| Abstract | : | In this paper, the principles and structure of the device for measuring phase angle of the power system are presented. Efficiency of the device is explained by an experimental result which is a synchronizing phenomenon oC a synchronous generator on parallel operation. This measuring device has the following features;
(1) Influence of noise can be decreased, because this device is constructed by digital circuit except for input part.
(2) Accuracy of the measurement is easily improved by only changing frequency of the oscillator.
(3) Digital output system is employed to keep the accuracy of measured values. |
