Power Surge Protection Device For The Low Voltage Power
Distribution Cabinet/Box
OBV10-I-15
Surge protectors OBV10-I-15 meet the type 1 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
voltage-limiting,high-performance spark gaps provide several
benefits.A short response time, a low protection level and high
current leakage capability with long service life.

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.
Surges in telecom andsignalling networks
Surges tend to induce currents in allmetal conductors; not only are
thepower lines affected, but so are allcables to a greater or
lesser extent,depending on the distance to the focusof the surge.
Although a lower current is induced,the effect produced is equally
or moredestructive, due to the greatersensitivity of electronic
equipmentconnected to communications lines(telephone, Ethernet, R,
etc.).
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.
What skills should lightning protectors have in the selection?
1.Confirm power supply system
First of all, you must determine what your power distribution
system is like, whether it is TT, TN or IT system. After
determining the power distribution system, you can choose the
protection mode and wiring method of the lightning arrester to
select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses
4P, TT uses 3P+N, etc.
2.Know the main parameters of the lightning arrester.
