EN61000-4-5 Lighting Surge Immunit System with 1.2 / 50us Output Voltage Waveform
1.Standard of Lighting Surge System:
IEC/EN61000-4-5, IEC/EN61850-3, ITU-T K.12, ITU-T K.20, ITU-T K.45, UL1449
2. Introduction of Lighting Surge System:
LSG-6K10 Lighting Surge System includes: 1.2/50ms Surge Generator, single phase CDN, Voltage waveform attenuator, current waveform attenuator, voltage wave peak ( or the residual voltage wave peak) testing equipment, current wave peak testing equipment, EUT working current and voltage testing equipment.
LSG-6K10 Lighting Surge System is confirmed to IEC61000-4-5 and GB/T17626.5. It is the equipment used for Anti-Surge performance test for electronic and electrical products in the industry process measurement and control device. It includes Coupling/ Decoupling Network (CDN), which can be used for the Surge immunity test in the power line.
3. Features of Lighting Surge System:
1). 7 inches LCD touch screen, with plentiful functions, easy to operation and update the software.
User can design the test program, and has 1000 groups memories.
2). Monitoring the surge voltage and current waveform by work with an external oscilloscope.
3). Built in single phrase 10A (16A) network, makes the equipment smaller and convenient.
4). With high-strength plug in the panel, EUT can connect with the equipment convenient and reliable.
5). Monitoring the work voltage and current of the EUT. Overvoltage protection and overcurrent protection.
6). Intelligent test the surge output, warning at voltage error and no output.
7). Intelligent judge the abnormal of high voltage and surge output.

5. Initial Interface of the Lighting Surge System
There are two main reasons causing lightning shock:
- Switching Transients:
Switching transients is related with the following factors:
- The Lightning Transient
The generating mechanism of lightning transient:
