Safety Product description
Safety instructions
Make sure that any person installing, taking into operation
and operating the self-dehydrating breather:
• is technically qualified and competent
• fully complies with these assembling instructions
Improper operations or misuse could cause danger to:
• life and limb
• the equipment and other assets of the operator
• the equipment proper function
Safety instructions in this manual are shown in three
different forms to emphasize important information.
Safety notes on the equipment operation
Electrical installation is subject to the relevant national
safety rules.
It is mandatory to connect the grounding cable.
This information indicates particular danger to life and health.
Disregarding such a warning can lead to serious or fatal injury.
It is important to observe the limit values indicated on
the nameplate and in the operating instruction before
commissioning the device.
All relevant fire protection regulation must be strictly observed.
This information indicates particular danger to equipment or
other property of the user. Serious or fatal injury cannot be
excluded.
Installation, electrical connection and fitting the device may only
be performed by qualified personnel and only in accordance
with this instruction manual. It is the responsibility of the user
to ensure that the device is used for specified application only.
For safety reasons, please avoid any unauthorized and improper
usage.
During the regeneration phase, the surface temperature
increases. Touching the surface is dangerous.
This notes give important or specific information concerning the
equipment or as to work with the equipment.

CAUTION
CAUTION
CAUTION
NOTE
The dehydrating breather is used for oil-insulated tran-
sformer and on-load tap-changer to dry the air which is
suctioned in by the oil conservator during the thermal
contraction of the oil mass.
During the normal operation the oil conservator intakes
air that passes through the metallic filter (Fig.5-11/A). The
metallic filter stops dust, sand and other particles from
the contaminating air. The air then passes through the
tank 1 (Fig.16-17-18/1). The salt tank is filled with silica
gel that absorbs the moisture.
When the silica gel absorbs the moisture, the weight of the
salt increases and is constantly monitored by a weighing
cell. When the weight increases and exceeds the pre-set
value a solenoid valve blocks the passage of air through
salt tank 1 and deviates through the “plenum chamber” 2
(Fig. 16-17-18/2)(for eSDB10 it deviates the air through
the main self-dehydrating breather eSDB-15, eSDB-30). At
the same time, a heating system inside tank 1 is activated.
The water vapor leaving the silica gel is expelled outward
by a fan that also dissipates the heat.
Inside the tank, a probe controls the temperature of the
heating element.
After the silica gel regeneration in tank 1, the solenoid
valve is de-energized and the airflow through tank 2 is
inhibited. The salt in this tank (2) is also dehydrated,
regeneration of the salt in tank 2 follows automatically
(not for eSDB-10).
No maintenance is required for replacement and
regeneration of the desiccant.

Operation and
maintenance
Maintenance
During regular maintenance on the transformer, we recom-
mend performing the following checks on the dehydrating
breather:
• Check the exterior condition of the device (especially the
lter air Fig 5-11/A)
• Check the failure contact
• Check the upper level (Fig 16-17-18/E), the internal
bubble must be inside the smallest black ring
• To perform a functional test, follow instructions in
Appendix C.
Movement, transport and storage
Move the eSDB15/30 using the eyebolts in the upper part

vide the information from the shipping list and the serial
number of the Self-dehydrating breather.
During the transformer transport, we advise to disassemble the
air breather and to place it inside the original box.
Not to paint the device. In this case any guarantees concerning
the corrosion resistance decline.
Only mild soap and water should be used to clean the electrical
box cover. Solvents must not be used for any reason as they will
degrade the performance of the paint. Use of solvents on the
unit will immediately void the warranty.
CAUTION
COMEM advices to disconnect eSDB during the electrical
transformer routine test.
NOTE
The total regeneration phase takes about 20 hours.
To abort the regeneration cycle, follow instructions in Appendix E.

NOTA
L' essiccatore è utilizzato nei trasformatori in olio e per
il commutatore sottocarico al ne di essiccare l'aria in
ingresso nel conservatore a seguito delle dilatazioni
termiche dell'olio.
Durante il normale funzionamento, l'aria giunge al
conservatore passando per il filtro metallico (Fig.5-11/A).
Tale filtro ferma povere, sporco ed altre eventuali particelle
contenute nell'aria. Dopo il filtro metallico, l'aria passa
attraverso il serbatoio 1 (Fig.16-17-18/1). Nel serbatoio è
presente il gel di silice che assorbe l'umidità.
Quando il silica gel assorbe l'umidità, il suo peso aumenta
ed è constantemente monitorato dalla cella di carico.
Quando il peso del gel di silice raggiuge la soglia prevista,
l'elettrovalvola blocca il passaggio dell'aria attraverso
il serbatoio 1 e la devia al serbatoio 2 (Fig. 16-17-18/2)
(per eSDB10 l'aria viene deviata all'essicatore principale
eSDB15, eSDB30). Contestualmente viene attivato il
ciclo di rigenerazione all'interno del serbatoio 1. L'umidità
evapora dal gel di silice tramite l'utilizzo di un ventilatore
che aiuta anche a dissipare il calore.
All'interno dei serbatoi, la temperatura viene monitorata
tramite l'impiego di apposite sonde.
Dopo la rigenerazione del serbatoio 1, l'elettrovalvola
viene disattivata ed il flusso d'aria attraverso il serbatoio
2 viene inibito. Il gel di silice contenuto nel serbatoio 2
viene essiccato automaticamenet dopo il completamento
della rigenerazione del serbatoio 1 (non applicabile per
eSDB10). Non è richiesta alcuna manutenzione per la
sostituzione o rigenerazione dell gel di silice.
