| Abstract: | The temperature feature of the crystal BGO which acts as a sensing element of the electric optical voltage transducer is stu died. Both theoretical and experimental results show that the influence of temperature on the crystal BGO decreases greatly with double light channels compensation. The software compensation method may be applied too. An EVOT through deliberative design can fully meet the service requirements. |
