The utility side has found that vaporising short circuits is a useful feature, as that includes e.g. twigs hitting a power line. There are breakers, of course, but they react slowly enough that there will absolutely be a massive overdraw first. Then the breaker will open. Then, some small number of seconds later, it will automatically close. It will attempt this two to four times before locking out, in case it just needs multiple bursts. It’s called “burning clear”, and it looks just as scary as you’d think… but it does work. So, solar suppliers need to also survive this. | ||
