EFFICIENCY LEVELS
DATA NECESSARY TO ESTIMATE EFFICIENCY LEVEL:
 Rated
value of no load and load losses
 Yearly Load profiles specified by:
– Yearly peak load
– Running time
– Loss time
EFFICIENCY
COMMON VALUES OF LOAD PROFILE COOFFICIENTS IN POLAND
Yearly peak load...............0,30....0,35
 Running time..................3500....4560 h
 Loss time........................2100....3100 h
