SYSTEM AND METHOD FOR CENTRALISED MONITORING AND CONTROL OF OPERATION MODE OF POWER TRANSFORMERS INSTALLED IN DIFFERENT SUBSTATIONS AND IN MONITORING CENTRES Russian patent published in 2010 - IPC H02J3/00 H01F29/00 

FIELD: electric engineering.

SUBSTANCE: system comprises multiple substations, besides a control panel connected to power transformer is installed on each substation. At the same time specified control panel receives data related to measurements of specified transformer parametres. And monitoring centre comprises technical server, Internet server and software, which provides for data transfer from specified technical server into specified Internet server. Specified technical server is connected to control panel of each substation, and specified Internet server provides for remote access to system for users of this system. Method comprises stages, at which (a) parametres of multiple power transformers located in multiple substations are permanently measured. And (b) data related to results of measurements performed at the stage (a) is saved only in case when specified results of measurements are not within the range of values, which have previously been detected as desirable for results of specified parametres measurement.

EFFECT: invention provides for the possibility to track mode of operation in several power transformers located in different substations.
