摘要： Apparatus and methods are provided for the measurement of power consumption at points of interest, such as circuit breakers, machines, and the like. Accordingly, means are provided for measurement of power consumption for each electrical sub-network that is controlled by a circuit breaker. Each apparatus is enabled to communicate its respective data, in an environment of a plurality of such apparatuses, to a management unit which is enabled to provide finer granularity power consumption profiles. Challenges of measuring relatively low supply currents, wireless operation in an environment of a large number of apparatuses, and self-powering are addressed.

摘要： The invention is an arrangement of inductive voltage transformers for installation in a completely insulated high-voltage switching installation comprising a metal encapsulation and several high-voltage conductors. In accord with the invention each of the inductive voltage transformers includes an insulating body carrying a respective high-potential winding, and each further includes a bushing laterally joined to its respective insulating body. More particularly, in further accord with the invention the bushings are arranged so as to be continuations of the high voltage conductors of the switching installation when the transformers are disposed therein. Moreover, the remaining portions of each one of the voltage transformers are located in a respective space which is defined by the bushing forming that one voltage transformer, the bushing of the voltage transformer following that one voltage transformer in the circumferential direction, and by an area between such bushings which lies adjacent the portion of the metal encapsulation when the arrangement is disposed within such portion.

摘要： A measuring transformer arrangement for several high-voltage conductors disposed in a gas-filled tube includes current transformer units corresponding to respective ones of the highvoltage conductors. The current transformer units form a cohesive structural unit and each current transformer unit has at least one iron core of its own with a secondary winding system mounted thereon. Each iron core of the current transformer units is shielded with respect to high-voltage from the corresponding high-voltage conductor by a control electrode which is at or near ground potential.

The power system can also include at least one second instrument transformer coupled to the second regulated transformer. The power system can further include a controller coupled to the at least one first instrument transformer and the at least one second instrument transformer, where the controller adjusts the first tap changer to a first adjusted position among the first positions based on the first measurements of the first regulated transformer and the second measurements of the second regulated transformer.
