Energy storage inductor failure

What are the dangers of an inductor in an electrical circuit?

An inductor in an electrical circuit can have undesirable consequences if no safety considerations are implemented. Some common hazards related to the energy stored in inductors are as follows: When an inductive circuit is completed, the inductor begins storing energy in its magnetic fields.

What are some common hazards related to the energy stored in inductors?

Some common hazards related to the energy stored in inductors are as follows: When an inductive circuit is completed, the inductor begins storing energy in its magnetic fields. When the same circuit is broken, the energy in the magnetic field is quickly reconverted into electrical energy.

What happens when an excited inductor loses connection to the supply?

When an excited inductor loses connection to the supply, it quickly breaks its magnetic fields and tries to continue the connection to the supply with the converted energy. This energy can cause destructive arcing around the point where the connection is lost. Thus, the connectivity of the circuit must be continuously observed.

Why is an inductor lossless?

In such cases, the current, I, flowing through the inductor keeps rising linearly, as shown in Figure 1 (b). Also, the voltage source supplies the ideal inductor with electrical energy at the rate of p = E *I. Without the internal resistance, the inductor is lossless because it cannot produce heat or light from the available energy.

What are the safety considerations for inductors?

Therefore, considerable mechanical and electrical support should be provided to dissipate any stress or heat produced safely. Another safety consideration is to verify the de-energized state of inductors. Any residual energy in inductors can cause sparks if the leads are abruptly disconnected.

Can inductors cause sparks?

Any residual energy in inductors can cause sparks if the leads are abruptly disconnected. The exponential characteristics of a practical inductor differ from the linear behavior of ideal inductors; both store energy similarly–by building up their magnetic fields.
