Energy harvest split core design elements for ease of installation, high performance, and long term reliability

A power line sensing device, comprising:

• a split-core transformer comprising a first core half having a first core face and a second core half having a second core face;
• a hinge attached to one adjoining side of the first core half and the second core half, the hinge being sealed, the hinge being sealed via a flexible boot applied around a gap between the first core half and the second core half;
• and
• a clamping mechanism that, when the power line sensing device is installed, joins the first core face to the second core face around a power line conductor.

• a clamping mechanism that, when the power line sensing device is installed, joins the first core face to the second core face around a power line conductor;
• a seal positioned between the first core face and the second core face;
• a grip pad disposed on an interior of the split-core transformer, the grip pad configured to increase friction between the split-core transformer and the power line conductor;
• and
• a spring configured to push the power line conductor into the grip pad.
