Abstract
An enclosure for an energy monitoring current transformer includes upper housing that houses an upper transformer core section. Lower housing houses a transformer coil and a lower transformer core section. When the enclosure is assembled there is an overlap between the cap for the lower housing and the lower housing that lengthens a creepage path from the upper transformer core to the external surface of the enclosure.
Claims8
An enclosure for an energy monitoring current transformer, the enclosure comprising:
- upper housing that houses an upper transformer core section;
- lower housing that houses a transformer coil, wherein when the enclosure is assembled there is an overlap between the upper housing and the lower housing of at least 8 millimeters;
- a cap for the upper housing, wherein when the enclosure is assembled there is an overlap between the cap for the upper housing and the upper housing of at least 7 millimeters;
- and,
- a cap for the lower housing, wherein when the enclosure is assembled there is an overlap between the cap for the lower housing and the lower housing of at least 12 millimeters;
- wherein the cap for the lower housing includes wire guides that guides lead wires from the transformer coil through the overlap between the cap for the lower housing and out holes in the lower housing.
