1.2 Classification of Multi-Voltage Output Generator Sets
a. Lower power demands can be managed using a universal transfer switch, which supports switching between 3 different voltages.
b. Facilities with qualified on-site electrical maintenance personnel can choose manual modification by adjusting copper busbar connections, supporting switching between 3 different voltages.
c. An optional dual power switch configuration enables automatic voltage switching by adjusting the generator winding connections, supporting switching between 2 different voltages.

1.3 Configuration of Multi-Voltage Generator Sets

A. Universal conversion manual switching mode: main circuit breaker for the generator set (rated current calculated from the minimum voltage segment and lowest number of phases), universal transfer switch, cabling connecting the main circuit breaker to the universal transfer switch and the switch to the generator, multi-voltage control system protection features, and AVR wiring adjustment.

B. Manual copper busbar reconfiguration mode: main circuit breaker for the generator set (rated current calculated according to the minimum voltage segment and lowest phase count), multi-voltage switching insulation boards, cabling connecting the main breaker to the insulation board and the board to the generator, multi-voltage control system protection, and AVR wiring adjustment.

C. Dual power switching winding reconnection method: main circuit breaker for the generator set (rated current calculated according to the minimum voltage segment and lowest phase count), 2 dual power switches and associated control components, cabling between the main circuit breaker, dual power switches, and generator, multi-voltage control system protection, and AVR wiring adjustment.

1.4 Alternator Selection Requirements for Multi-Voltage Generator Sets

The working principle of multi-voltage switching: Based on reconfigurable 12-wire generator windings and standard alternator wiring schematics, the system outputs: 1. Series star winding output: 380V-415V/50Hz and 380V-480V/60Hz; 2. Parallel star winding output: 190V-208V/50Hz and 190V-240V/60Hz; 3. Double delta winding output: 220V-240V/50Hz and 220V-240V/60Hz.

Alternator selection criteria for multi-voltage generator sets:

1. The generator set winding requires a 12-wire output; 2. The AVR must support voltage trimmer potentiometer signal output.

1.5 Market application scenarios of multi-voltage generator sets. Primary market applications for multi-voltage generator sets include: 1. Generator set rental market;

2. Applications where user terminal equipment requires diverse power input voltages;

3. Operations where user terminal equipment uses single-phase and three-phase loads, but not at the same time;

4. Applications across different countries where local power grid output voltages vary.
