Consistent power supply is essential for most major
establishments that are now dependent on the electric supply for the
powering of major devices and security mechanisms. Often major
establishments like the hospitals, banks, data centers, big corporate
offices, prisons, and IT hubs put in high-power generators in place to
ensure there is a consistent supply of electricity even under conditions
of mechanical failures or power shortage. The establishments might have
either new or used generators in place; however, the efficiency of
these devices depends on the power transfer mechanism, which is the main
function for these devices.
The power transfer mechanism is vastly depending on
the type of load transfer switches that have been installed with your
system. Many establishments continue to ponder over the pros and cons of
the two main types of load transfer switches – Manual and automatic.
While the manual switches need to be triggered by a personnel of the
establishment, the Automatic Transfer Switch
is triggered seamlessly at any indication of blackouts. Here is a look
at the three major pros and cons of the automatic versions of load
transfer switches.
Advantages of Automatic transfer switches
• The biggest advantage of automatic power transfer
switch is that it can automatically transfer the load of the power on to
the generator. This makes the transition from main power supply to the
generator seamless and the establishment does not lose even a minute of
time in the power break.
• The second advantage of an automatic changeover
switch s that it has built in sensors to detect any fluctuations in the
voltage and frequency of the main power supply. These sensors have an
optimum set mark and if the power goes below his mark, the generator
will automatically trigger on. If there is a power trip at any one part
of the establishment, the generators will handle the shortage of power
created due to that issue.
• The final advantage of the switches is that they
have a time delay mechanism, which strives to protect both the generator
device and your electric circuits from the fluctuations in power. The
time delay strikes at between 0-5 seconds during the beginning of the
power transfer from main to generator. The end of the transfer session
has a time delay of 1- 30 minutes where the generator normalizes
according to the main power supply before the full transfer of circuits
is made on to the main.
Disadvantages of the automatic power switches
• The major disadvantage of the automatic transfer
switches is that there is a higher margin of error for many
establishments. There can be discrepancies in choosing the appropriate
power of switch to support the number of generators an establishment has
in place. This often leads to the failure of the entire mechanism.
• The second disadvantage is that the automatic switches are a tad bit more expensive than manual switches.
• The automatic switches will also need a more technical and elaborate maintenance routine as compared to the manual switches.
