1. A method comprising:
injecting an electrical signal into an electrical power-transfer system, wherein the electrical power-transfer system comprises an electrical power source, an electrical load, a first sensor, a second sensor, a first conductor, and a second conductor, and wherein the first sensor is electrically coupled to the second sensor and the first conductor, and wherein the second sensor is electrically coupled to the second conductor;
measuring, during or after the injection of the electrical signal, an electrical property between the first sensor and the second sensor to obtain a measurement;
determining that the electrical power-transfer system is in a hazardous state based on the measurement of the electrical property between the first sensor and the second sensor; and
in response to the determining that the electrical power-transfer system is in the hazardous state, performing one or more actions to correct the hazardous state.
