A portable electric fence energizer is described, having a housing and an electric pulse generating circuit located within the housing. The energizer further includes a post securing mechanism configured to secure the housing relative to an electrically conductive post. The post securing mechanism includes at least one electrical contact configured to contact the post when secured by the post securing mechanism. A conductive link between the electrical contact and the electric pulse generating circuit may be used to provide an earth connection for the energiser, or an output connection between the electric pulse generating circuit and a wire of the electric fence.

An extended insulator assembly holds an electrified wire at a distance from the fence. The assembly does not need to be attached at the fence post but can be attached directly to the fencing. The assembly consists of two arms. At one end, the arms have C-shaped structures featuring a channel into which the electrified wire is inserted. The wire is inserted with the two arms combined such that the grooves are aligned. After the wire is inserted, the arms are rotated locking the wire in place and forming a V-shaped structure that both braces the electrified wire and can be attached to the fence line and firmly holds the wire in place at a distance from the fence line.

A portable fence reel has a reel spool, and a frame including at least one arm, where the reel spool is rotatably mounted to the at least one arm. The fence reel also has a crank shaft, where rotation of a crank shaft results in rotation of the reel spool, and a winding handle. An automatic engaging mechanism includes a coupler rotationally fixed to the crank shaft, and a clutch portion configured to be driven by the winding handle and, in use, move along a longitudinal axis of the crank shaft to engage or disengage with the coupler.

An off-line monitoring unit and method for sensing electrical disruptions on an electric fence conductor includes a non-conductive housing, a broad frequency pulse detector housed therein, a controller, and a communication device. The broad frequency pulse detector can include an antenna spaced apart from and positioned within a predetermined distance range away from the conductor being monitored. The controller is coupled to receive current induced on the antenna by high voltage on the conductor and, based on the received current, changes a state of the controller indicating the high voltage stopped inducing the current on the antenna for a predetermined length of time. The communication device, in response to the change of state of the controller, transmits a notification signal to a local notification device or a remote computing device that the conductor is off or inactive.
