Long cable induction???
Long cable induction???
(OP)
We have a relay that is being activated by an induced voltage (115V) in a long cable application.
The circuit is like this: 230V AC 50Hz source, connected to a long 2G1,5 (1,5 square milimiters) cable (400 meters) connected then to an auxiliary contact, then back to the A1 of the relay, then the relay A2 is connected to neutral. In the installation, the cable is separated from power cables a minimum of 15 centimeters.
When we disconnect from its 230V source, the voltage dissappears.
Then we connect again, but disconnect in the auxiliary contact, well-separating the cables, and the voltage is induced in the same way.
Any hint??
Thanks,
Martin
