On November 9, 1965, a major power blackout left eight states on the North American East Coast paralyzed for thirteen hours, with more than 35 million people in the dark.
For the first time in its history, the United States was experiencing a gigantic electrical blackout that would also affect two states in Canada.
Added to this problem of obscurity were problems in air traffic, in the media, in underground networks; in general, many cities such as New York City collapsed. Thousands of people were held prisoner for hours in elevators and trains that stopped.
One of the most notorious explanations for this topic was that the error was due to a collapse in the grid due to a 375,000 volt overload connecting Canada to the northeastern coast of the USA.
This blackout was the first we know of many that the United States of America had to deal with.
This made it very clear that the participation of products such as UPS and electrical supply equipment are indispensable in the economic and social life of a country in motion, because even if an electrical grid seemed stable, it would never be compared to the reliability that uninterruptible power supplies (UPS for its acronym in English) could offer because it really is their purpose to exist.
TYPES OF ELECTRIC CURRENT
There are 2 types of electrical energy:
La Alternating Current (AC): It has a voltage that changes its polarity every half cycle, following a sine wave shape and its current alternates in direction every half cycle.
La Direct Current (DC): It has a voltage with a fixed polarity and the current always circulates in the same direction.
Alternating Current is found in electrical supply networks and when connected to the UPS it is converted into Direct Current through a rectifier. This energy will be stored in the UPS through its batteries and will be used when a blackout occurs so that mission-critical or more important equipment does not turn off.
Inside the UPS is the inverter, whose function is to convert the Direct Current of the batteries into Alternating Current to power the equipment to be backed up.
WHAT ARE THE MISSION CRITICAL LOCATIONS?
The following examples are some of the elements that can never do without electricity or experience a blackout because it would be lethal to their activity.
The UPS has a backup time of 10 minutes at full load. This means that you have these minutes to save the information, stop a process or start the operation of a Emergency plant. The UPS is the most complete line conditioner because in addition to supporting equipment to prevent a loss of information or process, it provides you with clean and stable energy, which will not give you problems with voltage surges.
