The Research On Electrical Source About High Electric Potential Of Active Optical Current Transducers

The prerequisite of power system security ,steady ,economy is exactly depend on the measurement of power system parameter ,In it ,the measurement of current is the base to the measurement of electric power and the electric quantity 。Original electromagnetic current transducers a lot of respect being living can not meet the measurement accuracy demand 。In contrast with traditional electromagnetic current transducers, optical current transducers is the substitution。By now , there is still no record in the world to be used in trade operation at the moment 。The stability of power source to the active optical current transducers is always the significant problem。A kind of fresh design was put forward that the parallel connected capacitor plus at 110kV's power system line, supply the current to original edge of the transformer ,Again pair edge by means of the transformer , the steady voltage is the power source of the active optical current transducers,I have taken a conclusion that by prove the power source in Beijing district and Bao ding district time and again that it is effectual to demonstrate this kind of means 。...
