Document Type and Number:
Japanese Patent JPH05119853
Kind Code:
A
Abstract:
PURPOSE:To sufficiently execute a regular inspection, and an inquiry into the cause, etc., at the time when an accident and abnormality are generated by constituting the voltage adjustment relay so that the control data of the necessary minimum quantity can be stored in the voltage adjustment relay itself. CONSTITUTION:The voltage adjustment relay 1 is constituted so that a command signal for switching the tap changer of a power transformer 6 is outputted, based on the current data and voltage data of a secondary side of the power transformer 6 to be detected. Also, this voltage adjustment relay 1 is provided with a day counting means 12, a recording day setting means 13 for control data, a storage means 3, and a storage commanding means 2 for storing the current data and the voltage data which are detected, in the storage means 3, when a counted day by the counting means 12 coincides with a set recording day in the recording day setting means 13.
