PD DETECTION EQUIPMENT WITH AUTO SIGNAL SELECTOR AND ALARM FUNCTION

摘要

PURPOSE: A partial discharge detecting device with an automatic switching function and an alarm function by partial discharge signals is provided to improve reliability by preventing malfunction due to external noise. CONSTITUTION: An IO device input terminal(26) receives sensing signals outputted from a partial discharge detection sensor(2) and transmits the sensing signals to the inside of a partial discharge detecting device. An automatic/manual switching unit is applied with the sensing signals which are transmitted in the partial discharge detecting device through an input terminal. A partial discharge detector is applied with the sensing signals from the automatic/manual switching unit and detects partial discharge signals. An IO equipment output terminal(24) receives data corresponding to the detected partial discharge signals. A display unit receives the data corresponding to the partial discharge signals detected by the partial discharge detector and displays maximum value, instantaneous value, and visual alarm.
