Abstract
The present disclosure relates to a system and apparatus for monitoring a partial discharge in a switchboard, including a plurality of partial discharge sensors provided in each of a plurality of switchboards to acquire partial discharge data generated in at least one switchboard, and a noise sensor provided in any one of the plurality of switchboards to acquire noise data to be differentiated from the partial discharge data acquired from the at least one partial discharge sensor, and it can be applied to other exemplary embodiments.
Claims7
A system for monitoring a partial discharge, comprising:
- a plurality of groups, each group including a plurality of switchboards, each switchboard including a partial discharge sensor and one switchboard in each group including a single noise sensor for that group;
- and
- a control device, wherein:
- each partial discharge sensor acquires partial discharge data generated in a corresponding switchboard, and transmits the partial discharge data to the control device;
- and
- the single noise sensor for each group acquires noise data for that group and transmits the noise data for that group to the control device;
- and
- the control device monitors the partial discharge based on a result value obtained by differentiating the partial discharge data received from partial discharge sensors associated with a given group of the plurality of groups against the noise data received from the single noise sensor associated with the given group.
An apparatus for monitoring a partial discharge, configured to:
- set a plurality of switchboards into a plurality of groups that each include a subset of the plurality of switchboards, wherein each switchboard of the plurality of switchboards is provided a corresponding partial discharge sensor from a plurality of discharge sensors, and wherein each group of the plurality of groups is set such a single noise sensor is included in that group that is included in a given one switchboard set within that group;
- receive partial discharge data acquired from the plurality of partial discharge sensors provided in the plurality of switchboards, and noise data acquired from the single noise sensor provided in the given one switchboard associated with each group of the plurality of groups;
- and
- monitor a partial discharge based on a result value obtained by differentiating the noise data from the partial discharge data.
