Application: Applications<br />For Transformers: The internal winding of a transformer often endures unstable voltage for long periods when used under normal conditions. Over time, the insulation is affected if the primary side components are in a state of corona discharge. For example, most power transformers reserve an auxiliary coil for other circuits to use in the primary side as the figure shows. When it is used under Vp=750V for a period of time and if the manufacturing process included faulty insulating tape or tubing it would cause a continuous corona discharge. Insulation of primary winding would be compromised and burned out eventually due to the enameled carbonization.<br />For Motors: As industrial motors or EV motors are used for long hours and under varying environmental conditions such as temperature and humidity, features like high durability and reliability are most critical. Temperature is also one of the key factors to influence insulation. If corona discharge occurs in turn-to-turn and turn-to-ground, it would cause the insulation to deteriorate due to the increase in heat and material qualitative change. Adding Corona Discharge Detection in hipot testing exceeds the quality requirements for insulation by detecting units with poor insulation early thus reducing the defect rate caused by long-term usage. The image shows Corona Discharge in a motor.
