变压器式相序监测和保护装置

A Transformer-type Device for phase-sequence Monitoring and Protecting

采用新颖的双感式相序传感器,可方便地实现相序的显示、声报警及保护,完善了供电装置的功能,提高了工作稳定可靠程度。

To realise phase-sequence display,audible alarm and protection,a new double-induction phase- sequence sensor is developed.The function and reliability of power setting is thus improved.
