发电机的谐波组开路或短路，无三次谐波电压输出，检查绕组接头或拆换绕组。
If no triple overtone voltage, check the winding lug or replace with another winding.
分别采用白炽灯和日光灯作为光源，测量了太阳能电池的伏安特性、开路电压、短路电流、最大输出功率、填充因子、光照特性等基本特性。
Using fluorescent and incandescent as light source, basic features of solar cells such as short circuit current, open voltage, maximum output filling factor and so on were measured.
分析得到开路故障不会影响系统输出电压，但会明显影响单逆变器模块电感电流和输出电流。
The result is that open circuit fault does not affect output voltage of the system, but it apparently affects inductance current and output current of single module inverter.
