Abstract
A device may include a switch having a first position in which the switch connects a voltage source to the conductor segment and a second position in which the conductor segment is connected to operational electronics. A device may include a switch controller configured to change the switch between the first position and the second position. A device may include a current sensor configured to detect a leakage current from the conductor segment when the switch controller causes the switch to be in the first position.
Claims30
A device for determining an insulation integrity of a conductor segment, the device comprising:
- a switch having a test position in which the switch connects a voltage source to the conductor segment and an operational position in which the conductor segment is connected to operational electronics;
- a current limiting component configured to limit a current provided by the voltage source to the conductor segment to a maximum current;
- a current sensor positioned between the voltage source and the operational electronics configured to compare a leakage current from the conductor segment to a current threshold when the switch is in the test position;
- and
- a switch controller configured to:
- upon receiving an activation indication, actuate the switch from the operational position to the test position, and
- upon determining that the leakage current is greater than the current threshold, initiate a fault action.
A method for determining an insulation integrity of a conductor segment, the method comprising:
- transmitting an activation indication to a switch controller;
- upon receiving the activation indication, actuating a switch to a test position connecting the conductor segment to a voltage source via the switch controller, the switch further including an operational position connecting the conductor segment to operational electronics;
- limiting current provided by the voltage source to the conductor segment to maximum current via a current limiting component;
- comparing a leakage current from the conductor segment to a current threshold when the switch is in the test position using a current sensor positioned between the voltage source and the operational electronics;
- and
- upon determining that the leakage current is greater than the current threshold, initiating a fault action.
