SYNOPSIS:
|
|
|
|
|
WELDING SETS
ARE NOT ON LOAD ALTHOUGH THEY ARE PERMANENTLY
KEPT SWITCHED ON. During the non use period the welding set consumes
power, although at a lower level compared to the power consumed when
welding operation is going on. However the non-use period power is
quite substantial and this Energy can be saved only by switching off
the set manually. Since this is not a practical proposition, the sets
are permanently kept switched on.

|
|
The ENERGY SAVER is
ideal for use with both types viz. Transformer and
Rectifier types to SAVE ENERGY.A contactor is to be provided, if not
already provided to carry out the switching operation.
In the SEMI AUTOMATIC MODEL, the Electronic unit automatically switches
off the set, by cutting off supply to the Contactor, when the welding
set is not in use for the factory preset time interval of about 15
seconds. This time interval can be increased or decreased, if the
requirement is indicated at the time of ordering. TO CONTINUE WELDING,
the set will have to be switched on manually using a micro switch or
reset button provided.

SCOPE FOR SAVING ENERGY:
|
|
|
|
|
In a welding set
of 30 KVA, the no load power consumption is around 1.00 K.W. Generally
in an 8 hr. shift, it is possible to save around 5 units, as the total
non-welding period is likely to be around 60%. The savings per year on
2 shifts basis and 300 working days will be around 3000 units and hence
cost of the system can be RECOVERED IN LESS THAN ONE YEAR. Of course
the saving will be depend upon the capacity of the set, the total non
use period etc.

ADVANTAGES:
|
|
|
|
|
ENERGY SAVING AND
CONSEQUENT REDUCTION IN ELECTRICITY BILL.
REDUCTION IN MAXIMUM DEMAND AND CONSEQUENT REDUCTION IN MAXIMUM DEMAND
CHARGES.
IMPROVED POWER FACTOR OF THE SYSTEM
EXTENDED LIFE OF WELDING SETS DUE TO LOWER HEATING UP OF TRANSFORMER
