Losses may increase if ground electrodes and lines are not designed for the extra current in this mode.

The connection into the ground requires a specially designed ground electrode (or earth electrode).

Then the ground electrode is placed in a VAR furnace.

A ground electrode is placed in the center of the patient's forehead, sufficiently far from the facial nerve as to not give an output reading.

The test is performed by attaching electrodes around the nose and measuring the movements of the eye in relation to the ground electrode.

Such variations include the use of two, three, or four equally spaced ground electrodes surrounding the central electrode.

Also there is the use of a V-shaped notch in the tip of the ground electrode.

A "ground" electrode is attached to the forehead.

These electrodes record eye movements relative to the position of the ground electrode.

The ground electrode in Finland is situated near Rantala.
