Question…
The railways are using hrc fuses in series. They have more than 30 fuses in series connections. If any one of the fuse is blown, they want to know which fuse is blown bcoz manually checking each fuse and detecting the faulty one is time consuming.
My idea…
The given circuit. Before each fuse, we have to make a parallel connection containing a high resistance, relay, led which is grounded. If any of the fuse is blown, the high current passes through the respective parallel circuit & the relay coil is energised. When the relay coil is energised, a closed circuit is formed between relay and LED, and so LED is ON. Thus detection works.
is the circuit a blunder...? suggestions..?
