Set the power supply voltage of the energy storage motor to 236–264 V. Fault 3: Place a hard object at the transmission gear to simulate the situation when the transmission gear is jammed.
The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the …

Rather than viewing end-of-life energy storage systems as obsolete, a circular economy mindset encourages exploring second-life applications. Batteries that no longer meet the demands of utility-scale storage can find new life in less demanding applications, such as stationary energy storage for homes or businesses.
Energy storage can be used to fill gaps when energy production systems of a variable or cyclical nature such as renewable energy sources are offline.
