Starlight generator

Some users may not know about voltage transformer of Perkins generator set. Voltage transformer is a special transformer with limited structure and use form.  What causes voltage transformer failure in   Perkins diesel generator set ? 1.Winding turn to turn short circuit Fault phenomenon: During operation, the temperature rises, there is discharge sound, the high-voltage fuse is blown, the secondary side voltmeter indication is unstable. Reason: System over-voltage, long-term overload operation, aging insulation, poor manufacturing process. 2.Insulation damage between iron chips Fault phenomenon: temperature rise during operation. Reason: Poor insulation between iron chips; Poor service environment; Long term operation at high temperature promotes aging of insulation between iron chips. 3.Poor contact between grounding lug and iron core of diesel engine Fault phenomenon: There is discharge sound between iron core and oil tank during operation. Reason: ...

When using a generator, it is inevitable to encounter various problems. What are the common problems? How to solve it? Starlight will list some common generator failure problems and solutions. 1. The generator does not operate according to the specified technical conditions. For example, if the stator voltage is too high, the iron loss increases; if the load current is too large, the stator winding copper loss increases. If the frequency is too low, the cooling fan speed will be slowed down, which will affect the heat dissipation of the  generator . If the power factor is too low, the rotor excitation current will increase and the rotor will heat up. Check that the indication of the monitoring instrument is normal. If it is abnormal, necessary adjustment and treatment shall be carried out to make the   generator   run in accordance with the specified technical conditions. 2. The three-phase load current of the generator is unbalanced, and the overloaded one-pha...
