摘要： A method for a fault ride through testing of an electrical system including one or more power sources, one or more power consumers, and a first protective-isolation device and a second protective-isolation device both disposed between the one or more power sources and the one or more power consumers is disclosed. The method includes prior to the fault ride through testing, opening the second protective-isolation device, and closing the first protective-isolation device, and during the fault ride through testing, opening both the first and second protective-isolation devices to block current flow between the one or more power sources and the one or more power consumers. The method also includes during the fault ride through testing, decreasing a terminal voltage of the one or more power sources using a voltage regulator, and following the fault ride through testing, opening the first protective-isolation device, and closing the second protective-isolation device.

摘要： An apparatus configured to test an electrical system including one or more power supplies, a load, and one or more protective-isolation devices disposed between the one or more power supplies and the load is disclosed. The apparatus has a first measurement assembly configured to sense a first voltage or a first current at an input side of the one or more power supplies, a second measurement assembly configured to sense a second voltage or a second current at an output side of the one or more power supplies, and a third voltage or a third current between the one or more protective-isolation devices and the load, and a power controller electrically disposed between the second or third measurement assembly and a fault assembly. The fault assembly and the power controller are configured to selectively induce a fault, which is selected from a plurality of fault types, either to the output side of the electrical system or between the one or more protective-isolation devices and the load.
