Current Sensor for Monitoring a Wayside Signal Lamp for a Positive Train System |
| 摘要 |
A sensor for monitoring the current flowing in a wire of a circuit is provided. The sensor includes a variable inductance contactless current detector to sense the current flowing in the wire, serially connected to an internal power source and a resistor to form a voltage divider circuit. The sensor also includes a voltage detector to monitor the voltage level across the resistor and generate an output signal. A system is also provided. |
