A: The relationship between the short-circuit current flowing through the protection device and the action time is called the delay characteristic of the protection device. The delay characteristics are further divided into a definite time delay characteristic and an inverse time delay characteristic. The action time of the definite time delay is fixed regardless of the magnitude of the short circuit current. The inverse time delay action time is related to the magnitude of the short circuit current, the short circuit current is large, the operation time is short, the short circuit current is small, and the operation time is long. The short-circuit current has a certain curve relationship with the action time limit. |
