7.8.10 Monitoring the gas volume of the Buchholz relay (OLTC)
When you record the gas volume of the Buchholz relay of the on-load tap-
changer, you can set 2 limit values for the gas volume. If the on-load tap-
changer has multiple columns, you can set 2 limit values for each column. If
the measured gas volume is greater than the limit value > or >>, the device
triggers an event message.
