ground loop

However, one has to pay attention to ground loops and power line hum.

The expensive part is drilling to put in ground loops.

The ground loop in such systems can also be placed in a lake, a deep well if one is available or similar.

A ground loop is an electric difference of potential between various ground points throughout the system.

They have no electrical isolation and cannot prevent ground loops.

Often, the second effect is much greater than the first one, leading to higher costs of operation for the more shallow ground loops.

They can also eliminate measurement errors caused by ground loops.

His first attempt at flight ended in a ground loop, which required $100 to repair.

If the grass is long, touching a wing-tip may result in a serious ground loop.

One such source of ground noise is the isolated ground loop.
