Product Description

 Power Surge Protection Device / Class I+II Surge Arrester For Security Systems
The DC surge protector is an electronic device that provides safety protection for various electrical lightning protection sub-equipment, instrumentation, and communication lines. When the peak current or voltage in the protected circuit or electrical circuit is caused by external force majeure factors, the DC surge protector can conduct and shunt in a very short time, thereby avoiding the surge phenomenon from causing the protected equipment or circuit damage.
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.
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.

Comprehensive protection
An effective overvoltage protection must combine thefollowing protection systems:
External protection (ESE lightning rods and faradization).System for protection against direct lightningstrike.These capture the lightning within the protectedarea and lead it, in a controlled manner, safely to ground. Internal protection (power frequency overvoltage andsurge protection devices). Equipment designed to protectagainst the effects of overvoltages in equipment connected to the power supply systems and/orcommunications networks.Grounding systems (grounding and insulation monitoring).Systems that allow atmospheric dischargecurrents to be dispersed into the ground. The need formonitoring the grounding system.CUAJE offers a widerange of products for each of these systems. It alsodevelops custom products, provides advice and consultingservices and the best possible aftersales service.
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.
