NOTE
The Measuring Head window insulation rating is directly proportional to the clearance of the
head to the bus. For instance, a bus in direct contact with the window insulation of the head will
have an insulation rating of 6kV. A clearance of 1" increases the window insulation rating to 12
kV. Thus, the greater the distance through the air between the bus and the head, the greater
the insulation rating will be.
