  "textContent": "Method and system are provided to calibrate detection of condition(s) on an electrical system with a source circuit. The method and system involve measuring using a sensor reference voltages across the source circuit to be supplied downstream in the open circuit state at a first system voltage for calibration; and measuring using the sensor a voltage in the open circuit state when a second system voltage is applied to the source circuit. The method and system further scales a reference voltage from the reference voltages according to a ratio between first and second system voltages; calculates a difference between the scaled reference voltage and a current voltage measured by the sensor; calculates a voltage change over time between prior and current voltages; compares the difference and the voltage change over time to respective thresholds; and in response to the comparison, determines whether a condition on the electrical system has occurred.",
