Power transformer monitoring system

  • Continuous monitoring of many diagnostic quantities (voltage vector diagram, energy balance, overvoltage, tg delta of bushings, PD activity) of large power transformer recorded and evaluated by measuring computer with continuous transfer of output data to distant terminal.


  • Two diagnostic monitoring systems more than 10 years in operation. The first one on the block transformer 400/15 kV in Nuclear Power Plant Dukovany, the second on the station autotransformer 400/110 kV in substation Reporyje.
