【 摘 要 】

The demand for accurate time synchronisation available 24/7 increases with the growth of critical substation applications, such as phasor measurement, merging units, travelling-wave fault location and current differential protection schemes. In order to yield the best accuracy and granularity from such applications, the use of a common, reliable and precision-time reference is essential.
