Annex E22 Power Planning Flashcards
Two (2) types of output phases used in tactical generators
Single Phase 120 Volts
Three Phase 208 Volts
Equation for converting between volt-amperes and watts when operating a tactical generator
True Power (watts)= Apparent Power (volt-amperes) X Power Factor
Benefits of using 3 phase generators
More economical
Better redundancy
Most common method used by electric power distribution grids worldwide
