3.10 Oil Tray
The oil tray collects oil which can leak from the transformer under fault conditions. The oil separators integrated in the
oil tray prevent the collected oil from leaking out of the oil tray in case the oil tray is full of rain water. The rain water is
heavier than the oil and runs through the oil separator whereas the oil remains in the oil tray.
An oil drain valve must be mounted at the oil tray in order to remove oil that has leaked into the oil tray. In order to
facilitate maintenance work, an inspection shaft must be planned at the oil drain valve.
The oil tray must be secured against floating away.
