1. 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 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; and
a sacrificial metal applied outside of the seal and in galvanic contact with material of the split-core transformer.
