That may be good, bad, or indifferent, depending on the electrical sensitivity requirements of the device being checked. It won't harm a quality O'scope.
Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
I accidently dropped it on the ground!
There is such a thing, what is your question?
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
