How to select a TEMCO
Transformer is a rather simple, but important process. It will require
some research and possibly some detective work, depending on your exact
circumstances. If you have existing equipment you will need to expect to do
some leg work observing the specs given on the motors, machines and other
devices. If you have spec sheets on them, all the better. In fact, We
recommend documenting and even copying in some way the tags, labels, etc,
that carry this information so you will have it to hand during this and
other future projects.
The steps to How to
select a TEMCo Transformer begin with knowing all of the following data.
1. The
Primary Voltage (voltage you will be feeding into the primary
windings of the transformer). Essentially, this is the voltage of the
incoming line you will use to power up your installation.
2. The
Secondary Voltage (the voltage you will be operating your equipment
on. For instance, if you are operating 220v motors you will need to have a
secondary voltage of 220v.)
3. The Frequency
(in Hertz) of the service you are using; usually 60Hz in the US and 50 Hz
for foreign applications, but this must be verified as it will affect the
specifications of your transformer.
4. What
Phase is the incoming current? Household is most often single phase
and industrial or shop is often three phase. But this must be confirmed as
it will affect your transformer specs and shops are not all made the same. It is not uncommon for a shop to have started out simple and under-powered
if expectations originally were not to have extensive or heavy equipment
installed.
5. The KVA
load. For this you will need to add the total number of existing equipment
to be serviced by this transformer and one should also add in any possible
future additions to equipment. Here is where your collection of data off
spec sheets and tags or labels will be important as it may be the only place
this information can be found.
6. The
Secondary Voltage. Is it single phase (2 wire or 3 wire) or three
phase (3 wire or 4 wire)? Number 4 above affects the primary circuit of your
transformer; #6 affects the secondary circuit you will need.
7. Type of
Transformer; i.e., double-wound (for electronic
controls, DC equipment or computer applications) or auto-transformer
(for use with motors and other inductive loads.)
8. Where the
Transformer will be installed
(wall or floor and indoors or outside)
How to select a TEMCo
Transformer also includes
additional options you will need to speak with our representative about. Special sprinkler shields, electrostatic shielding, tap arrangements,
vibration dampening pads and others are among these options.
Transformer size can be determined by using the following formulas. This is
where you get to use the data you collected!
Single Phase
Your transformer full load (current in amps)
kVA = Volts x Amps / 1000
Amps = kVA x 1000 / 1.73 x Volts
Three Phase
Your transformer load current per line (current in amps)
kVA = 1.73 x Volts x Amps / 1000
Amps = kVA x 1000 / 1.73 x Volts
