What is it? Where are they used? How it works?
See this and other important information about this device and where to find it for purchase.
DPS is the acronym for Surge Protection Device, also known as Surge Suppressor and Electrical Surge Protector. These terms are designated to devices capable of protecting electronic equipment against voltage spikes.
These voltage spikes are caused by events such as atmospheric discharges (lightning), switching on and off of nearby devices (mainly in areas that have industries) and large fluctuations coming from the energy distribution network in general.
Power surge protection devices are equipment to detect the presence of transient overvoltages in the electrical network and drain them to the grounding system before they propagate through the network and reach electrical and electronic equipment.
Where are they used?
DPS can be used in various situations such as: in electrical power networks, to protect transformers and urban luminaires, telecommunications lines , photovoltaic energy panels, distribution boards in commercial and residential buildings and even directly in sockets, protecting equipment important. It can be installed at the standard input or in the General Distribution Board (QDG), or in specific parts of the electrical installation, protecting all devices or just one.
How does DPS work ?
On one side, the device is connected to phase/neutral; at the other end, the earth. When there are atmospheric discharges, the device regulates the supplied voltage and absorbs it, draining it to the grounding system. When this energy is beyond its capacity, the device burns, activating the thermal device that turns off the entire electrical network, preventing damage to the equipment.
To check whether this burn has occurred, all protection devices have a status indicator. If it turns red, it is because the circuit is damaged and needs to be replaced. Electrical surge protection devices are essential to protect you from home and corporate power grid problems.
And is there a specific type of DPS for each type of protection?
Try!
There are three DPS classes :
Class I: devices capable of draining partial lightning currents, for peripheral urban and rural areas, which are exposed to direct atmospheric discharges;
Class II: devices that drain induced currents, in buildings, with indirect effects of atmospheric discharge;
Class III: devices installed close to equipment connected to the electrical, data or telephone network, for fine protection.
THS surge protection devices (DPS ) are classified in class II, which would be the models recommended for civil construction. And they are available in the following chains:

Is installing DPS mandatory?
Yes, it is mandatory.
The ABNT 5410/2004 standard, in its item 5.4.2.1, establishes that all buildings within Brazilian territory, which are fully or partially powered by an overhead line, and are located where thunderstorms occur on more than 25 days per year, must be provided with DPS; (External influence zone AQ2). When parts of the installation are located outside the buildings, exposed to direct discharges, (External influence zone AQ3) the DPS is also mandatory.
