To optimize grid operations, concerning energy storage charging piles connected to the grid, the charging load of energy storage is shifted to nighttime to Negative Pole When performing (for example) MIG welding using a consumable wire, the wire is normally connected to
It is negative (i.e., suction or negative pressure under the pile) where the fan draws air through the pile. Positive aeration is simpler and less expensive to implement. It is generally preferred over negative aeration, unless the exhaust gases must be treated to reduce odors or other emissions or if heat recovery is desired.
Blue Jay''s insulation monitoring device is used to online monitor the insulation resistance values of the positive and negative poles of the DC floating system to the ground. It is based on the principle of an unbalanced bridge, which avoids the problem of undetectable ground faults in the positive and negative poles of the balanced bridge.
