There may be a reason why some types of electronic transformers supplying 12 volt lamps fail sooner than expected.
Has anyone made any observations as to whether there are less failures where there is only one transformer compared to where there are two or more transfomers on the same circuit.
Reason for asking is as follows.
Some electronic transformers chop the incoming mains supply ON and OFF at a high frequency ( around 40,000 time per second ) as part of the process of creating a 12 volt output from the 230 volt input. This can cause significant high frequency voltage fluctuations on the supply if the transformer does not have adequate filtering.
Where there are two or more transformers on the same supply the high frequency fluctuations generated by each transformer may be dis-rupting the operation of the other transformers. This could cause the "transformer" action to become in-efficient resulting in excessive heating and / or electronic stress on components.
