Preliminary
10.1 Bushing Overall test
The following picture illustrates the measurement setup for overall test of a bushing. In this method
the insulation between centre conductor and ground which includes both C1 and C2 can be
measured. Please note that this test is useful if the bushing under test is isolated and not installed
on an equipment such as transformer; otherwise all insulations between centre conductor and
ground would be included in measurement values. This method can be used for all various type of
bushings including condenser types with or without tap electrode and also non-condenser types.
For this test the GSTg A+B mode should be selected.
