Abstract: A high voltage line post sensor for a high voltage power distribution system having a high voltage power transmission line for transmitting electrical power at a high voltage includes a voltage line sensor. The voltage line sensor includes a high voltage high resistance circuit including a first high voltage high resistance resistor coupled to the high voltage power transmission line and a second high voltage high resistance resistor coupled to the high voltage power transmission line in parallel to the first resistor; and a low voltage low resistance circuit coupled in series between the high voltage high resistance circuit and a reference voltage. The line post sensor also includes a body surrounding and encasing the high voltage high resistance circuit and the low voltage low resistance circuit.
