Abstract
A solid state switch module is provided for use in a power distribution network including an input differential protection connection for receiving a measured current value from an upstream module. The solid state switch module also includes an output differential protection connection for sending a measured current value. The solid state switch module includes a trip outlet for sending a trip signal to an upstream solid state switch, and a trip inlet for receiving a trip signal from a downstream solid state switch. The trip inlet is operably coupled to the switch. A current sensor measures the current value of a connected power transmission line across the solid state switch module. A summer adds a current input from a parallel module with the current measures by the current sensor. A comparator determines whether an amount of current lost between the solid state switch module and an upstream module is acceptable.
