    摘要: A fiber Bragg grating (FBG) based sensor is used as a strain sensing element to determine frame foot loading of a generator. Three FBGs may be used in tandem to form a basic Frame Foot Loading Module (FFL Module). Two modules are fixed on each vertical support gusset at the corner of the generator frame, with one module on the front of the gusset and a second module on the back of the gusset. Thus, each gusset may be instrumented with six FBG strain gauges or sensors. The gussets are chosen on each of the four corners of the generator. For two-pole generators the first three gussets at each corner may be used and, for four-pole generators the first four gussets may be used.
