An electrical power transmission system includes electrical insulators arranged to electrically isolate live power lines. Surface reconditioning units are incorporated or integrated in the insulator structures. A sensor arrangement determines surface conditions of the electrical insulators in use to isolate live power lines. In response, the surface reconditioning units automatically recondition the surfaces of the in-service electrical insulators if appropriate for maintaining the electrical insulators in healthy state.
