Put an Indicator lamp on one phase of single phase no nuetral
Put an Indicator lamp on one phase of single phase no nuetral
(OP)
I wish to put an indicator lamp on one phase of a three phase supply inside a transformer rectifier. There is no nuetral. The primary of the transformer in wired in Delta so no nuetral there. Other than wiring to the earth (which I would have thought is not recommended) or installing a secondary piece of equipment is there any way of putting a indicator lamp on one of the phases?

You could connect a lamp phase to phase. If one with a suitable voltage can be found. Or you could create a something close to a neutral with a suitable selection of capacitors to divide and phase shift the three phase voltages.
