Product Description

Type 2 Surge Protector Capable Of Realizing Fast Response Time And Low Protection Level
OBV5-C40


The surge arrestors OBV5-C40-LT meet the type 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 disary. In addition, the QR code printed on the arrestor allows direct access to the online installation instructions.

Necessity of lightning protection detection: lightning protection detection surge protector can resist lightning disasters and ensure life safety

The damage of lightning to buildings can only be avoided through lightning protection devices. Lightning directly hits buildings or equipment exposed to the air, and various overhead metal cables will cause equipment damage, and even more serious fires will cause people to bring damage to the equipment. Unnecessary property damage. Professional lightning protection testing companies can do professional lightning protection. The lightning protection testing is to check whether the installed lightning protection devices or structural equipment are reasonable, whether the protection conditions meet the requirements, and whether the electrical safety meets the standards. If it fails to meet the requirements, the lightning protection inspection company will promptly put forward corresponding rectification opinions;

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/or communications 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.
