2– INSTALLATION (BREATHING TRANSFORMERS WITH
CONSERVATOR)
2.1 Preamble
The following installation procedure is given for information only. Automation 2000
cannot be held responsible for its execution.
2.2 Installation precautions
Before installing the DGPT2-IB, make sure that:
The transformer is not powered.
The transformer dielectric is at ambient temperature (approx. 20°C).
The transformer conservator is empty.
The dielectric level inside the transformer is slightly below the transformer
tank cover.
The transformer opening on which the DGPT2-IB will be installed is opened.
2.3 Installation procedure
Fit the FPM seal (supplied) in the DGPT2-IB attachment flange throat.
Mount the DGPT2-IB on the transformer opening designed for that purpose.
Attach the fixing hooks (supplied) on the fixing bolts (3 at 120° or
4 at 90°) according to the tightening precautions (see page 4). The fixing bolts
must be located on a circle with a 97 mm diameter (±2 mm).
Connect the DGPT2-IB to the conservator through its IB insert with a flexible
tube equipped with both a 3/8” female threaded end and a rotary fitting.
Fill the conservator up to its normal level.
Slowly open the DGPT2-IB sampling tap until the transformer dielectric level
reaches the DGPT2-IB highest point and close it.
