Abstract
An optic-electric measurement system for measuring voltage distribution along the HVDC converter valve, consisting of the transmitter, light route arid receiver, is developed. The system operates on pulse frequency modulation of the signal to be measured. Its bandwidth is from DC to 1.2 MHz, its partial response time is 120 ns and its maximum non-linear error is 1%. Experimental results show that this optic-electric measurement system can meet the requirement of measuring voltage distribution of valve with high capability of suppressing electro-magnetic interference and high measurement precision.
