Impedance assembly () for use in a voltage divider for sensing an AC elevated voltage of at least 1 kV of a power-carrying conductor () distributing electrical energy in a national grid. The impedance assembly comprises a) a PCB (); b) a high-voltage contact () for connection to the power-carrying conductor; c) a first plurality of impedance elements () on the PCB, connected to the high-voltage contact and in series with each other such as to be operable in a first voltage divider () for sensing the voltage of the power-carrying conductor; and d) a second plurality of impedance elements () on the PCB, connected to the high-voltage contact and in series with each other such as to be operable in a second voltage divider () for harvesting electrical energy from the power-carrying conductor.

Impedance assembly

A remote monitoring system for telecommunication enclosures includes a low profile or flush mounted sealed transceiver or antenna unit, an electronic module inside of the enclosure electrically connected to the transceiver and a communication device to send signals to the electronic module through the transceiver. The sealed housing generally comprises a portion extending through the exterior surface of the enclosure. In some embodiments, the transceiver may include a radio frequency antenna, a photoelectric cell, a light sensor or an infrared sensor, and the communication device may be a handheld device, a transponder, or a networked computer.
