摘要： A ground fault protection system includes a power switch including a source-side and a load-side. The power switch is structured to receive a load current from a power source at the source-side and selectively output the load current from the load-side to a load. A first voltage measuring device is structured to measure a first voltage of the source-side while the power switch is not conducting the load current. A second voltage measuring device is structured to measure a second voltage of the load-side while the power switch is not conducting the load current. A controller is structured to determine a source-side-to-ground voltage based on the first voltage, determine a load-side-to-ground voltage based on the second voltage, determine a ground fault is occurring, and determine a direction of the ground fault relative to the power switch.

摘要： The present invention provides a discharge handling system capable of appropriately handling occurrence of an arc discharge according to a situation. A discharge handling system includes: a power module; a power conversion device; and an arc discharge detection device, the arc discharge detection device including an arc discharge detector configured to detect occurrence of an arc discharge between the power module and the power conversion device, the arc discharge detection device monitoring the number of times of the arc discharge detected by the arc discharge detector and discharge time of the arc discharge every time a monitoring time elapses. The discharge handling system includes a determination unit configured to determine necessity of maintenance within a predetermined period on condition that any of conditions (1) to (3) below is satisfied: (1) the number of times of the arc discharge in the monitoring time is from 1 to a number-of-times threshold inclusive; (2) each of the discharge time of the arc discharge in the monitoring time is equal to first determination time or less; and (3) total of the discharge time of the arc discharge in the monitoring time is equal to second determination time or less.

摘要： A current leakage detection circuit (10) that detects current leakage from a battery having a first electrode and a second electrode, which is either the positive electrode or the negative electrode opposite to the first electrode, to a chassis includes: a detection circuit (5a) including a reference voltage source terminal (VR), a first detection terminal (In1), and a ground terminal (GND) connected to the first electrode; a first resistor (21) (or (28)) connected between the second electrode and the chassis; a second resistor (22) (or (27)) connected between the chassis and the first detection terminal (In1); and a third resistor (23) (or (26)) connected between the first detection terminal (In1) and a predetermined terminal. When the first electrode is the positive electrode, the predetermined terminal is the reference voltage source terminal (VR). When the first electrode is the negative electrode, the predetermined terminal is the first electrode. The detection circuit (5a) detects an occurrence of current leakage based on a voltage of the first detection terminal (In1).
