Oil Level Gauge


This gives a clear visible indication of the oil level in the conservator. It is normal practice to use magnetic oil level gauges with low-level alarm and trip contacts. This can also be of the plain glass or prismatic type. The oil level gauge is marked to indicate minimum, normal and maximum oil levels in the conservator (as a function of conservator capacity). The conservator (or partition) for on-load tap changer carries its own oil level gauge. For bigger units, it is our standard practice to fit a normal oil level gauge on the tank also.
