By using an ultra-wide frequency band partial discharge detecting system
the discharge signal from disk-type spacer in key part of 110 kV GIS(which is used in Yuquan power supply substation) is acquired and studied.It is found that spacers in different parts of GIS have their own partial discharge characteristics
and their discharge frequencies concentrate below 300 MHz
which provide numerical reference for the on-line monitoring of GIS.
