Fail-safe system and test module, notably for use in a railroad signaling system |
| abstract |
A fail- safe system, notably for use in a railroad signaling system, comprising a test module with a photovoltaic coupler able to charge a capacitor. The energy stored in the capacitor provides power supply to a circuit under test. Advantageously, means of measuring a state of charge of the capacitor make it possible to quantify current leaks from the circuit under test. |
