How to Identify Damage Failures in Flat Wound Inductors 1

The NDS355AN flat wire vertical winding inductor is a common type of inductor used in current transformers and voltage transformers within power systems. When the flat wire vertical winding inductor is damaged, it may lead to malfunctions and abnormal operation of the power system. Therefore, promptly identifying damage to the flat wire vertical winding inductor is crucial. Below is an introduction on how to identify damage to the flat wire vertical winding inductor.diode,

1. Visual Inspection

1. Inspect the appearance for any obvious physical damage, such as cracks or deformations. Such damage may cause the inductor to lose performance or become completely non-functional.

2. Check whether the connector part is loose or detached. If the connector part is loose or detached, it will result in poor connection of the inductor, thereby affecting the transmission of current or voltage.diode,

2. Insulation Resistance Measurement

Measure the insulation resistance of the inductor using a multimeter or insulation resistance tester. Under normal conditions, the insulation resistance should be very high, typically ranging from several megohms to hundreds of megohms. If the insulation resistance is too low, it may be due to damaged or contaminated insulation material, requiring timely replacement or cleaning.

2. When measuring insulation resistance, pay attention to external interference or grounding to avoid affecting the measurement results.diode,
