Parameter monitoring equipment for electrical power transformer center.

摘要

It effects measurements of the established parameters of the electrical power transformer center in a continuous manner and informs of the status of the center. It incorporates a converter module (1) to measure the parameters, and which is connected to a measurement adquisition module (2) and to the different elements in the transformer center (7). The measurement adquisition module (2) converts the analogue levels of the measurements to logic levels; it is also connected to a storage module (3) and a control module (4) that processes the obtained parameter values. The measurement adquisition module (2) has digital inputs (9) that indicate the state of the different devices in the transformer center (7). The control module (4) is connected to a driver module (6) that is connected to the operating devices of the transformer center (7). The storage module (3) and the control module (4) are connected to a communication module (5) which, in turn, is connected to the medium voltage power line (11) and can be connected to a portable equipment (12), to permit communication with external circuits. <IMAGE>
