    摘要: A digital protection relay is provided. An amplification factor is differently applied such that loss of a quantity of light with respect to an input signal is compensated for according to a length of an optical fiber cable for a point sensor. Thus, an occurrence of an arc can be more accurately detected, whereby power facilities and humans can be optimally protected from an arc accident.

    摘要: Disclosed are a relay and method for protecting a transformer, and a transformer protecting system having the same. In the present disclosure, whether a transformation ratio of a transformer has been correctly set or not may be determined based on an inner algorithm. If it is determined that the transformation ratio of the transformer has been incorrectly set, a user may be informed to reset the transformation ratio. This may prevent a malfunction of the relay when the system is operated, and may enhance a system stability.
