| Main difference between HV Generators and LV Generators |
| Features | LV Engine Generation | HV Engine Generation |
| Engine/Motor | World top engine brands like Cummins, Perkins,MAN, MWM, MTU etc. | World top engine brands like Cummins, Perkins, MAN, MWM, MTU etc. |
| Alternator | Low voltage Level; Generally using single bearing | High voltage level; Generally using double bearing |
| Distance of power transmission | Generally for Short distance less than 500m | Generally for Long distance more than 500m |
| Power loss | Big Line Loss in Power Distribution and Transmitting | Small Line Loss in Power Distribution and Transmitting; There is no transmitting-heating problem |
| Investment and operation Cost | Small monetary investment at initial stage; More advantages for low power capacity and short transmission distance; Highly operation cost for large power capacity and long transmission distance. | Big monetary investment at initial stage; More advantages and cost-saving for large power capacity and long transmission distance. |
| Operations & Maintenance | Simple, low requirements for operator’s professionalism | Complicated, high requirements for operator’s professionalism |
| Configuration | Simple, configured with low voltage alternator and low voltage switchgear panel. | Complicated, especially in alternator and outgoing distribution panels, including HV alternator, HV Switchgear panel, PT Panel, Inlet and outgoing panel etc. |
| Safety | High Safety Level; Mature technology; Lower Technological barriers | High Safety Level; Mature technology; Higher Technological barriers |
| Development Tendency | Holding traditional generation market, especially in small power ratings | Growth of generation market in big power ratings |
