Transformers troubleshooting

Nov 08, 2016

When the transformer winding when a short circuit occurs, the phenomenon is the transformer temperature is too high, burning smell, the smoke, reduced output voltage, output voltage instability. If these phenomena are found, you should immediately cut off the power supply, check. Main reasons causing short circuit: transformer affected with damp inside a musty, so time will make insulation damage, resulting in serious leakage or short; or insulation of transformer insulation aging time, decrease caused by insulation breakdown, causing short circuits. Sudden increase in supply voltage may cause insulation breakdown, winding short circuit.
