Type 1+2 Surge Protection For Power Supply , Surge Protective
Device
*DC surge protector is an electrical component used to limit
transient over-voltage phenomenon. Because it needs to operate for
a long time, there will be aging. If the DC surge protector is used
for a long time, the aging caused by it will not be timely. If the
facility is updated, it may cause performance degradation, failure
and other malfunctions. Therefore, the DC surge protector needs to
be inspected regularly. If the inspection result shows aging or the
status indicator is invalid, please replace the DC surge protector
in time.
OBV5-B60
The combination lightning current and surge arrestors OBV5-B60 meet
the type 1+2 requirement class according to IEC 61643-11. These
devices protect low-voltage consumer systems from overvoltages of
all types and are available in single-pole to four-pole versions.
The use of high-performance varistors permits a rapid response time
and a low protection level, without any line follow current. If
circumstances are uncertain and there is a risk of fire from an
overload, the internal cut-off unit disconnects the arrestor from
the mains if necessary. In addition, the QR code printed on the
arrestor allows direct access to the online installation
instructions.

Transient voltage surgesin lv power lines
Transient overvoltages are voltage surges that can reach tens
ofkilovolts with a duration of the order of microseconds.Despite
theirshort duration, the high energy content can cause serious
problemsto equipment connected to the line, from premature aging to
destruction, causing disruptions to service and financial
loss.Thistype of surge can have various different causes, including
atmospheric lightning directly striking the external
protection(lightning rods) on a building or transmission line or
the associatedinduction of electromagnetic fields on metallic
conductors.
Outdoor and longer lines are the most exposed to these fields,which
often receive high levels of induction.
It is also common for non-weather phenomena, such as transformer
centre switching or the disconnection of motors orother inductive
loads to cause voltage spikes in adjacent lines.
Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so
limiting the peak voltage to an acceptablevalue for connected
electrical equipment.
A ground connection in adequate condition is, therefore,a key
aspect for effective protection against overvoltages.Monitoring
ground connection condition guaranteesproper operation of surge
protection devices.
