Diesel Generator Tech

When the ground fault occurs to the generator in the diesel generator set configuration, it is characterized by loud noise, irregular jitter, temperature rise, unstable voltage, and similar excessive load. This fault is a ground fault caused by insulation damage between the generator winding and the iron core or the casing, also known as a winding ground fault. So, how should our users troubleshoot generator grounding faults? Here, Dingbo Power will share the following content with everyone for learning and reference in   genset maintenance . Ground fault phenomenon The diesel generator set can not operate normally due to the electrification of the generator housing, control line out of control, and winding short circuit heating. Cause of malfunction Due to dampness in the generator winding, the insulation resistance decreases; Long term overload operation of the generator; Harmful gas corrosion; Metal foreign objects invading the inside of the winding damage the insulation; Insula...
