A wearable static electricity removing device includes a portable device which has a metal sheet; a current limiter for limiting a current flow therethrough; .a high impedance resistor connected to the metal sheet; an impedance of the high impedance resistor being greater than that of the current limiter; a conductive wire having an end connected to the current limiter and the high impedance resistor; and another end of the conductive wire being grounded. In use, when the body of the user has static electricity, the static electricity will pass through the current limiter and then flows to the ground through the conductive wire so as to have the effect of removing the static electricity; and when the user contacts a high voltage which causes the current limiter to breakdown to protect the user, and the static electricity from the user flows through the high impedance resistor.

Disclosed herein is a system for detecting a partial discharge from electrical equipment. The system includes a vest dimensioned for wear by a user. An antenna is associated with the vest, and a receiver is coupled to the antenna and associated with the vest. At least one indicator device is associated with the best. Circuitry is associated with the vest and coupled to the receiver. The circuitry is configured to monitor ambient radiofrequency energy in real time, and determine that the partial discharge has occurred as a function of the ambient radiofrequency energy. The circuitry actuates the at least one indicator device as a function of the determination that the partial discharge has occurred, and transmits the determination that the partial charge has occurred to a control station via the wireless transmitter.

A harness (10) is provided for retaining a pair of electrical rubber insulating workman sleeves (12) on the shoulders (14) of a worker (16). The harness (10) is configured to grip a portion of the worker and thereby provide better anchoring of the electrical rubber insulating sleeves (12) to the worker. The gripping feature of the harness (10) is provided either in the form of a gripping collar (24) or a pair of fabric gripping sleeves (26), or a combination of the collar (24) and sleeves (26). Further, a C-shaped connector is configured for attaching the electrical rubber insulating sleeves (12) to a single point on a harness, which allows for an increased range of motion of the sleeves (12).
