7.8.13 Monitoring the oil pressure (on-load tap-changer)
When you record the oil pressure of the on-load tap-changer, you can use
the pressure relief device (PRD) to 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 oil pressure is greater than the limit value > or
>>, the device triggers an event message.
