摘要：

We developed a new optical voltage transformer for power protection relays in HV transmission lines. Two temperature compensation approaches, namely, the temperature controller-box method and the dual-optical-path method are discussed and adopted in the apparatus. In addition, the retard of the circuit has been analyzed by experiments. A large number of experiments proved the correctness of our design. (C) 2002 Published by Elsevier Science B.V.
