OIL FILL/LEVEL CHECK (HT TANK)

The insulating oil level in the HT transformer does NOT require periodic checking under normal conditions.
However, if there is evidence of possible oil loss, the procedure for checking the correct oil level follows. Refer
to 6.4.1 for Millenia generators, and to 6.4.2 for Indico 100 generators.
6.4.1

Millenia Oil Fill/Level Check

1. Using a suitable wrench, remove the oil fill cap on top of the HT transformer.
2. Measure the oil level from the TOP surface of the oil fill flange using a clean ruler. The oil level should
be in the range of 7/8" (22 mm) to 1 3/8" (35 mm) from the top of the flange. Add oil if the oil level is
low, that is greater than 1 3/8" (35 mm) from the top.
3. Use only fresh oil, type Shell DIALA AX or equivalent. Take care not to damage delicate components
inside the tank if using a funnel for oil fill.
4. Replace the oil filler cap and tighten when finished. Wipe up any oil spills. Dispose of soiled absorber in
compliance with government requirements and ensure conformity to local disposal regulations.
