The accumulation of gases in the two these scenarios is an extremely slow procedure but can even now be detected because of the relay. If the specific situation is minor then the alarm goes off. But if the situation aggravates additional, which occurs if the oil enters the connecting pipe involving the key and the conservator tank, the upstream circuit breaker excursions.
