Find below a new update from Richard Douglas on the debate between high voltage circuit-breaker or fuse !

=========================
I would like to come back to the debate of last year about MV/LV transformer protection using circuit-breakers or fuses.
There were a lot of comments confirming my opinion that circuit-breakers are the best MV/LV transformer protection solution.
However, there were also comments, and that was the debate, that promote fuses as the preferred solution. The main suggested reasons for this are that fuses are: lower in price, have a faster response time for high short-circuit currents, require less maintenance and that it is very simple to understand how they work.
