Abstract
A virtual ΔT trip criterion is implemented in an electrical power distribution system to provide current-based tripping for a solid state power switching device. A first-order system model is implemented either by hardware or software to represent a rise in temperature of the electrical wire through which power is supplied. When the simulated temperature exceeds a threshold, the solid state power switching device may be tripped.
