The structure,the linking method and the working principle of the automatic measurement system for semiconductor photovoltage spectrum have been reported.
Due to dopant migration, build-in electric field exists in the device.There is open-circuit photoresponse, the detector can operate in photovoltaic mode.
In this paper,the operation margin of mho relays(zone 3 impedance relays) is equivalently redefined as function of bus voltages instead of line impedance.
The diagnosis principle and diagnosability conditions are proposed, and the normal tolerance network test nede voltage interval are given by interval iterative algorithm.
Lower vcore voltage result in instability, then we decided to try to decrease the voltage FSB termination voltage and NB vCore, after obtaining in this case an unexpected results.
