In 20KA Type 1+2 Surge Protector , Nylon Active Lightning Protction 34V AC

Product Specification

 Active Lightning Voltage Type 1+2 Surge Protection For Power Supply
According to the GB50057-2010 building lightning protection design code, the national standard requirements: a surge protector with Class I test should be installed at the main distribution box where the power supply is introduced. The voltage protection level value of the surge protector should be less than or equal to 2.5 kV. When the impulse current value Iimp of each protection mode cannot be determined, the impulse current should be equal to or greater than 12.5 kA.
Therefore, the first-level surge protector needs to choose products with T1 test (10/350μs test waveform) parameters, and the impulse current Iimp≥12.5kA.
At present, the lightning protection of buildings must be tested in accordance with the T1 surge protector in the main incoming cabinet!
 
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.
