DISTRIBUTION OF n RATED POWER YEAR OF MANUFACTURING YEAR OF MANUFACTURING n LOSSES

RATED POWER DISTRIBUTION OF RATED POWER IN ONE OF UTILITIES IN POLAND

RATED POWER DISTRIBUTION OF TRANSFORMERS IN SEVERAL UTILITIES IN POLAND

MANUFACTURING YEAR DISTRIBUTION OF 160 kVA TRANSFORMERS IN ONE OF UTILITIES IN POLAND

MANUFACTURING YEAR DISTRIBUTION OF 400 kVA TRANSFORMERS IN ONE OF UTILITIES IN POLAND

Units with age above 25, 30 and 35 years in groups of transformer rated 160, 250 and 400 kVA.

LOSSES DISTRIBUTION RELATION OF LOSSES IN TRANSFORMERS RATED 160 kVA IN ONE OF UTILITIES IN POLAND

LOSSES DISTRIBUTION RELATION OF LOSSES IN TRANSFORMERS RATED 400 kVA IN ONE OF UTILITIES IN POLAND

LOSSES DISTRIBUTION NO LOAD and LOAD LOSSES OF 160 kVA TRANSFORMERS IN ONE OF UTILITIES IN POLAND

LOSSES DISTRIBUTION NO LOAD and LOAD LOSSES OF 400 kVA TRANSFORMERS IN ONE OF UTILITIES IN POLAND

LOSSES COMPARISON LEVELS OF LOSSES OVER THE YEARS

EFFICIENCY LEVELS DATA NECESSARY TO ESTIMATE EFFICIENCY LEVEL: n Rated value of no load and load losses n Yearly Load profiles specified by: –Yearly peak load –Running time –Loss time
