Benefits and applications of medium voltage according to Marvin M, one of the member of the community.


Traditionally, any voltage over 600 V would evoke thoughts of high danger from the perceived high voltage. Engineers and technicians alike would abandon any systems operating over that limit and instead focus on the low voltage components, citing relative low risk levels.

Today, however, high skill levels, standards and installation requirements ensure that working with medium voltage is safe. It accords the following benefits.

Circuit Breakers explained on a series of tutorials. That’s what Nasir, one of the member of the community decided to do. Here’s the 6th part, we hope that you enjoy his contributions.

Medium voltage circuit breakers are the ones which operate on voltage levels around 400 volts to 15kV approximately. The reason they are named so is that extremely low voltage conditions are not suitable for them to operate properly, neither a very high voltage helps them perform their operation accurately. So a medium voltage level around this figure is normal for them to operate on.

One thing that is different about the medium voltage circuit breakers is that unlike most of the types of these breakers, they can be operated manually as well. The reason behind this manual operation is that since they can also operate on voltage levels below 600 volts, and this thing gives them the incentive to be manually operated.

It should be kept here in mind that only the circuit breakers which can be operated on voltages lower than 600 volts can be manually operated.
