This
blog provides commentary on high voltage switching power supply demands.
What
is the difference between low, medium, and high voltage? This is an important
question in the age of microelectronics.
A
voltage transformer, also known as a potential transformer, is a device that
reduces voltage. It takes the voltage from a higher level to the safer,
acceptable one. It’s connected parallelly, as a transformer, presenting the
negligible load to the supply.
These
voltage transformers have an accurate voltage ratio as well as a phase
relationship, enabling accurate secondary connecting metering.
There
are three types:
●
High voltage
●
Extra high voltage
●
Ultra-high voltage
High voltage switching power supply
needs
to be controlled remotely (and/or manually). Options include high voltage
windings, high voltage isolations, or both.
Some
industries have high power demands. They usually use medium supply voltage.
Remember that voltage is inversely proportional to amperage. In other words,
when one goes up, the other goes down.
There
is a larger need for power than with a low voltage transformer.
Also
on the menu are low voltage, high current DC power
supply transformers which have a rectifier to convert output into RFI
(radio frequency interference) and direct current. Here, the electricity is
converted while going from one current to the next via a set of windings.
According
to the American National Standard Institute (ANSI), high voltage transformers
can handle of a minimum of 115,000 watts. On the max side, it’s 11,000,000
volts. Medium voltage handles 2,400 to 69,000 volts. Low ranges from 240 to 600
volts.
