SF6 End-of-life recovery machines for middle voltages

For transformers and shunt reactors, similar failures to withstand recovery voltage may occur. This problem usually is more pronounced for shunt reactor de-energization, where a high frequency, high magnitude transient recovery voltage may result in re-ignitions. Re-ignition transients are also dangerous for system equipment
