| Abstract: | A high voltage switchgear key points on line monitoring system is designed,which demodulated by a volume phase holographic diffraction grating,employing fiber Bragg grating as temperature sensor.In order to test the temperature characteristics of polyimide materials packaged FBG,some experiments are carried out.The good linear relationship between FBG wavelength and temperature is verified.A good test results is gotten,when the system is applied in the field. |
