Electric Power Safety Work Procedures Exam Paper (Substation Specialization). The verification of the position of electrical equipment after operation should be based on the actual position of the equipment. When it is not possible to see the actual position, the mechanical position indicators, electrical indicators, meters, as well as various telemetry and telesignaling signals can be used to determine the position; at least two such indicators must show corresponding changes simultaneously in order to confirm that the equipment has been moved to its correct position.
